I am trying to match a pattern exactly in a shell script. I have tried two methods
awk '/\<mpath${CURR_MP}\>/{print $1 $2}' multipath
perl -ne '/\bmpath${CURR_MP}\b/ and print' /var/tmp/multipath
Both these methods require that I use the escape character. I am guessing that is why... (8 Replies)

pwhich
PWHICH(1) User Contributed Perl Documentation PWHICH(1) NAME
pwhich - Perl-only `which' SYNOPSIS
$ pwhich perl $ pwhich -a perl # print all matches $ pwhich perl perldoc ... # look for multiple programs $ pwhich -a perl perldoc ... DESCRIPTION
`pwhich' is a command-line utility program for finding paths to other programs based on the user's "PATH". It is similar to the usualy Unix tool `which', and tries to emulate its functionality, but is written purely in Perl (uses the module "File::Which"), so is portable. Calling syntax $ pwhich [-a] [-v] programname [programname ...] Options -a The option -a will make "pwhich" print all matches found in the "PATH" variable instead of just the first one. Each match is printed on a separate line. -v Prints version (of "File::Which") and copyright notice and exits. SUPPORT
Bugs should be reported via the CPAN bug tracker at http://rt.cpan.org/NoAuth/ReportBug.html?Queue=File-Which <http://rt.cpan.org/NoAuth/ReportBug.html?Queue=File-Which> For other issues, contact the maintainer. AUTHOR
Adam Kennedy <adamk@cpan.org> Per Einar Ellefsen <pereinar@cpan.org> Originated in modperl-2.0/lib/Apache/Build.pm. Changed for use in DocSet (for the mod_perl site) and Win32-awareness by me, with slight modifications by Stas Bekman, then extracted to create "File::Which". Version 0.04 had some significant platform-related changes, taken from the Perl Power Tools `which' implementation by Abigail with enhancements from Peter Prymmer.
