basename pathname [suffix ]

Given a pathname , strip the path prefix and leave just the filename, which is printed on standard output. If specified, a filename suffix (e.g., .c ) is removed also. basename is typically invoked via command substitution (` ...` ) to generate a filename. See also dirname .

The Solaris version of basename allows the suffix to be a pattern of the form accepted by expr . See the entry for expr for more details.


Given the following fragment from a Bourne shell script:

myname="`basename $0`"
echo "$myname: QUITTING: can't open $ofile" 1>&2
exit 1

If the script is called do_it , the following message would be printed on standard error:

do_it: QUITTING: can't open output_file
