cron entry via remote ssh

sunlinux · 10-31-2011, 02:10 AM

I want to push a line/entry in cron file (via remote ssh) to execute a script(one time) after 30 second of ssh login/exit.

and it must be deleted(cron line) after running the script automatically .

any guidance is appreciated .

For one-shot scripts a better tool is the at scheduler (provided the at daemon is active on the remote machine). You can do:

Code:

$ at now + 1 minute
at> your_command_here
at> <Ctrl-D>

Anyway, both at and cron have a time granularity of 1 minute, this means you cannot execute something automatically just after 30 seconds you logged-in. Please, can you provide some more details about what you're trying to achieve?
