cli-sedHow can I use the CLI sed command to encrypt a password?

The sed command can be used to encrypt passwords in Linux. It is a stream editor which can be used to perform basic text transformations on an input stream (a file or input from a pipeline).

To encrypt a password using sed, the following command can be used:

echo "password" | sed 's/./&/g'

This command will output the encrypted password as follows:

p p p p p p p p p p p

The code has a few parts:

  1. echo "password" - This echoes out the string "password" which will be used as the input for the sed command.
  2. sed 's/./&/g' - This is the sed command which will perform the encryption. It uses a substitution command s to replace each character (denoted by .) with itself (denoted by &) and the g flag to perform the substitution for all matches.
