I need to stop execution of a running java script in terminal and start the same execution at every x interval of time in terminal. Is it possible?
/usr/bin/timeout is the tool to use. See
man timeout. Here is an example, from one of my nightly
cron jobs, you can wrap yours in a
while true ; do loop:
TO_KILL="45m" # timeout (kill -KILL) for hpodder TO_HUP="42m" # timeout (kill -HUP) for hpodder. Makes sense only if it is less than $TO_KILL # ... timeout -k $TO_KILL -s HUP $TO_HUP hpodder update
This will run the
hpodder update until it finishes, or 42 minutes have passed, when it will be sent (see
man 7 signal) a
HUP signal. If
hpodder update is still running after 45 minutes (3 minutes after the
HUP was sent), it will be sent the uncatchable
KILL signal, and will be terminated.
