#TIL: #xargs has an option -a to read items from a file instead of from standard input. This is perfect if you need to run xargs without a surrounding shell to provide the commonly used pipe mechanism, e.g. calling it just via exec() or similar.

My case today was with Perl's Test::Command::Simple::run_ok() in pxzgrep's TAP based test suite.

If you're a #Linux person and using the command "ps" with options like "aux" instead of e.g. "-e" (i.e. options without leading "-"), you likely learned the #Unix #commandline on #BSD or maybe SunOS 🧔. (Or by someone who grew up with them. 🙂)

In other news: #TIL that (in either variant) the option "j" (e.g. as "ps ajx" or "ps -ej") also shows the PPID (parent PID, only with BSD style options), PGID (process group ID) und SID (session ID).

#cli #commandlinemagic #ps #shellscripting

Did you know that there is a Linux/Unix command that can tell you which lines are in one text file but not in another? Or which lines are common to both files?

Enter the "comm" command. How amazing is that?!
