run a program and capture stdout and completion status?

hansel on 2006-02-12T22:20:22

I'm looking for a snippet or simple module that run an external command and capture the completion status and stdout. I found some partial snippets in the camel book, but I'd really prefer something a bit more tested/complete. This is my note to dive into CPAN. Any suggestions are appreciated.

Backticks

According to perlop, you can simply use backticks AKA qx to run the external command and capture STDOUT; the status will be returned in $?.

A string enclosed by backticks (grave accents) first undergoes double-quote interpolation. It is then interpreted as an external command, and the output of that command is the value of the backtick string, like in a shell. In scalar context, a single string consisting of all output is returned. In list context, a list of values is returned, one per line of output. (You can set $/ to use a different line terminator.) The command is executed each time the pseudo-literal is evaluated. The status value of the command is returned in $? (see perlvar for the interpretation of $? ).
