TIL how to use in-place sed on Mac.
I always thought I have to use the GNU tools version of sed for in-place sed, but I was wrong. Mac sed supports in-place editing as well.
sed -i '' '/pattern/d' ./infile
There is a caveat though:
Edit files in-place, saving backups with the specified extension. If a zero-length extension is given, no backup will be saved. It is not recommended to give a zero-length extension when in-place editing files, as you risk corruption or partial content in situations where disk space is exhausted, etc.
Replace all occurances of
barin the file test.txt, without creating a backup of the file:
sed -i '' -e 's/foo/bar/g' test.txt
