Perl Programming/Keywords/readpipe
The readpipe keyword
editreadpipe executes EXPRESSION as a system command and returns the collected standard output. If called from scalar context, a string is returned. If called from list context, a list of lines as defined by $/ or $INPUT_RECORD_SEPARATOR is returned. This is the internal implementation of the qx/EXPRESSION/ operator.
