bin: `after-do` to run a command after time or existing pid

bew opened this issue · comments

after-do --pid 1234 -- echo bar
after-do --at 'now + 5m' -- echo bar

FIXME: as a bin? or as a shell function? (start with the shell function?)

I got inspired when reading the existence of the at command in https://www.linuxjournal.com/article/1189 (in the 2nd half).

and maybe the --pid variant could be useful to wait for an already running process and do sth after it!
(might need to use 1s polling)
