I have some users who I want to "schedule" a specific job for which gets executed on their user account. For some of them, it will be twice a day, for others just once a month. It should happen at logout time. The intended mechanism to do so is ~/.logout, the C shell's logout script. Example: The user quits his work (shell "exit" or ending a custom program that is executed by the shell), now the ~/.logout shoult be executed, e. g. copying his current datasets to "immediate backup" (or other means of processing). I assume I cannot use this approach when the user runs his specific program _as_ the shell (per /etc/passwd), but that's not a problem now, as it's easier to give a regular shell and use ~/.login to "auto-exec" the user-specific program). My question is: As users connect to the system per SSH, how much time will the "at logout time" process have to finish work, or does it work _any_ time after the user has (1st) logged out and (2nd) terminated SSH connection (e. g. disconnect from SSH CLI client or PuTTY)? Will such a ~/.logout job finish even if the user closes his connection right after logout? And just in case a user does not properly log out (e. g. closes PuTTY right from the open session, maybe from within the program or shell he currently runs), will this cause ~/.logout to be processed, or will it be a "stale connection"? -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
