Run App From Unix Mac Terminal

Opening Applications using the Terminal. Most applications in OS X are opened by using a graphical approach like mouse click actions or services like Spotlight; however, you can also open applications using the OS X Terminal. This might seem unnecessary, but it can have its uses. For instance, I have a Mac Mini running the third-party media. Apple's Terminal provides you with a UNIX command line inside the OS X environment. You can enter the open command here to open any application, or to open a file with the application of your choice. There are several ways to adjust this command to suit your purposes, including the ability to host the application in your Terminal window. W, -wait-apps Blocks until the used applications are closed (even if they were already running).args All remaining arguments are passed in argv to the application's main function instead of opened.n, -new Open a new instance of the application even if one is already running.j, -hide Launches the app hidden.

If you’re working in Terminal on your Mac, you need to know the most important UNIX commands: those that work with directories, those that work with files, and miscellaneous but commonly used commands.

If you would like to run the app as a different user (e.g., the root account), then you can first switch user accounts in the Terminal with the “su” command, or use “sudo” before specifying the path to the Mac OS application, and this will launch the program as root (note that this might not always work). Cocoa Applications To run applications as root, we use sudo. However combining open and sudo in this form: sudo open /path/to/some.app results in sudo running open as root, but open still opens the application as the original user!!!

Folders are called directories in UNIX. Commands that refer to filenames, as most do, assume that you’re talking about files in the working directory. When you open the Terminal window, the working directory is set to your home directory, abbreviated ~. Bash shows you the current working directory and your username to the left of its prompt. The following table lists common directory-related commands.

UNIX Directory Commands
CommandWhat It Does
lsLists the names of the files in the working directory. For more
complete information, use ls –alF (.
cd directorynameChanges the working directory to the one you named.
cd .Brings you up one directory level.
cdReturns you to your home directory.
pwdDisplays the pathname of the current directory.
mkdir newdirectorynameMakes a new directory.
rmdir directorynameRemoves (deletes) an empty directory.

As in Windows, you can redirect the output of a command to a text file. So if you want a record of the files in a folder, type cd, followed by a space, drag the folder’s icon to the Terminal window, and press Return. Type ls > mydirectorylist.txt and press Return again. A file named mydirectorylist.txt will appear in the folder you chose. You can open the file in TextEdit to see a list of the files in that directory.

This table lists commands commonly used when working with files in the Terminal window.

Working with Files
CommandWhat It Does
cp filename1 filename2Copies a file.
chmodChanges permissions for access to a file. Study the man page
before using this one.
diffCompares two files line by line (assumes text).
more filenameDisplays a text file one page at a time. Press the spacebar to
see the next page; press Q to quit. The man command works through
more.
mv filename1 filename2Moves a file or changes its name.
rm filenameRemoves (deletes) a file.

This last table explains other handy commands that anyone getting started in Terminal will likely want to know.

Miscellaneous Commands
CommandWhat It Does
Control+CTerminates most operations.
dateDisplays the current date and time.
echoRepeats whatever appears after the command (after
expansion).
helpDisplays a partial list of bash commands.
historyDisplays the last commands you typed. You can redo a command by
typing an exclamation point (!) followed immediately (no space) by
the number of that command in the history list. To repeat the last
command, type !!. To repeat the last filename, type
!*.
picoA simple UNIX text editor.
psDisplays a list of running processes.
sudoLets you carry out commands for which the account you are using
lacks authority. You will be asked for an administrator’s
password.

When you’re working in Terminal, you don’t have a Trash Can to which deleted files are moved pending ultimate disposal. Delete it, and it’s gone. In general, UNIX has no Undo function.
