Convert Text File Strings into Base64 encoding
Last Updated : 21 Apr, 2022
In the Linux system, you have a command base64. This helps you to convert text into base64 encoding but how can you change multiple lines of text into base64 encoding. We will understand some common Linux command in this article. That helps us to solve our problems. We will discuss piping, echo, and how to get user input from the keyboard.
Example:
Echo Command
In Linux System, you have an echo command that printing strings and numerical values in the terminal
echo "Your String"
Example:
Encoding and Decoding Text
Syntax base64:
base64 options filename
Convert Text into base64 encoding
echo Team | base64
Output
Decode base64 text into plain text
echo base64_text | base64 -d
Output:
Encoding Text File into base64 encoding
Use this Syntax:
base64 filename
Output:
Encoding Text file Decoding base64 File into plain Text
base64 -d filename
Encoding any user Defined Text
First, we create a shell script for this task read input from users, and convert text into base64 encoding
Use this Shell Script
#! bin/bash echo Enter you Text read data output=`echo -n $data | base64` echo "Encoding Data $output"
Piping
Piping is reading input from one command and serving to another command. Now let's Combine all of these commands and solve our problem. Suppose, we have a text file name of the file name.txt
Example:
$ cat names.txt Ahmedabad Taj Mahal India Gate Qutub Minar
So we can change these strings to base64 encoding in following way:-
cat names.txt | while read names do; echo $names | base64 ; done
Output:
