readpipe EXPR

readpipe

EXPR is executed as a system command. The collected standard output of the command is returned. In scalar context, it comes back as a single (potentially multi-line) string. In list context, returns a list of lines (however you've defined lines with $/ or $INPUT_RECORD_SEPARATOR ). This is the internal function implementing the qx-EXPR- operator, but you can use it directly- The qx-EXPR- operator is discussed in more detail in I/O Operators in perlop. If EXPR is omitted, uses $_ .
