How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you

spongeitself doesn't provide the wrapper functionality... But it's also impossible to make a really generic wrapper, because an arbitrary tool might edit the given file in-place itself, and not print to stdout. Using the wrapper with one like that might be problematic. Also there's the question of caching the data to memory vs. to a temporary file, and overwriting the target in-place vs. creating a new file with the same name... (not sure what sponge does)inplace() { "${@:2}" < "$1" | sponge "$1" }inplace() { "${@:2}" < "$1" | sponge -- "$1"; }to deal with arbitrary file paths. Orinplace() (file="${1?}"; shift; <"$file" "$@" | sponge -- "$file")to avoid that ksh93ism. Setting thepipefailoption in there would also be useful to report failure of the command (in any case, the file is lost if the command fails).
