I'm trying to pass the output from bash command to perl variable in a perl script, and I used the "system" command to execute the bash statment and pass the result to perl string variable, in this perl script I used a variable $file that store data for using it as a regular expression.
Here I show you some part of the script:
Output: in the screen the script prints 0
The result I want obtain is the path found by grep allocated in the perl variable $output.
the only I have obtained is a zero allocated in $output perl variable. I have tried the bash one-line script in linux terminal and it works very fine because it shows me the correct result I want.
I would appreciate if you can help me to solve this

You have assigned the exit status of the Unix command to the Perl variable $output. Since the command was successful, its exit status was 0 and so it gets assigned to $output.
If you want to assign the output of the Unix command to a Perl variable, then use backticks (``) or qx// function.
