debugger in bash

Question

I use

sh -xv my_script.sh

to debug the /bin/sh script. How do I debug /bin/bash scripts?

I am getting the following error and I need to know the line that needs to edit.

# ./batch_master.sh

'@'10.10.10.10.' (using password: NO)user 'companycuser

Doesn't this work?

bash -x ./batchmaster_sh

	It does work. But shows a lot of junk. I want to know only the mysql command that does not work. I do not see that anywhere in the output. The output is much lengthy than expected. – shantanuo Sep 2 '11 at 10:01
	Well... what happens if you `grep 10.10.10.10 ./batch_master.sh` or `grep mysql ./batch_master.sh` :) – Janne Pikkarainen Sep 2 '11 at 10:35

Edit the script, add a -x option to the shell command line like:

#!/bin/sh -x

or

#!/bin/bash -x

It will print all executed commands and you can see what is done after what.
