For most people, the Mac's OS X is all about the graphical user interface. But system administrators and power users know that the Mac's command-line interface can be a powerful time saver and, in many cases, the only method to accomplish certain tasks. The command shell itself, delivered by Apple's included lTerminal program, is a wonder of open source. Bash - for 'Bourne again shell' - was developed by free-software guru. It's widely used on operating systems of all kinds, including iOS, Linux, Unix, and mainframes. There's already a huge brain trust of tool knowledge around using Bash as a systems administrator's command shell. But OS X brings its unique capabilities to the command-line table, in the form of utilities that leverage OS X's user interface, file system, and security capabilities.
I've scoured the Internet for the best of the best of these utilities. Some you may already know, but others are sure to make you sit up and exclaim, 'Sweet!'

All commands, unless otherwise noted, run on all versions of OS X since 10.4 Tiger. For most of these commands, you can get more documentation using the 'manpage' system: Type man followed by the command name. For example, man lsof displays the manual page for the List Open Files command.

I thought I had posted this question here already but don't see it. If this is a repost, or if the answer is already given in another thread, please accept my apology. I'm a relative newbie at Unix. I purchased a G4 dual processor 450 and had OS X Jaguar 10.2.8 before upgrading to OS X Tiger 10.4.3. I'm using OS X primarily to use BRL-CAD, and am having lots of learning opportunities getting it going on the Mac, chief among these it seems is that help is offered which usually refers to edits to files used by bash. Since my shell is tcsh, which I'm told was the default shell in Panther and prior versions of OS X, I am considering switching shells to bash.
My question is: should I switch to bash, and if I choose to do so, how much grief will that cause? Thanks, David. Ok, you asked! Best shell is zsh.
And since it is the best, there is no need to tell why. There are lots of superior features in zsh, but I like its -. expansion.
It is like a quick find command built into the shell for example: ls./.txt shows all.txt file in current directory, its subdirectories etc. vared; lets you edit environment variables inside the shell. For example today, I had to edit Java's CLASSPATH. As you might know, CLASSPATH has a habit of getting big. With vared, editing it is easy - editting multiline commands. I use for i in.ext quite alot.
With zsh's multiline editing, it is easy And I did not even mention zsh's main features, like parameter expansion: zsh knows that for command javac, you give parameter that ends with.java, so typing javac and pressing zsh expands only.java filenames. Choose Preferences from the Terminal menu. Select the option 'Execute this command (specify complete path):' Change the selected text entry from /bin/tcsh to reflect a different Terminal shell, such as: /bin/bash /bin/csh /bin/zsh /bin/zsh-4.0.4 (Mac OS X 10.2.8 or earlier) /bin/zsh-4.1.1 (Mac OS X 10.3 or later) /bin/ksh (Mac OS X 10.4 or later) Close the Terminal Preferences window. Quit and open Terminal again. The first and subsequent new Terminal windows open with the shell that you designated in Preferences. When I launch terminal I get: -bash: setenv: command not found G4: root# How can this be corrected?
