Does sed allow in-place file replacement, or do you need to redirect to a different file then cp/mv it over the original? I haven't used it in many years, but sed didn't used to allow this.
- derwiki 15y agosed -i 's/old/new/g' file

For other commands, if it's a big file, I will just pipe through less (still no temp file) and then save the buffer (to overwrite the original file), instead of using this hack. A hack for in-place editing, for old school sed (no -i): sedi(){ case $# in 0) echo usage: sedi cmds file;; 2) sed -an ' '"$1"'; H; $!d; g; w '"$2"'' $2;; esac; }
