| Functions for processes and process groupsExecute a system command and collect standard outputDaftar Isi - 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 (potentiallymulti-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 $_.
