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.

  • Thanks for your inputs. The problem got solved after running dos2unix command on the properties file. – shantanuo Sep 2 '11 at 10:18

There has been a debugger for bash around for a since the turn of the century. See http://bashdb.sourceforge.net/

If you are going to use set -x tracing I recommend setting PS4 to:

 PS4='(${BASH_SOURCE}:${LINENO}): ${FUNCNAME[0]} -  [${SHLVL},${BASH_SUBSHELL}, $?]
