Encrypt every item inside a folder in Bash

I have a code which is supposed to encrypt every file within a folder but when I put it (the encryption code) within the infinite loop it does not work.

touch Out_file.txt
ls > Out_file.txt
i = 0
while:
i = i + 1
line=$(head -n $i Out_file.txt)
openssl cbc -aes-256-cbc -pass pass:Hello123  -p -in $line -out $line.enc
done

It might be able to encrypt all your files within the folder you are running the program in so please proceed with caution

Solution

  • How about:

    (just simplifying how we generate the list of files and run through them)

    
touch Out_file.txt
#write only filename to Out_file.txt
ls -l | awk 'NF>1{print $NF}' > Out_file.txt
while read filename; do
  openssl cbc -aes-256-cbc -pass pass:Hello123  -p -in $filename -out $filename.enc
done <Out_file.txt

    Good Luck.
