debugger in bash

  • 772

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

  2. 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.

  3. 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}, $?]
