These special characters may be used to enhance user credential security. However, in order for these characters to be properly
interpreted, you must use one of the following methods:
∙
Escape each instance of the special character by preceding it with the escape character (
\
).
∙
Enclose the credentials containing special characters within single quotes (
'
).
If single quotes are themselves part of the credential, precede each instance of the single quote with the escape character (
\
).
Alternately, the string may be enclosed in double quotes (
"
) if a more intricate bash substitution is desired to further strengthen
the security measure of the credentials.
You can test the representation of the credentials by logging in with root-level permissions and using the
echo
command.
