Do you know Bash & csh shell likes carrots ?

Scenario:

When we try to execute a command at the shell, we make mistakes like missing out a character or misspell it. Do you know you can correct them without having to type the command again or taking the history and changing them ? See the following example to understand the use of bash shell caret!

# find . -naem “*.php” -exec chmod 644 {} \;
find: invalid predicate `-naem’

This is when carrots comes to help. Issue this command in the shell and you will get the results.

# ^em^me^
find . -name “*.php” -exec chmod 644 {} \;

If you just execute the command without a proper history to replace, it will display,

bash: :s^em^me^: substitution failed
