At the moment I call date this way:
date '+%Y %m %d'
# ==> 2017 12 01
How should I adjust it so that it return a month in the 3-char format? Like this:
date '+%Y %m %d'
# ==> 2017 dec 01

Try: date '+%Y %b %d' | tr A-Z a-z

Or you may use the translate command (`tr`) with character sets like `tr '[:upper:]' '[:lower:]'`. See `man tr` for more information. – U880D Aug 08 '18 at 10:56
