paste, cut one liner conversation from bash to csh

bioinformatics_guy · 09-02-2009, 09:32 AM

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:

Code:

nawk '{ printf "%s %s ", $3, $4; getline < "file2"; print $3, $4 }' file1 > foo.txt

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
