in reply to sed isn't working within a perl script

system("sed -ie 's/\(.*\)/Number => \1/' test.txt");
See the difference:
say "sed -ie 's/\(.*\)/Number => \1/' test.txt"; say qq{sed -ie 's/\(.*\)/Number => \1/' test.txt}; say q{sed -ie 's/\(.*\)/Number => \1/' test.txt}; __END__ sed -ie 's/(.*)/Number => /' test.txt sed -ie 's/(.*)/Number => /' test.txt sed -ie 's/\(.*\)/Number => \1/' test.txt
Double quotes do interpolate your backslashes, and they are lost when you run the command. You need a non-interpolating quote operator instead to pass your string unchanded to the shell.

And I strongly advice you to use native Perl code instead, too.

Sorry if my advice was wrong.
