Terminal Snippets¶
Terminal usage snippets for macOS. This is a collection of snippets that I use without specific category.
Install macOS Updates via CLI¶
softwareupdate -i -a
Install Command Line Tools¶
xcode-select --install
Shell Safe rm¶
Source shell-safe-rm github
A much safer replacement of shell rm with ALMOST FULL features of the origin rm command.
Initially developed on Mac OS X, then tested on Linux.
Using safe-rm, the files or directories you choose to remove will move to $HOME/.Trash instead of simply deleting them. You could put them back whenever you want manually.
If a file or directory with the same name already exists in the Trash, the name of newly-deleted items will be ended with the current date and time.
Install with npm:
npm i -g safe-rm
Add Alias to your zshrc config
alias rm='safe-rm'
Disable StrictHostKeyChecking in SSH¶
To disable strict host checking on OS X for the current user, create or edit ~/.ssh/ssh_config and add the following lines:
StrictHostKeyChecking no
Set macOS Hostname via CLI¶
sudo scutil --set HostName <NewHostNameHere>
Syntax Highlighting for Nano¶
