It is the default shell on Linux and Mac OS X, and has even made the jump to Windows via Cygwin. In summary: login shells read files like *profile*, non-login shells read ~/.bashrc, and you should fix Terminal.app.īash is a shell originally written by Brian Fox at the Free Software Foundation in 1988. It is 99 for 1 year of updates or 139 for 3 years of updates. It would be nice to have MobaXterm on Mac, but sadly its only for Windows.

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. Although the Mac version isnt as fancy as the Windows version, it is full featured for everything Ive ever needed in a multiple terminal emulator. In the terminal emulator packaged with OS X (Terminal.app), new windows are by default opened with login shells. Unfortunately, this customary behavior isn't adhered to by Mac OS X.

This makes non-login shell customizations available to login shells. But if you want to share declarations and/or aliases across all interactive shells (login or not), you should put this in your. It is assumed that by running the emulator program, you have already logged in. On Linux, it is customary for terminal emulators not to declare their interactive shell processes as login shells. This is why you should keep any output-producing commands in the files read by login shells (. bashrc and will fail spectacularly if any part of. bashrc, but scp and rcp aren't as well-behaved. Well-behaved scripts or programs that use Bash don't attempt to load. This is essential because, when running autonomously, a shell's standard streams might be redirected, and aliases or environment variables could confound running scripts.

Non-login shells read ~/.bashrc, and non-interactive shells try not to read any files.

When login shells exit, they read ~/.bash_logout. 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. Bash processes spawned from login or started with the '-' or '-login' flags believe they are login shells. The second condition is whether your shell is declared as a login shell. This condition holds true most of the time the exception is when you run Bash with the '-c' flag: $ bash -c /usr/bin/something A session runs interactively when the standard streams are actually connected to a terminal. The first is whether your shell is running interactively. 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.
