base64

write a commented code to convert data64 data into ascii in the terminal
Here is a script that can be used to convert base64 data to ASCII in the terminal:

Copy code
#!/bin/bash

# Check if input is provided
if [ $# -eq 0 ]; then
    echo "No arguments provided"
    exit 1
fi

# Check if base64 command is available
if ! command -v base64 &> /dev/null; then
    echo "base64 command not found"
    exit 1
fi

# Convert base64 data to ASCII
echo "$1" | base64 --decode
This script first checks if any input was provided, and exits if none was provided. It then checks if the base64 command is available, and exits if it is not. Finally, it uses the base64 command to decode the base64 data and prints the resulting ASCII output to the terminal.

To use this script, save it to a file and make it executable with chmod +x <filename>. Then, run it with ./<filename> <base64 data>, where <base64 data> is the base64 data you want to convert to ASCII.

For example:

Copy code
./convert.sh SGVsbG8sIHRoaXMgaXMgYSB0ZXN0
This will print "Hello, this is a test" to the terminal.

I hope this helps! Let me know if you have any questions.
