Shell - run shell commands transparently within perl
Date: Thu, 22 Sep 94 16:18:16 -0700 Message-Id: <9409222318.AA17072@scalpel.netlabs.com> To: email@example.com From: Larry Wall <firstname.lastname@example.org> Subject: a new module I just wrote
Here's one that'll whack your mind a little out.
#!/usr/bin/perl use Shell; $foo = echo("howdy", "<funny>", "world"); print $foo; $passwd = cat("</etc/passwd"); print $passwd; sub ps; print ps -ww; cp("/etc/passwd", "/tmp/passwd");
That's maybe too gonzo. It actually exports an AUTOLOAD to the current package (and uncovered a bug in Beta 3, by the way). Maybe the usual usage should be
use Shell qw(echo cat ps cp);
If you set $Shell::capture_stderr to 1, the module will attempt to capture the STDERR of the process as well.
The module now should work on Win32.
There seemed to be a problem where all arguments to a shell command were quoted before being executed. As in the following example:
really turned into:
cat '</etc/passwd' ls '*.pl'
cat </etc/passwd ls *.pl
and of course, this is wrong.
I have fixed this bug, it was brought up by Wolfgang Laun [ID 20000326.008]
OBJECT ORIENTED SYNTAX
Shell now has an OO interface. Good for namespace conservation and shell representation.
use Shell; my $sh = Shell->new; print $sh->ls;
