The dockspace alias uses this hack to add a spacer item to the dock. The substitution can be long and multiple commands can be separated by alias dockspace="defaults write persistent-apps -array-add '' killall Dock " This is useful to get notified of long running commands: $ hdiutil convert image.sparseimage -format UDZO image.dmg badge The first command will play a system alert and set a ‘badge’ on the terminal application if it is in the background. You can also use aliases to make complex or hard to memorize commands easier to remember: alias badge="tput bel" Since the output of the alias is not checked for further alias substitutions you cannot use alias cd.=. Since alias substitution only takes place at the beginning of the command, you can still use. You can add short cuts to cd to parent folders: alias. You can still use \rm to bypass the alias, if you believe you know what you are doing and want to avoid being prompted several times. Then if you do something that could destroy an existing file you will be prompted to confirm: $ rm my_important_file Some users like to alias the potentially dangerous commands rm, mv and cp with the -i option, which forces the user to confirm when a file is going to be deleted or overwritten: alias rm="rm -i" If you are unsure if a command has an alias or want to know what gets substituted, then you can have the alias definition printed with $ alias lsĪlias lll='ls can also list all defined aliases by running alias without any arguments: $ alias Since alias substitution only happens at the beginning of the command, you can also bypass it once by starting the command line with a different character: $ "ls" -SĮither way of typing this will use the original ls command, avoiding substitution, just this once. This will return to the default ls command (for this bash instance only). You can unset or delete an alias with the unalias command: $ unalias ls Note the lack of spaces around the ‘ =’, as usual when assigning values in bash. Then, when ever you type ls it will be replaced with ls -l. You can make the alias more complex if you want: alias lll="ls you always want to use the long format of ls, you can alias the ls command itself: alias ls="ls -l" Since subsequent arguments are left alone they will just be picked up by the substituted ls command, so if you type ll -a bash will substitute that to ls -l -a and it will work just your would expect. Once you have set the alias, anytime you type ll at the start of a command, bash will replace it with ls -l before executing. bashrc it will not automatically be loaded into any shell that is already open, you either have to close the Terminal window and open a new one or write $ source ~/.bash_profile If you want an alias to exist in all your shells (and usually you do), you need to add the above line to your. When you open a new terminal window it will know nothing of this alias. You can type this alias definition directly into bash but then the definition will only exist for that particular shell. For example a common alias is to define: alias ll="ls -l" The closest shell equivalent for Finder alias files are symbolic links.īash aliases are basically text substitutions. Note: bash aliases are something completely different from Finder aliases. This post will look at some useful aliases and functions.
There are (mainly) three customizations you can perform: This is obviously not the same as changing the actual user name, but for just creating an abbreviation or for a minor adjustment for aesthetic reasons (changing text case, etc), this will work.In the previous posts we talked about which files you could use to customize your bash environment.

You will now be able to login from the various Mac OS X lock screens including standard logins, user account switching, or screen savers, with the shortened user name alias.
You can enter multiple aliases, and they can be longer or shorter than what the actual account name is. Click on the “+” sign at the lower portion of the Advanced Options panel to add a new user name alias to the account.
