exit from all nested shell script

[marhuum]

How to exit from all nested shell script calls once in a single command?
..and if any way how to exit some number of nest calls times ?

Can you run your sub-scripts as 'source' instead of 'bash' ?

If not, you could call the sub-scripts like this:

bash b.bash || exit

And exit with an error from the sub-script:

exit 1

If necessary, you could exit with a specific error code and test for it.
