readpipe


SYNOPSIS

readpipe EXPR


DESCRIPTION

EXPR is interpolated and then executed as a system command. The collected standard output of the command is ret urned. In scalar context, it comes back as a single (potentially multi-line) string. In list context, returns a list of lines (howev er 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.
