Wrench How to reverse compiled bash (obfucation)?

hi guys,
10 years a go I wrote an script in bash programming and I compiled (obfuscate) it, but after 10 years I need to change some lines and remove some lines, but i do not remember what I've done.
does anyone has any idea about decompile (deobfuscation) it?

here is some line of my code (u are not seeing any omitted):

Obfuscation sample - Free Image Hosting


BTW, I used ltrace and strace but I do not familiar with these commands and how to change it?

tnx in advance guys

Do you remember which utility was used to obfuscate the code?

Kindly note that compiling source code into an executable is not a revertable process. By compiling something into an executable information is stripped from the whole and one needs to provide this information to "decompile" it.

That means: you can "decompile" soemthing but it will always be a "best effort" and you will not get back the source code you started with.

The things you won't get back (because they are stripped away by the compiler - any compiler) are:
  • comments of any sorts (not necessary to run the code and therefore stripped)
  • "speaking" names for variables, functions, ....
  • "source code formatting of any kind

I hope this helps.
