Find Last command name within a shell script

[Sangal-Arun]

How can I get to know what command/script/function, I just called/ran within a script.

[stpuser@stpbuild]$ echo aaa
aaa
[stpuser@stpbuild]$ echo bbb
bbb
[stpuser@stpbuild]$ echo ccc
ccc
[stpuser@stpbuild]$ history|tail -1
34      echo ccc


[stpuser@stpbuild]$ cat a.sh
echo aaa
echo bbb
echo ccc
history |tail -1
[stpuser@stpbuild]$ ./a.sh
aaa
bbb
ccc
[stpuser@stpbuild]$ . ./a.sh
aaa
bbb
ccc
37      ./a.sh
[stpuser@stpbuild]$

What I want is that, a.sh should display "echo ccc" as it is the last command that was executed before the last command in a.sh script.

Any helps!

This does not exactly answer your question, but if you use "history 2" it will give you something close.

history: usage: history [-c] [-d offset] [n] or history -awrn [filename] or history -ps arg [arg...]

$LINENO can be useful (if we embed that in our script line) provided, there should not be multiple commands (separated by ";" semi-colon) in one line.
