comment Shall I save my crontab file in /tmp?
ok, well, poke around. check your man page for your cron implementation or documentation for your distro. i don't have magic answers for you; this kind of thing is not universal.

crontabs are per user. to verify that your cronjob runs, you can check the cron logs. typically in /var/log/cron.log, but it could be other locations as well.

if you log out, nothing will happen to your crontab. it doesn't live in /tmp.

comment Shall I save my crontab file in /tmp?
your actual crontab lives somewhere in /var/spool (typically), but you should never touch your actual crontab and you should never need to, either - use crontab -e instead. You probably don't have the right access level to edit the raw crontab file anyway.

comment Create symlink tree in existing directories
any insight into why it's necessary to specify workdir in more recent kernels? the kernel docs only say The "workdir" needs to be an empty directory on the same filesystem as upperdir. there's no mention of what workdir is for or why it's necessary to provide it.

comment Substitute all occurrences of pattern with first matched group
Thanks for the infor, @mikeserv. I can tell you're right because this fails with the --posix flag to sed. But I don't understand why - the sed man page doesn't do much to explain the non-posix features of GNU sed.
