.TH Shell 3 "2002-06-01" "perl v5.8.0" "Perl Programmers Reference Guide"
Shell \- run shell commands transparently within perl
\& Date: Thu, 22 Sep 94 16:18:16 -0700
\& Message-Id: <9409222318.AA17072@scalpel.netlabs.com>
\& To: perl5-porters@isu.edu
\& From: Larry Wall <lwall@scalpel.netlabs.com>
\& Subject: a new module I just wrote
Here's one that'll whack your mind a little out.
\& $foo = echo("howdy", "<funny>", "world");
\& $passwd = cat("</etc/passwd");
\& cp("/etc/passwd", "/tmp/passwd");
That's maybe too gonzo. It actually exports an \s-1AUTOLOAD\s0 to the current
package (and uncovered a bug in Beta 3, by the way). Maybe the usual
\& use Shell qw(echo cat ps cp);
If you set \f(CW$Shell::capture_stderr\fR to 1, the module will attempt to
capture the \s-1STDERR\s0 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:
and of course, this is wrong.
I have fixed this bug, it was brought up by Wolfgang Laun [\s-1ID\s0 20000326.008]
.Sh "\s-1OBJECT\s0 \s-1ORIENTED\s0 \s-1SYNTAX\s0"
.IX Subsection "OBJECT ORIENTED SYNTAX"
Shell now has an \s-1OO\s0 interface. Good for namespace conservation
and shell representation.
