I've been a Linux user for a while, and I've a pretty decent understanding of most the common command line utilities. However, ones that come up and up again in relation to programming are grep, awk, and sed.About the only thing I've used grep for is piping stuff into it to find files in log files, the output of ps etc. I haven't used awk or sed at all. Are there any good tutorials for these utilities?
Is there a basic tutorial for grep, awk and sed?
