     alias [word] [text ...]
          Causes word to be aliased to text.  History substitu-
          tions may be used, as in C-shell aliases.

     unalias [word ...]
          Removes any aliases present for the words.

     history [number]
          Print out the history, or the last number commands
          typed at the keyboard.  _N_o_t_e: in  version 3a7 and ear-
          lier, all commands (including ones read from files)
          were saved.

     set [word] [word = value] ...
          Set the value of word to be value, if it is present.
          You can set any word to be any value, numeric or
          string.  If no value is given then the value is the
          boolean 'true'.   The value of _w_o_r_d may be inserted
          into a command by writing $_w_o_r_d.  If a variable is set
          to a list of values that are enclosed in parentheses
          (which must be seperated from their values by white
          space), the value of the variable is the list.  The
          variables meaningful to nutmeg (of which there are too
          many) are:

                     abstol
                     The absolute tolerance used by the diff com-
                     mand.

                     appendwrite
                     Append to the file when a write command is
                     issued, if one already exists.

                     color_N
                     These variables determine the colors used,
                     if X is being run on a color display.  _N may



                                                                7

                     be between 0 and 15.  Color 0 is the back-
                     ground, color 1 is the grid and text color,
                     and colors 2 through 15 are used in order
                     for vectors plotted.  The value of the color
                     variables should be names of colors, which
                     may be found in the file /usr/lib/rgb.txt.

                     combplot
                     Plot vectors by drawing a vertical line from
                     each point to the X-axis, as opposed to
                     joining the points.  Note that this option
                     is subsumed in the _p_l_o_t_t_y_p_e option, below.

                     cpdebug
                     Print _c_s_h_p_a_r debugging information. (Must be
                     complied with the -DCPDEBUG flag.)

                     debug
                     If set then a lot of debugging information
                     is printed. (Must be compiled with the
                     -DFTEDEBUG flag.)

                     device
                     The name (/dev/tty??) of the graphics dev-
                     ice. If this variable isn't set then the
                     user's terminal is used. To do plotting on
                     another monitor you will probably have to
                     set both the device and term variables.  (If
                     device is set to the name of a file, nutmeg
                     will dump the graphics control codes into
                     this file -- this is useful for saving
                     plots.)

                     echo
                     Print out each command before it is exe-
                     cuted.

                     filetype
                     This can be either ascii or binary, and
                     determines what the format of _r_a_w_f_i_l_e_s will
                     be. The default is ascii.

                     fourgridsize
                     How many points to use for interpolating
                     into when doing fourier analysis.

                     gridsize
                     If this variable is set to an integer, this
                     number will be used as the number of equally
                     spaced points to use for the Y-axis when
                     plotting.  Otherwise the current scale will
                     be used (which may not have equally spaced

                     points).  If the current scale isn't
                     strictly monotonic, then this option will
                     have no effect.

                     hcopydev
                     If this is set, when the hardcopy command is
                     run the resulting file is automatically
                     printed on the printer named hcopydev with
                     the command _l_p_r -_Phcopydev -_g file.

                     hcopydevtype
                     This variable specifies the type of the
                     printer output to use in the hardcopy com-
                     mand.  If hcopydevtype is not set, plot (5)
                     format is assumed.  The standard distribu-
                     tion currently recognizes postscript as an
                     alternative output format.  When used in
                     conjunction with hcopydev, hcopydevtype
                     should specify a format supported by the
                     printer.

                     height
                     The length of the page for asciiplot and
                     print col.

                     history
                     The number of events to save in the history
                     list.

                     nfreqs
                     The number of frequencies to compute in the
                     fourier command. (Defaults to 10.)

                     nobreak
                     Don't have asciiplot and print col break
                     between pages.

                     noasciiplotvalue
                     Don't print the first vector plotted to the
                     left when doing an asciiplot.

                     noclobber
                     Don't overwrite existing files when doing IO
                     redirection.

                     noglob
                     Don't expand the global characters `*', `?',
                     `[', and `]'. This is the default.

                     nogrid
                     Don't plot a grid when graphing curves (but
                     do label the axes).



                                                                9






NUTMEG(1)                                           27 April 1987



                     nomoremode
                     If nomoremode is not set, whenever a large
                     amount of data is being printed to the
                     screen (e.g, the print or asciiplot com-
                     mands), the output will be stopped every
                     screenful and will continue when a carriage
                     return is typed. If nomoremode is set then
                     data will scroll off the screen without
                     hesitation.

                     nonomatch
                     If noglob is unset and a global expression
                     cannot be matched, use the global characters
                     literally instead of complaining.

                     nosort
                     Don't have display sort the variable names.

                     noprintscale
                     Don't print the scale in the leftmost column
                     when a print col command is given.

