I'm trying to figure out how to use cal command on Linux/Debian to display Monday as the first day of the week instead of Sunday.
From what I see accordingly to cal's man page
-M Weeks start on Monday.
But it doesn't seem to work on my machine:
cal -M
Usage: cal [general options] [-jy] [[month] year]
cal [general options] [-j] [-m month] [year]
ncal -C [general options] [-jy] [[month] year]
ncal -C [general options] [-j] [-m month] [year]
ncal [general options] [-bhJjpwySM] [-H yyyy-mm-dd] [-s country_code] [-W number of days] [[month] year]
ncal [general options] [-Jeo] [year]
General options: [-31] [-A months] [-B months] [-d yyyy-mm]
CodePudding user response：
cal doesn't support -M option in all UNIX versions.
Alternatively, you can use ncal -M -b to get the desired output.
