{p 4 22 2}
{cmd:_getfilename} {hline 2} Utility commands for handling path-filename
specifications


{title:Syntax}

{p 8 8 2}{cmd:_getfilename} {cmd:`"}{it:path-filename}{cmd:"'}

{p 8 8 2}{cmd:_shortenpath} {cmd:`"}{it:path-filename}{cmd:"'}{cmd:,}
{cmd:len(}{it:#}{cmd:)} [ {cmd:head(}{it:str}{cmd:)} ]


{title:Description}

{pstd}{cmd:_getfilename} returns in {cmd:r(filename)} the name of
the file (with extension), stripping off drive and directory
information.  Also see {helpb findfile} for a related command.

{pstd}{cmd:_shortenpath} returns in {cmd:r(pfilename)} a shortened
path-filename string of length at most {cmd:len}.  Shortening is
accomplished by replacing leading directories by a single {cmd:*},
denoting `some string'.  {cmd:_shortenpath} never shortens the
filename itself, and leading directories are represented by a string
at least as long as  {cmd:*\}, so {cmd:_shortenpath} may actually
return a string longer than {cmd:len}.


{title:Options}

{phang}{cmd:len(}{it:#}{cmd:)} ({cmd:_shortenpath} only)
is not optional. It specifies the length to which the {it:path-filename}
should be shortened.

{phang}{cmd:head(}{it:#}{cmd:)} ({cmd:_shortenpath} only)
specifies the string used to represent the leading directories removed
from the head of {it:path-filename}.  It defaults to {cmd:*}.


{title:Examples}

{phang}{cmd:. _getfilename c:\archive\stata\data\hin95.dta}{break}
{txt:r(filename):} {res:hin95.dta}

{phang}{cmd:. _shortenpath c:\archive\stata\data\hin95.dta, len(20)}{break}
{txt:r(pfilename):} {res:*\data\hin95.dta}

{phang}{cmd:. _shortenpath c:\archive\stata\data\hin95.dta, len(5)}{break}
{txt:r(pfilename):} {res:*\hin95.dta}