                     numdgt
                     The number of digits to print when printing
                     tables of data (fourier, print col).  The
                     default precision is 6 digits.  On the VAX,
                     approximately 16 decimal digits are avail-
                     able using double precision, so numdgt
                     should not be more than 16.  If the number
                     is negative, one fewer digit is printed to
                     ensure constant widths in tables.

                     plottype
                     This should be one of _n_o_r_m_a_l, _c_o_m_b, or
                     _p_o_i_n_t:chars.  _n_o_r_m_a_l, the  default, causes
                     points to be plotted as parts of connected
                     lines.  _c_o_m_b causes a comb plot to be done
                     (see the description of the _c_o_m_b_p_l_o_t vari-
                     able above).  _p_o_i_n_t causes each point to be
                     plotted seperately - the chars are a list of
                     characters that will be used for each vector
                     plotted.  If they are omitted then a default
                     set is used.

                     polydegree
                     The degree of the polynomial that the plot
                     command should fit to the data. If _p_o_l_y_d_e_-
                     _g_r_e_e is N, then nutmeg will fit a degree N
                     polynomial to every set of N points and draw
                     10 intermediate points in between each end-
                     point. If the points aren't monotonic, then
                     it will try rotating the curve and reducing

                     the degree until a fit is achieved.

                     polysteps
                     The number of points to interpolate between
                     every pair of points available when doing
                     curve fitting. The default is 10. (This
                     should really be done automatically.)

                     program
                     The name of the current program (_a_r_g_v[_0]).

                     The prompt, with the character `!' replaced
                     by the current event number.

                     rawfile
                     The default name for rawfiles created.

                     reltol
                     The relative tolerance used by the diff com-
                     mand.

                     rhost
                     The machine to use for remote SPICE-3 runs,
                     instead of the default one. (See the
                     description of the rspice command, below.)

                     rprogram
                     The name of the remote program to use in the
                     rspice command.

                     slowplot
                     Stop between each graph plotted and wait for
                     the user to type return before continuing.

                     sourcepath
                     A list of the directories to search when a
                     source command is given.  The default is the
                     current directory and the standard spice
                     library (/_u_s_r/_l_o_c_a_l/_l_i_b/_s_p_i_c_e, or whatever
                     LIBPATH is #defined to in the  source.

                     spicepath
                     The program to use for the aspice command.
                     The default is /cad/bin/spice.

                     term
                     The _m_f_b name of the current terminal.

                     units
                     If this is degrees, then all the trig func-
                     tions will use degrees instead of radians.



                                                               11

                     unixcom
                     If a command isn't defined, try to execute
                     it as a UNIX command.  Setting this option
                     has the effect of giving a rehash command,
                     below.  This is useful for people who want
                     to use nutmeg as a login shell.

                     verbose
                     Be verbose. This is midway between echo and
                     debug / cpdebug.

                     vntol
                     The absolute voltage tolerance used by the
                     diff command.

                     width
                     The width of the page for asciiplot and
                     print col.

                     xbrushheight
                     The height of the brush to use if X is being
                     run.

                     xbrushwidth
                     The width of the brush to use if X is being
                     run.

                     xfont
                     The name of the X font to use when plotting
                     data and entering labels.  The plot may not
                     look entirely great if this is a variable-
                     width font.

     unset [word] ...
          Unset the variables word.

     shift [varname] [number]
          If _v_a_r_n_a_m_e is the name of a list variable, it is
          shifted to the left by _n_u_m_b_e_r elements. (I.e, the
          _n_u_m_b_e_r leftmost elements are removed.)  The default
          _v_a_r_n_a_m_e is argv, and the default _n_u_m_b_e_r is 1.

     rusage [resource ...]
          Print resource usage statistics.  If any resources are
          given, just print the usage of that resource.
          Currently valid resources are:

                     elapsed
                     The amount of time elapsed since the last
                     rusage elaped call.

                     Number of page faults and context switches
                     (BSD only).

                     space
                     Data space used.

                     time
                     CPU time used so far.

                     everything
                     All of the above.

                     directory, or to the user's home directory
                     if none is given.

     aspice [output-file]
                     Start a SPICE-3 run, and when it is finished
                     load the data. The raw data is kept in a
                     temporary file. If _o_u_t_p_u_t-_f_i_l_e is specified
                     then the diagnostic output is directed into
                     that file, otherwise it is thrown away.

     jobs            Report on the asynchronous SPICE-3 jobs
                     currently running.  Nutmeg checks to see if
                     the jobs are finished every time you execute
                     a command.  If it is done then the data is
                     loaded and becomes available.

     rspice [input file]
                     Runs a SPICE-3 remotely taking the input
                     file as a SPICE-3 input deck, or the current
                     circuit if no argument is given. Nutmeg
                     waits for the job to complete, and passes
                     output from the remote job to the user's
                     standard output. When the job is finished
                     the data is loaded in as with aspice. If the
                     variable _r_h_o_s_t is set, nutmeg will connect
                     to this host instead of the default remote
