3.6 base64: Transform data into printable data
base64 transforms data read from a file, or standard input, into (or from) base64 encoded form. The base64 encoded form uses printable ASCII characters to represent binary data. Synopses:
base64 [option]… [file] base64 --decode [option]… [file]
Example#1: Encoding text data
$ echo 'linuxhint.com' | base64
Example#2: Decoding text data
$ echo 'bGludXhoaW50LmNvbQo=' | base64 --decode
Example#3: Encoding text file
$ base64 sample.txt
$ base64 sample.txt > encodedData.txt $ cat encodedData.txt
Example#4: Decoding text file
$ base64 -d encodedData.txt
$ base64 --decode encodedData.txt > originalData.txt $ cat originalData.txt
