I think you're underestimating how frequently some folks do things like: for x in 'seq 1 100'; do echo "something with $x"; done

(Please forgive lack of backticks on my cellphone keyboard) Or many variations, like every line in a file, or result of a command piped to sed or awk and then processed. Init scripts are about the only shell scripts I write anymore, but I use frequently use it from the commandline, typically on remote terminals.
