Tootsie Pop - 150

How many licks does it take to get to the center of a tootsie pop?

👉 So, a zip file huh? let's check it out.

clearly, this is a deeply compressed file. Also as a scripting challenge, this must be much deeper. Further, as we can see in first decompression, the extension or type of compression differs. So, let's do some hit and trial to find different kind of compression used.

Now, the problem statement is:

• [ ] check if the file is a compressed file.
• [ ] if yes, find type of compression used, else exit.
• [ ] check if the file has extensions → if not add it.
• [ ] Decompress compressed file with suitable tool.
• [ ] Remove previous files to prevent any issues.

Hence, The steps to overcome the problems are:

• [ ] file command in bash is handy to determine if a file is a compressed one.
• [ ] Piping file command with cut can give type of compression used.
• [ ] Regex to check if the decompressed file has any known extension.
• [ ] Hit and trial along the loop, for various tools for corresponding extension or compression type.
• [ ] Create a hidden folder to move the previous file in it. Further, hide the script. This is done to ease us with finding the resulting decompressed file with ls command.

Hence, now following the algorithm, the resulting script is:
