Hey Baho, Well, your login rc files (such as .cshrc or whatever other rc or profies files are executed, they set your default shell to (as you indicated) /bin/csh. Since you do not want to change that, then I suggest that your shell script you are working with have this code just after the shebang line: export SHELL=/bin/sh then code you functions and script after that. The shell variable value will only affect the shell you are executing and any other shell scripts you run from there (as long as those shell scripts are shebanged with #!/bin/sh and do not reset the SHELL variable value. HTH
