man tmpwatch
The flags=-umc is explained in man page
...
If the --atime, --ctime or --mtime options are used in combination
...
The *-unix are excluded because they are e.g. X related (UNIX sockets)
$ netstat -a | grep -i .X11-unix
$ ls -al /tmp/
$ ls -al /tmp/.X11-unix/
I you want to run your own tmpwatch cron job with your changes:
- create your version of /etc/cron.daily/tmpwatch somwhere that will not
be overwritten (e.g. your home dir $HOME/cron.daily/tmpwatch)
e.g.
change to 1d instead of 30d where appropriate according to tmpwatch format.
- add or create or modify a crontab file for a user to be run by cron
cron(1), crontab(1)
# ls -l /var/spool/cron
# crontab -u jb -e
< edit it by adding a job; see examples in crontab(5), e.g.
SHELL=/bin/sh
MAILTO=root
# run five minutes after midnight, every day
5 0 * * * $HOME/cron.daily/tmpwatch
