This article will explain in detail about using linux's builtin command to execute bash built-in commands. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The builtin command is used to execute the specified bash built-in command, and the bash built-in command called by the builtin command takes precedence over the external command with the same name and the shell function with the same name. Returns the return value executed by the built-in command, unless the built-in command is not passed or is disabled.

Syntax format: builtin [parameters]

Common parameters:

The bash built-in command to be called by shell-builtin arg passes one or more parameters to the bash built-in command

Reference example

Priority order in the case of the same name: builtin built-in commands > functions > built-in commands > external commands:

[root@linuxcool ~] # echo "the Great Wall" [root@linuxcool ~] # type-t echo [root@linuxcool ~] # echo () {printf "123\ n"} [root@linuxcool ~] # echo [root@linuxcool ~] # type-t echo [root@linuxcool ~] # builtin echo-e "backslash\"

Execute the shell internal instructions and output the command aliases under the current system:

[root@linuxcool ~] # builtin alias [root@linuxcool ~] # alias cp='cp-I'[root@linuxcool ~] # alias l.='ls-d. *-- color=tty' [root@linuxcool ~] # alias ll='ls-l-color=tty' [root@linuxcool ~] # alias ls='ls-- color=tty' [root@linuxcool ~] # alias mv='mv-I'[root@linuxcool ~] # alias rm='rm-i' [root@linuxcool ~] # alias which= 'alias | / usr/bin/which-- tty-only-- read-alias-- show-dot-- show-tilde' about using the builtin command of linux to execute bash built-in commands is here. I hope the above content can be of some help to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
