last script run

Is there a way to get the last script run?

For example, I know I can do echo $? to get the result code and echo $0 inside the script, but how could I tell what script it came from if I chain them together like:

t1.sh && echo $(previous script filename) $? && t2.sh && echo $(previous script filename) $?

t1.sh
echo hello there

t2.sh
echo hello there to you too.

output:

hello there
t1.sh 0
hello there to you too.
t2.sh 0

Try the history command and then filtering the result to grab only the past script information you're seeking.

If you chain them together with '&&', I don't think its possible (I could be wrong).
On the other hand, if you called them from within each other it t1.sh contains a call to t2.sh, then you can check PID, PPID and work your way back up the chain if you want to go further.
Perhaps you could tell us a bit more about what you're trying to achieve and why.
There may be a better way.
