- readpipe EXPR
-
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 perlop/"I/O Operators".
