From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

zcat shouldn't error out if you try to zcat an uncompressed file, it should just output the damned file ! (lemmy.ml)

Well in this particular case, zcat failing with error on uncompressed text isn't a behaviour worth preserving.

It should do the expected zcat behaviour, which is just print the text.

I have a hard time imagining a scenario where you call zcat and would prefer an error rather than a useable output

I already expressed that quickly getting an exit status that isn't 0 after an issue is encountered is probably useful.

I can imagine that someone would find a program like this to be useful, and depends on the presently common behavior of zcat, so I expect this is an important part of a system used by a corporation I interact with (and probably many more than I'd expect):

if
    zcat ./file.txt.gz >/dev/null
then
    process_file ./file.txt.gz
else
    printf '%s\n' "There was a decimal exit status of ${?}"
fi

A failure to understand whether something is useful is not a good reason to change it.
