awk

Best Awk Commands

I find AWK really useful. Here is a one liner I put together to manipulate data.

ls | awk '{ print "awk " "'"'"'"  " {print $1,$2,$3} " "'"'"'"  " " $1 ".old_ext > " $1    ".new_ext"  }' > file.csh

I used this AWK to make a script file that would rename some files and only print out selective columns. Anyone know a better way to do this? What are you best AWK one liners or clever manipulations?

Solution

  • The AWK book is full of great examples. They used to be collected for download from Kernighan's webpage (404s now).
