The PPT which Command
This is the home page for the Perl Power Tools
implementation of the standard which command.
Current Perl implementations are:
- A version and its manpage by abigail, as
enhanced by Peter Prymmer.
- A slightly different thing, pgrep by tchrist.
This accept regexes as arguments. It might be nice to merge these
somehow.
This too assumes a ":" to separate
elements of $ENV{PATH}, which needs fixing.
- Here's a simple version by
Nick Ing-Simmons.
This one assumes a ";" to separate
elements of $ENV{PATH}, which needs fixing.
(This one has a batch file for CP/M
derisibles.)
Baseline documentation:
- BSD (with POSIX.2 info, if relevant)
