shell script

Vandana

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,

Thanks samba.

the echo...strange

It's strange.
Don't you have another "ruby" command written in shell script?
