0 0 2-31 * sun /home/ubuntu/x.h
0 0 2-31 * mon-sat /home/ubuntu/y.h
This ends up running both of them. Am I doing something wrong here?
This is the crontab format:
* * * * *
| | | | |
| | | | +---- Day of the Week (range: 0-6, 0 standing for Sunday)
| | | +------ Month of the Year (range: 1-12)
| | +-------- Day of the Month (range: 1-31)
| +---------- Hour (range: 0-23)
+------------ Minute (range: 0-59)
Ubuntu man 5 crontab says:
field allowed values
----- --------------
minute 0-59
hour 0-23
day of month 1-31
month 1-12 (or names, see below)
day of week 0-7 (0 or 7 is Sun, or use names)
So, this should work for you:
0 0 2-31 * 0 /home/ubuntu/x.h
0 0 2-31 * 1-6 /home/ubuntu/y.h
I'm not sure why 7 would run on Saturday--is your system time accurate and in the right timezone?
Edit: Ah, yes, unfortunately you cannot specify both the day of the week and the day of the month. From man 5 crontab:
Note: The day of a command's execution can be specified by two fields — day of month, and day of week. If both fields are restricted (i.e., aren't *), the command will be run when either field matches the current time. For example, ``30 4 1,15 * 5'' would cause a command to be run at 4:30 am on the 1st and 15th of each month, plus every Friday. One can, however, achieve the desired result by adding a test to the command (see the last example in EXAMPLE CRON FILE below).
So, the answer is:
0 0 2-31 * * test $(date +\%u) -eq 7 && /home/ubuntu/x.h
0 0 2-31 * * test $(date +\%u) -ne 7 && /home/ubuntu/y.h
$(date '+%u') returns 1-7 representing Monday thru Sunday. Try echo $(date '+%u') for an example.
