You can't nest the backticks. How would the shell know which one was meant to be the start of a command and which was the end? Bash has the $() syntax which allows for nesting of multiple commands. Be aware that if you use that syntax, you should change the #! in your script from /bin/sh to /bin/bash if you're concerned about the script being portable to systems where /bin/sh and /bin/bash are not always the same. Adrian, what you want can be written like this: $(tail -n 1 $(date "+%Y-%m-%d-%H").txt) -- Todd OpenPGP -> KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Money frees you from doing things you dislike.
