ffpath — – Search $PATH for file(s)

November 2, 2009

This is a utility script that operates similarly to the find file (ff.sh) script previously presented. But instead of searching a directory tree, it searches the components of a $PATH environment variable.

Example usage:
    $ ffpath javac jdb; # Find the Java compiler and debugger
    $ ffpath -m myscript1 myscript2; # Display the myscript1 and myscript2 scripts using more
    $ ffpath -v PERL5LIB -s’;’ -e ‘pod2text’ sybdbi.pm; # Find and convert the Sybase DBi Perl doc to text

#! /bin/sh

#  Description: Search $PATH for file(s)

#                        -s fs      Use 'fs' for the directory field separator
#                        -l         list file info using 'ls -l' long format (default)
#                        -1         list one file per line ie: 'ls -1'
#                        -c         Use 'cat' to display the file
#                        -m         Use 'more' to display the file
#                        -e prog    Run 'prog' on file
