perl function readpipe
The readpipe function in Perl is a synonym for the backtick operator (), which is used to capture the output of a command as a string. Thereadpipe` function returns the standard output of the command as a scalar value.
Here's an example:
r:ot refetheitroad.commy $result = readpipe("ls -l");
print "The output of ls -l is: $result\n";
In this example, the ls -l command is executed, and its output is captured as a string in the $result variable. The print statement then displays the captured output.
