You're running the script with sh, not with bash. If you are typing "sh myscript", that immediately identifies the source of the problem. You're literally telling it to run with "sh" as its interpreter. Replace the "sh" with "bash". Ideally, a script will be installed into a directory in $PATH, and then invoked with its filename. When that happens, the operating system should read the first few bytes of the script (program) to see how to run it. If the first two bytes are #! then the characters after that identify the interpreter that should be used. That's why a bash script should begin with #!/bin/bash instead of #!/bin/sh . > you sure its bash u run ? echo $SHELL and see The $SHELL variable will not help here. That doesn't tell you what shell is in use. In only tells you what shell is defined for your user account in /etc/passwd. unicorn:~$ cat foo echo "$SHELL" unicorn:~$ bash foo /bin/bash unicorn:~$ dash foo /bin/bash unicorn:~$ zsh foo /bin/bash
