This was removed in commit af7c483 due a mailing list comment: https://marc.info/?l=util-linux-ng&m=138116560906549&w=2 It's generally best to avoid optional args on short args, as in this case -w3 is ambiguous and -wj is problematic. So I'd instead support an interface like -w,--week[=NUM] cal -wj cal: invalid week argument: 'j' cal -w3 January 2018 Su Mo Tu We Th Fr Sa 1 1 2 3 4 5 6 2 7 8 9 10 11 12 13 3 14 15 16 17 18 19 20 4 21 22 23 24 25 26 27 5 28 29 30 31 That should be an expected result for those commands. Util-linux has many commands with optional args for short options: ipcrm, swapon, lscpu, nsenter, dmesg, script, cfdisk, fdisk, hexdump It seems unexpected to have an argument for long options only. I found this because I tried to pass an argument to -w.
