Re^2: How to Execute unix commands like "WC, tail, Gunzip, ZIP" against a file which is read from directory

Hi Monks,

Thanks for your valuable suggestion.

i have used the below code and it works for me

can we store the value of unix command in some variable because when we execute the unix command it will either return 0 or 1, i want to store the value


chdir($dir);
    foreach my $file (@files) {
        if ($file=~ m/orig/) {
        my $lcmd = system("gunzip -c $file|tail -1");
}
[download]

Output:

123456|345627899292|000108418|
[download]

i want to store the value 123456|345627899292|000108418| in variable so that i can use substr to fetch '000108418'

Thanks a lot for the valuable inputs

thanks & regards,

Maybe you want to read about what the "backticks" operator does. Consult perlop about `qx` or "backticks". Also, in your code snippet, the variable `$result` was given a name that might indicate its use.	[reply] [d/l] [select]
