unzip many files with different passwords and compression formats with bash script

Question

I have this bash script to unzip files with different passwords. But it decompresses indefinitely and damages the decompressed files

PASS="passfoo passbar passfoobar"
LIST=$(ls -1 *.{zip,7z,7z.001,rar})
for password in $PASS; do
  OIFS="$IFS"
  IFS=$'\n'
  for i in $LIST
  do
      echo "$password"
      7z x -y -p"$password" "$i" -aoa
      if [ $? -eq 0 ]; then
     continue
    fi
   done
   IFS="$OIFS"
  done

To temporarily fix it I have had to create a loop for each password.

What I want is that when the script matches a password, the script won't test the others, and if there is no match with any password that tries to decompress it normally (if it does not have a password) or that shows an error (if the file has a password but it is not in the variable) without stopping to decompress the other files. Thk

PD: Keep in mind that files to decompress sometimes come with names with space and other non-ASCII characters, or are files compressed by parts

Answer 1

Not sure if the continue is the correct action inside the inner loop but I have adjusted your code to this.

#!/usr/bin/env bash

shopt -s extglob nullglob

passw=(
  passfoo
  passbar
  passfoobar
  banana
  chocolate
  whiskey
  vodka
  icecream
)

for f in *.@(zip|7z|7z.001|rar); do
  for p in "${passw[@]}"; do
    if 7z x -y -p"$p" "$f" -aoa; then
      break
    fi
  done
done

• the shopt -s enables the shell options that are not enabled by default, shopt -u to disable the options.

• extglob a feature that let's you do the *.@(zip|7z|rar) to match different file extensions. which expands to *.zip *.7z and *.rar and expands to all the files in the directory that ends in that particular extension (if there are files) not sure about the order though.

• nullglob If there are no files ending in the pattern *.@(zip|7z|rar) nothing will be evaluated so it will be empty, if not enabled the glob will expand to a literal *.rar or *.7z or *.zip which will cause an error to your script.

Edit: As per the OP's @ajcg , I have change the continue to break so it works as expected.
