unzip me pls```
## Solution: 
Attached to the challenge is a password.txt and a file called zip-25000.zip.The zip-25000.zip file is password-encrypted, so you must unlock it with the password contained in password.txtUpon unzipping zip-25000.zip, you will soon figure out that inside the unzipped folder, there is a file called password.txt and zip-24999.zip.This usually means that you'll have to do this process 24999 more times, which, if you do it manually, and assuming you take 5 seconds to unzip one zip file, it would take ~35 hours of nonstop unzipping. 
That's crazy. No one wants to do that. (unless you're crazy)
So obviously you want to make a script to automate it. Some used python to solve it, but I used bash (only because it's simpler)
My thought process was to answer all of the following questions:* How do I automate it?* How do I loop it?* Is there a way to make this process more efficient?
From the questions above, I knew I had to implement these:* Read password, use it on zip* Unzip* Loop 25000 times* Delete the original file (this idea came up later on because I realized it would clog up my storage)
So I made this bash script to help me
```bash#!/bin/bashj=0for i in {1..25000}do    unzip -P $(strings password.txt) -o $(ls *.zip)    rm zip-$((25000-$j)).zip    j=$((j+1))done```
Unzipping all of them gives a flag.txt, which reads:
## Flag:
```TCP1P{1_TH1NK_U_G00D_4T_SCR1PT1N9_botanbell_1s_h3r3^_^}```
## Notes:
I believe this code isn't fully optimized, as it took me ~10 minutes to fully unzip all of them.(i'm still learning)
