Probably something you'd catch pretty quickly, but still.
- dpcx 6y agoAs does Python, which drives me crazy. -V is version on Python.
- MaxBarraclough 6y agoVery annoying. Java HotSpot uses -version, rather than --version, which is even worse. Don't mess with the standard long-form flag!
- hackerm0nkey 6y agoI get it wrong every damn time. 16 years and counting.
- iforgotpassword 6y agoSame! Somehow I also start confusing this with somewhat related tools like gcc. It's rare enough that I need to query these that it's all blurry in my memory again by next time. "huh I guess gcc was that goofy one with just one dash.." Nope.
- LukeShu 6y agoTo be fair, the JVM predates GNU-style --long flags being "standard". Lots of older programs use "X11-style" -long flags (that many pre-X11 programs used, like `find`).

- tannhaeuser 6y agoLong flags are a GNUism, not a "standard" by any means. The closest that comes to a standard in this space are POSIX utility conventions [1].

- jjgreen 6y ago... and it wrote the version to stderr up to 3.3, the stdout from 3.4; very convenient if you need to switch on version (which you do).
- nostoc 6y agoThere's so much variation in flags for version, I've taken the habit of always using the long `--version` flag.
- ben509 6y agoThe worst (well known) offender is grep -v meaning grep --invert-match just for the sheer bafflement of "verbose" now hiding what you were looking for.
- u801e 6y agoThat actually comes from ed and vi. The g command would search for a line that matches a given regular expression and run the following command on that line. The v command was the inverse (search for lines that don't match the given regular expression). The default command was to just print the line. Hence the name grep g/re/p
- EE84M3i 6y agoWow, that's funny, I normally expect '-v' to be verbose, but maybe I just use a lot of `tar` and `curl`!
- mjochim 6y agoOr maybe cp, or rm, or rsync, or mount, or wget, or netcat (both gnu and bsd) ... it’s really pretty reasonable to expect -v to mean verbose ;-).
