paste, cut one liner conversation from bash to csh
 

I have the line:

paste <(cut -f3,4 file1) <(cut -f3,4 file2) > foo.txt

Can I do this in csh? It only works in bash.

Nope. Process substitution is a bash feature (and zsh if I remember well). In csh you have to find a workaround to achieve the same task. For example using gawk or nawk:

Brilliant! Thanks for the reply. I wanted to do it with awk but I couldn't figure out how to pass it multiple files. The problem was, I was making a system command call from perl and thought it was interpreting using csh instead of bash... come to find out, it was interpreting with the "sh" shell :)
