Bash : If command timeout, execute something else

I am doing the following :

timeout 180 bash myscript.txt

myscript.txt is supposed to be fully executed in less than 180 seconds. IF NOT, I want emergencyscript.txt to be executed. Is it possible to do so ?

Like

timeout 180 [bash myscript.txt] [bash emergencyscript.txt]

#!/bin/bash
if ! timeout 180s bash myscript.txt; then bash emergencyscript.txt; fi

maybe try checking to see if timeout failed or not?

timeout 180 bash myscript.txt
if [ $? -ne 0 ]
then
#....do stuff....
fi

That's dependent on timeout or the script giving a non-zero exit value if it takes too long though.

The exit status of timeout is 124 if the command times out. You can test for this explicitly.

timeout 180 bash myscript.txt
exit_status=$?
if [[ $exit_status -eq 124 ]]; then
    bash emergencyscript.txt
fi

Any other value for exit_status is the result of myscript.txt running to completion.
