Run the command directly without the alias in bash - suppress alias substitution

Use a “\” (backslash) before the command to run it without the alias. The backslash escape character can be used before a shell command to override any aliases. For example if rm was made into an alias for rm -i then typing “rm” would actually run rm -i.

The (Bourne/POSIX) shell specification says that alias substitution in an interactive shell is suppressed when any character of the command word is quoted. A backslash is one way to do that, but there are also other well known ways to quote: single and double quotes. All of the following will suppress alias substitution:

\curl
cur\l
\c\u\r\l
"c"url
"curl"
"c""u""r""l"
'curl'
'cu'"rl"

Using \curl is just the most common and readable way.
