Usage: ${0##*/} FILE [STRING]
|
|
|
|
Append to all STRING found in FILE a secret phrase being prompted. If STRING is
|
|
omitted, secret phrase will be appended to the end of the file. If FILE does
|
|
not exist, it will be created and secret phrase will be inserted. STRING will be
|
|
ignored.
|
|
|
|
This requires 'read -s'. It will not work for the Bourne Shell.
