Have you ever typed a command and rushed to hit\u00a0Enter<\/strong>, only to find that you had a typo in it? While you can use the\u00a0up<\/code>\u00a0and\u00a0down<\/code>\u00a0arrows to navigate the\u00a0command history<\/a>\u00a0and edit the typo, there\u2019s an easier and faster way.<\/p>\n

Don\u2019t Miss:<\/b>\u00a0The Power of Linux \u201cHistory Command\u201d in Bash Shell<\/a><\/p>\n

In this tip, we shall cover a simple and handy method of dealing with a command line typo, let\u2019s suppose you wanted to see if there\u2019s a service listening on port\u00a022<\/strong>, but accidentally typed\u00a0nestat<\/code>\u00a0instead of\u00a0netstat<\/code>.<\/p>\n

You can easily replace the typo with the correct command and execute it like so:<\/p>\n

# nestat -npltu | grep 22\r\n# ^nestat^netstat\r\n<\/pre>\n
That\u2019s right. Using two\u00a0carat<\/strong>\u00a0signs (they should be followed by the typo and the right word, respectively) you can correct the typo and run the command automatically afterwards.<\/p>\n
