.SH Name
cd \- change current directory
.SH Syntax
.B cd
\fIdirectory\fR
.SH Description
.NXR "cd command (csh)"
.NXR "cd command (sh)"
.NXR "cd command (System V)"
.NXR "working directory" "changing"
The
.I directory
becomes the new working directory.
The process must have execute (search)
permission in
.I directory.
.PP
Because a new process is created to execute each command,
.PN cd
would be ineffective if it were written as a
normal command.  It is therefore recognized and executed
by the shells.
In 
.PN csh
you may specify a list of directories in which
.I directory
is to be sought as a subdirectory if it is not
a subdirectory of the current directory;
see the description of the
.I cdpath
variable in
.MS csh 1 .
