It works, but almost all UNIX commands that work on pipelines can take a list of files as arguments. Out of the commands I use regularly, "patch" is the only one that works exclusively from stdin, probably because file arguments have a different, somewhat obscure, and probably historical meaning. If appropriate, using files as arguments instead of using shell pipelines is a best practice. Commands can optimize for that use case, print better error messages, etc... And it is not a good thing to encourage useless use of cat. If you goal is to show how your tool is to be used with pipelines, show an actually useful pipeline for example "sed '1b;/abc/!d' file.csv | tv". The "sed" command prints the first line (header), and all lines containing "abc". |
