How to Batch Decrypt With GNU GPG

To batch decrypt with GNU GPG (GNU Privacy Guard), you can use a combination of command-line tools and shell scripting. Here's a step-by-step guide:

1. Create a folder where you will place all the encrypted files that you want to decrypt. 2. Open a terminal window and navigate to the folder where you created the encrypted files using the `cd` command. For example, if you created a folder called "encrypted" on your desktop, you can navigate to it by typing `cd ~/Desktop/encrypted`. 3. Create a new text file in the same folder and add the file names of the encrypted files, one per line. For example, if you have two encrypted files named "file1.txt.gpg" and "file2.txt.gpg", your text file should look like this:

``` file1.txt.gpg file2.txt.gpg ```

4. Save the text file and name it something like "encrypted_files.txt". 5. Open a text editor and create a new shell script. For example, you can create a file called "batch_decrypt.sh". 6. In the shell script, add the following code:

```bash

1. !/bin/bash

while read line; do

 echo "Decrypting $line"
 gpg --decrypt "$line"

done < encrypted_files.txt ```

This code will read each line in the "encrypted_files.txt" file and decrypt the corresponding file using the `gpg --decrypt` command. The `echo` command will print the name of the file that is being decrypted for each iteration of the loop.

7. Save the shell script and make it executable by running the following command:

``` chmod +x batch_decrypt.sh ```

8. Run the shell script by typing `./batch_decrypt.sh` in the terminal window. This will start the decryption process for each file listed in the "encrypted_files.txt" file.

9. Once the script has finished running, you should find the decrypted files in the same folder where the encrypted files were located.
