Editor to share with you what is the use of the shopt command in Linux. I hope you will get something after reading this article. Let's discuss it together.

Linux common commands shopt commands are used to display and set behavior options in shell to enhance the ease of use of shell. The shopt command can display all the shell operation options that can be set without any parameter options.

Shopt displays and sets shell operation options

Syntax shopt (options) (parameters) option-s: activates the specified shell behavior option;-u: turns off the specified shell behavior option. Parameter shell option: specifies the shell option to operate on.

The instance uses the shopt command to display all the shell operation options that can be set, and enter the following command:

Shopt # outputs all shell operation options that can be set, cdable_vars off cdspell off checkhash off checkwinsize on cmdhist on dotglob off execfail off expand_aliases on extdebug off... As shown in the figure, the status of the option "cdspell" is "off", that is, the cd spell check option is turned off. Now, you can turn it on using the shopt command, enter the following command:

When shopt-s cdspell # turns on cd spell checking and executes the above command, the status of this option will change to "on", that is, on. You can use this command to display the shell operation options again, and the output information is as follows:

Cdspell on # enable cdspell option users can check whether the option is enabled successfully by actually executing the cd command.
