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 142 weeks and 6 days 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 142 weeks and 1 day 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.
