sed -i ''; Linux GNU sed usessed -i.
sed -i 's/old/new/g' file.txt # replace all occurrences
sed -i '/pattern/s/old/new/g' file.txt # replace on matching lines only
sed -i '/pattern/d' file.txt # delete matching lines
sed -i '5d' file.txt # delete line 5
sed -i '10,20d' file.txt # delete lines 10-20
sed -i '/pattern/a\new line' file.txt # insert after match
sed -i '/pattern/i\new line' file.txt # insert before match
sed -i '1i\new first line' file.txt # prepend
echo 'content' >> file.txt # append
sed -n '5,10p' file.txt # extract lines 5-10
awk -F',' '{print $2}' file.txt # print 2nd CSV field
grep '^def ' main.py | sed 's/def //;s/(.*//' # extract function names
