    @don_crissti I'll never understand why people prefer random web documentation to the documentation installed on their systems (which has the added benefit of actually being relevant to their system). Commented Nov 17, 2017 at 9:53

    @Kusalananda - Well, I can think of one scenario in which people would include a link to a web page instead of a quote from the documentation installed on their system: they're not on a linux machine at the time of writing the post... However, the link should point (imo) to the official docs (hence my comment above, which, for some unknown reason, was deleted by the mods...). That aside, I fully agree with you: the OP should consult the manual page installed on their system. Commented Nov 17, 2017 at 12:52

    @don_crissti Or they are on a server that has no manpages installed which is rather frequent. Commented Feb 15, 2018 at 12:10

    @don_crissti I can think of several reasons. For starters, man pages are usually written with every feature explained, in whatever order makes sense to the programmer. That's not usually helpful at all to normal users. I've been scripting for 35 years, and these days I search stackexchange first, then worst-case (almost never) fall back to man page.

    I should also add that, in addition to overwhelming and often inscrutable output of man pages for relatively inexperienced users, as a programmer/power user I'm usually looking for novel solutions that man pages don't cover. For example (just now), specific date format for 'find' command output. The man page doesn't tell you to put "%T" in front of each variable--at least not that I found even looking for that specifically. You could spend all day trying to figuring it out. (Or just give.) Whereas a search on Stack Exchange will yield that answer, clearly explained, in the first result. Commented Oct 26, 2018 at 15:24
