Is it possible to debug bash scripts line-by-line?

Question

I'll love something like Microsoft Visual Studio's line-by-line debugging in bash, with current variables values and so.

Is there any tool or way to do it? set -x and set -v are nice but not perfect.

see http://stackoverflow.com/questions/951336/how-to-debug-a-bash-script — Piccolo, Feb 15 '13 at 06:24
Already seen. Doesn't covers line-by-line debugging, which is the whole point here. I've already searched alot and found nothing, which is why I came to SO. — emi, Feb 15 '13 at 06:26
No, the `set -x` (and `-n` and `-v`) options are basically what's available. — Jonathan Leffler, Feb 15 '13 at 06:41
The linked question also refers [Bash Debugger](http://bashdb.sourceforge.net/) which is what you are looking for. — bsravanin, Feb 28 '13 at 15:21

See bashdb.

If it's installed on your system, see man bashdb.

If you are on a Mac (like I was) then you might need to install the GNU version of Bash.

I did that using "MacPorts" http://www.macports.org/

Once you have MacPorts...

port install bash

Then follow the instructions to

./configure (in bashdb unpacked directory)

make

sudo make install

Then add the folder where bashdb can be found in your PATH
