Linux how to create an alias for a command
To create a temporary alias, you only need to run the alias command in the current session, such as aliasll='ls-la', which will be invalid after closing the terminal; 2. To permanently save the alias, you need to add the alias command to the ~/.bashrc (Bash) or ~/.zshrc (Zsh) file, and run the source command after saving to make the changes take effect immediately; 3. You can use the unalias command to delete the temporary alias, or redefine it to overwrite the existing alias. It is recommended to use meaningful names and avoid overwriting standard commands to maintain the predictability and manageability of the system.
