Self? Remember this:
tr 't' ' ' | sed -e 's/ */ /gp'
You’ll need it later.
At work I use bash, sed, [e]grep, cut, tr, and occasionally awk if I can’t get out what I need from the others. These aren’t used as scripts per se, just some tools I use to massage data.
Need that formatted, irregular, multi-line text file broken up and ripped into another format for processing? Sure, not a problem. Most people would (correctly) use PERL but I never got into it that much. I hardly ever get the same situation twice and deal with new data all the time.
But I do need to remove tabs and multiple spaces almost every time. While I always remember the tr part, I always need to rethink the sed regular expression. So here I am, writing a post to myself to keep it in my mind.
