hi,

I am using ubuntu 9.10 and perl5.10.1. I have a strange problem. I am trying to call a program (using bash command) from perl. for eg

`/home/nitin/software/clustalw filename`;

I knew that there is no file "clustalw" in this path. I expect perl to warn "No such file or directory" But in my case, there is no error message or warning message.

Kindly help me to solve this.

It's up to you to grab the return code from the call and do something with it

cheers

See the qx section here http://perldoc.perl.org/perlop.html#...Like-Operators for a full explanation plus example howtos.
