how to include single quotes from user input in perl -


the user going enter input string such tom's toy. perl script complains saying "unmatched '."

this code.

my $commandline=""; while (@argv) {   $_ = shift @argv;   {$commandline .= $_ . ' ';} } print " running $commandline\n"; system ($commandline);

now if user input tom's toy. want print tom's toy. perl complains "unmatched '.". if dont user quote works fine. (for eg: tom toy good) how fix issue.

any appreciated. in advance

if switch things around little use system $cmd, @args version of function, no shell invoked, no escaping necessary.

my $cmd = shift @argv; @args = @argv; print " running $cmd\n";  system $cmd, @args;

i tested ./test.pl echo tom\'s toy , gives expected output:

 running echo tom's toy
