Right-Click File Hash Check - Linux Mint

Here’s how you can integrate a file hash check script into the right-click menu in Linux Mint:

1. Create the File Hash Script

1. Create the script (/usr/local/bin/hash-check.sh):

   sudo nano /usr/local/bin/hash-check.sh
   

2. Paste the script below and save it:

   #!/bin/bash
   
   # Get file path from the context menu
   file="$1"
   
   # Check if file exists
   if [ ! -f "$file" ]; then
     echo "File not found!"
     exit 1
   fi
   
   # Choose algorithm
   echo "Choose a hash algorithm:"
   echo "1) SHA1"
   echo "2) SHA256"
   echo "3) SHA384"
   echo "4) SHA512"
   echo "5) MD5"
   echo "6) Show all"
   
   read -p "Enter choice [1-7]: " choice
   
   case $choice in
     1)
       sha1sum "$file"
       ;;
     2)
       sha256sum "$file"
       ;;
     3)
       sha384sum "$file"
       ;;
     4)
       sha512sum "$file"
       ;;
     5)
       md5sum "$file"
       ;;
     6)
       echo "SHA1:"
       sha1sum "$file"
       echo "SHA256:"
       sha256sum "$file"
       echo "SHA384:"
       sha384sum "$file"
       echo "SHA512:"
       sha512sum "$file"
       echo "MD5:"
       md5sum "$file"
       ;;
     *)
       echo "Invalid choice! Press Enter to quit dumbass"
       ;;
   esac
   

3. Make the script executable:

   sudo chmod +x /usr/local/bin/hash-check.sh
   

   You can also verify the permissions with:

    ls -l /usr/local/bin/hash-check.sh
   

   You should see something like this for the file:

    -rwxr-xr-x 1 root root ... /usr/local/bin/hash-check.sh
   

   The x means it’s executable.

2. Create Nemo Action for Mint

Nemo supports custom actions through the .nemo_action file. You can define the right-click menu item for your hash-check script like this:

1. Create a custom action file in the Nemo actions folder:

   mkdir -p ~/.local/share/nemo/actions
   nano ~/.local/share/nemo/actions/hash-check.nemo_action
   

2. Add the following content to the file:

   [Nemo Action]
   Name=Check File Hash
   Comment=Calculate file hash (MD5, SHA1, SHA256, etc.)
   Exec=/usr/local/bin/hash-check.sh %F
   Icon=utilities-terminal
   Selection=Any
   Extensions=any;
   Terminal=true
   

   • Exec=/usr/local/bin/hash-check.sh %F: This will pass the selected file(s) to the hash-check script.
   • Terminal=true: Ensures that it opens in a terminal window so you can see the output.

3. Save and close the file.

3. Testing File Hash Script

1. Restart Nemo to apply the new action:

   nemo --quit
   

2. Right-click a file in Nemo, and you should see a new menu option called “Check File Hash”. Selecting it will run the hash-check script, allowing you to choose the algorithm and see the results in the terminal.

ChatGPT can be credited for this script. I only made a few minor changes.
