Hi All, I have a shell script which I use to call a ruby program. I pass parameters from the shell script to the ruby program Example: #!/bin/csh -f set DEST_DIR=/home/vandana/ ruby test.rb -p $DEST_DIR ---------------------------------- When I execute the above, I get the error "Cannot convert nil to String. I know that $DEST_DIR is not empty because when I do an echo $DEST_DIR I see the /home/vandana/ What am I missing here? ---------------------------------------- If I put the command "ruby test.rb -p $DEST_DIR" in quotes I get the message command not found. Please help! Thanks,
