Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Saves all the "cut" hacks

echo -e "12 morning\n15 afternoon\n24 evening" |awk '{if ('`date +%H`'<$1) {print "Good "$2;exit}}'
echo -e "12 morning\n15 afternoon\n24 evening" | awk '{if ('`date +%H`' < $1) print "Good " $2}'

Know a better way?

If you can do better, submit your command here.

What others think

It's better to use i=`date +%H`. No need for cut. There's also elif instead of "else if".

Does the date output depend on the environ?

Comment by kaedenn 395 weeks ago

@kaedenn: Yes, in general, see LC_TIME (setlocale) and the strftime manual pages. But %H is independent of the locale; it always expands to the hours as a two-digits number using a 24-hours clock (this is straight from the tm_hour element of a struct tm in C, see ). This is specified by the C90 and SUS/POSIX standards.

Comment by inof 394 weeks and 3 days ago

Sorry, the web page accidentally removed the angle brackets ... I wrote "struct tm in C, see [time.h])" with angle brackets instead of square brackets.
