if (my $temp2=$b2e_r->cmd(cmd=>"dos2unix $b2e_file_name"))



Even if it fails as,

Jul 25 17:17:02 [INFO ] [server1] [cmd] dos2unix /volume/systest/hello_manoj.results
dos2unix /volume/systest/hello_manoj.results
dos2unix: converting file /volume/systest/hello_manoj.results to UNIX format ...
Failed to open output temp file: No space left on device
dos2unix: problems converting file /volume/systest/hello_manoj.results
JT_364_server1:
TEMP2: 1



The return value is 1. How shall i detect whether it fails or not?

Thanks,

Zero means success for command utilities and non-zero - failure. It's just opposite perl conventions for true/false values. So you need:

Code:

if (! ...) {
  print "success\n";
}
else {
 ...
}

Thanks yazu,

But for success also am getting 1.

Thats the issue.

it's problem of your $br2e_r object:

Code:

% perl -E 'say system "qwe"'
-1
jazu@uf3 ~ 
% perl -E 'say system "date >/dev/null"'
0
