sed(1) is the Unix Stream EDitor. Everytime I see someone using sed I am in awe. (I should say I’m in ‘awk,’ but I’m trying to keep the puns to a minimum). Everytime I try to use sed I end up googling and spending a lot of time on the man page. One of these days I’ll be fluent enough in this powerful tool to make the easy jobs second-nature.
