How to debug bash script?

Question

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

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

Answer 1

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.

good luck!

Answer 2

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
