In the code I am printing the list of files. In that it showing files. But while trying to read it's showing error like this.

 
[root@ems NSN_SGSN]# perl gun.pl
$VAR1 = [
          'generate_ASR_PSR_report.pl.gz',
          'generate_nsn_sgsn_report.pl.gz'
        ];
Couldn't read [gzip -cd "generate_ASR_PSR_report.pl.gz"]: No such file
+ or directory at gun.pl line 20.
