Source command usage

Problem: After the language is changed, the system prompts that the content of locale cannot be changed every time you log on. (Probably: cannot change locale (gb2312 ))

According to the similar questions on the internetArticleAccording to the method, I found that it is useless here.

Solution:

Modify ~ /. Bashrc File

Then source ~ /. Bashrc

 

Note:

Locale

A language environment defined based on the language used by computer users, the country or region where the computer is located, and the local cultural traditions when the software is running.

 

Source command usage:Source filename: Reads and executes the command in filename in the current bash environment. Note: This command is usually replaced by the "." command. For example, source. bash_rc and. bash_rc are equivalent.Note:

The difference between the source command and shell scripts is,Source executes the command in the current bash environment, and scripts starts a sub-shell to execute the command. In this way, if you write the commands for setting environment variables (or alias) into scripts, it will only affect the sub-shell and cannot change the current bash. Therefore, through the file (command column) when setting environment variables, use the source command.

The source command (from the C shell) is the built-in command of the bash shell. The dot command is a dot symbol (from the Bourne shell) which is another name of the source. Similarly, the variables configured in the current script will also be used as the script environment, the source (or point) commandIt is usually used to re-execute the modified initialization document.Such as. bash_profile and. profile.
