grep.txt

grep -R (recurse through subdirectories)
grep -i (Case insensitive)
grep -e (extended regex, allows for regex modifiers)
grep -l (only returns file name)

grep -Rle 'aligne\b' | xargs sed -i 's/aligne\b/align/'g
# search for the string 'aligne' (don't returns strings like 'aligned')
# pass all files that have said string to xargs which quickly processes
# sed (with the -i flag to process in place)

# Copying commits from other repos
## This will print the diff, 
## then grep all lines that start with '+' and a letter or number (needs other conditions as well
## the truncates the '+' of the beginning of the result
## copies everything to the buffer
git show | grep '^+[a-zA-Z0-9]' | cut -c 2- | pbcopy

## append the last 5 commits with the same regex, to some other file
git show -n 5 | grep '^+[a-zA-Z0-9]' | cut -c 2- >>
