Find and Replace a Bunch
Reposted from original article
Say I'm writing a journal and want to make sure I'm not leaking names. I'd like to change it consistently so it's anonymous, but still makes sense.
Instead of this
John force-pushed to `master` for some reason. Harold didn't pull before he
added his fix and Betty ended up cherry-picking into yet another branch. To

Farmboy force-pushed to `master` for some reason. Jimmybob didn't pull before
he added his fix and Horsenator ended up cherry-picking into yet another
branch. To avoid this, next time we could...Find-and-replace is what I want to do, but consistently and repeatedly (and quickly!).
sed is the tool for the job.First, define the replacements in files named
encode and decode.s/Betty/Horsenator/g
s/Harold/Jimmybob/g
s/John/Farmboy/gs/Horsenator/Betty/g
s/Jimmybob/Harold/g
s/Farmboy/John/gThen to replace, we use one of
sed -i "" -f encode journal.md
sed -i "" -f decode journal.mdObviously, we don't want to keep the encode/decode files with the output, but you get the idea. You can also send a whole bunch of files through
sed with this set up. Maybe you could add a build step that cleans up content or something.You can find an example here to play with.
