How to install Linux on a Mac: Replacing OS X/macOS with Linux. Running Linux inside a virtual environment is all well and good, but if you're a more seasoned Linux user you may want to replace OS. Mac OS X Leopard: 4.4BSD/Mach3.0 (iX86) Apple Darwin 9.6.0 (i386) Apple Mac OS X 10.5.6 (iX86) Ubuntu Jaunty server: LSB (iX86) GNU/Linux 2.9/2.6 (i686) Ubuntu 9.04 (iX86) Debian Lenny: LSB (iX86) GNU/Linux 2.7/2.6 (i686) Debian GNU/Linux 5.0 (iX86) This produces pretty satisfactory results, as you can see.

By default, your system does not have the .bash_profile file for your user. Therefore you will need to create it to set environment variables for your current user when starting new session.

In this tutorial, we are going to create a .bash_profile to set $JAVA_HOME environment variable.

  • First, we are going to check out that .bash_profile does not exist.
  • Go to user home and create the .bash_profile file.
  • Push i key to insert contents with VIM editor, and write the environment variable.
  • Push esc key and type :wq to save and close the file. Then, reload the .bash_profile file.
  • The .bash_profile has been executed, and $JAVA_HOME has been set.

When it comes to setting up your command line environment in Bash, there are two conditions by which Bash decides which files to read at startup.

The first is whether your shell is running interactively. A session runs interactively when the standard streams are actually connected to a terminal. This condition holds true most of the time; the exception is when you run Bash with the '-c' flag:

The second condition is whether your shell is declared as a login shell. Bash processes spawned from login or started with the '-' or '--login' flags believe they are login shells.

Here's the standard behavior: login shells always look for the bash configuration files with 'profile' in the name, in this order: /etc/profile, ~/.bash_profile, then ~/.bash_login and lastly ~/.profile. When login shells exit, they read ~/.bash_logout.

Non-login shells read ~/.bashrc, and non-interactive shells try not to read any files. This is essential because, when running autonomously, a shell's standard streams might be redirected, and aliases or environment variables could confound running scripts.

Well-behaved scripts or programs that use Bash don't attempt to load .bashrc, but scp and rcp aren't as well-behaved. They source .bashrc and will fail spectacularly if any part of .bashrc prints to the standard out. This is why you should keep any output-producing commands in the files read by login shells (.bash_profile and the like).

On Linux, it is customary for terminal emulators not to declare their interactive shell processes as login shells. It is assumed that by running the emulator program, you have already logged in. But if you want to share declarations and/or aliases across all interactive shells (login or not), you should put this in your .bash_profile:

This makes non-login shell customizations available to login shells.

Unfortunately, this customary behavior isn't adhered to by Mac OS X. In the terminal emulator packaged with OS X (Terminal.app), new windows are by default opened with login shells. This can be remedied by accessing the Preferences window and, under Startup, specifying that shells should open with /bin/bash and not a login shell.

Bash For Mac Os

In summary: login shells read files like *profile*, non-login shells read ~/.bashrc, and you should fix Terminal.app.

For Bash Mac Os X

Bash is a shell originally written by Brian Fox at the Free Software Foundation in 1988. It is the default shell on Linux and Mac OS X, and has even made the jump to Windows via Cygwin.
