There are plenty of ways to do this. The easiest if errors and warnings can be ruled out and the output is small is the backtick operator which is also a similar operator in bash: my $output = `thing.sh args`;
If output is extensive, but nevertheless nothing is expected to be printed to *nix channel 2, a pipe can be opened:
my $pid = open my $ph, "thing.sh args |"
or die $!;
while ( <$ph> ) {
# process output from thing.sh
}
close $ph;
waitpid $pid, 0;
If errors and output need separate processing (otherwise can append 2>&1 to the command in option 2), see IPC::Run3 or IPC::Open3, the latter of which takes three filehandles for channels 0 thru 2, the 0 channel needing therefore undef() instead of a filehandle, but otherwise is similar to option 2 above. Finally, if no I/O system communication is required with the process, just pass the commandline to be executed in bash (in this case the autoinvocation with arguments" to the "system" function as a single argument.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
