no error message from PERL when i use bash command
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
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.
