Is there any way to debug bash script without using echo and logging?

I'm talking about using breakpoints and stuff like that.

Yes there is Bash Debugger Project.

You can also use set -x and set-v at execution. HERE and HERE or HERE is some info on that.

There several different ways, i.e.:

  • Run your script with the -x option

    bash -x yourscript.sh
    
  • Add set -x in a new line at the beginning of your scriptfile after the Shebang #!/bin/bash and before the beginning of your script, set -v would display the shell input lines, set -x displays the executed commands and arguments

  • replace the shebang of your script file with #!/bin/bash -xv
