out put from system()

[ecnalbya]

Are there any ways to get system output from Perl? I want to get out
put from system() and print it out in Perl. For example,


#! /use/bin/perl
$output = system ("echo hello world");
print $output;

put from system() and print it out in Perl. For example,


#! /use/bin/perl
$output = system ("echo hello world");
print $output;

either use back ticks `echo "hello world!"`
or the qx operator ...

# without any interpolation of variables or expressions
...
$output = qx'echo "hello world!"';
print $output;
...

# interpolation of variables or expressions
...
$text = "hello world!";
$output = qx{echo $text};
print $output;
...

You asked a FAQ.

perldoc -q output.+system

Btw, did you consider to read the docs for the function you thought you
want to use?

perldoc -f system
