Methods to Identify What Shell You Are Using
Here’s a detailed approach to discovering what shell you are using:
1. Check the Default Shell Variable

- Open your terminal application.
- Use the command that displays the content of the SHELL variable.
The output will indicate the shell in use, such as /bin/bash for Bash or /bin/zsh for Zsh.
2. Examine the Current Shell Process
You can also identify your shell using the currently running shell process. This method is helpful if Determine What shell you are using other than your default one in your current terminal session.
- Open your terminal.
- Check the list of processes to find the one corresponding to your shell.
The process list will include the command name of the shell you are currently using. For instance, if you see Fish, you use a Fish shell.
3. Review Your User Account Settings
You can review your user account settings to find out which shell is set as your default login shell. This often involves querying user account details.
- Use system commands to view user account settings.
- Look for the shell field in the output, displaying the path to your default shell.
For example, the output might show /bin/zsh, indicating that Zsh is your default shell.
4. Look at Shell-Specific Configuration Files
Different shells have their configuration files. Examining these files allows you to determine which shell you use based on their presence and content.
- Bash: Look for configuration files like .bashrc, .bash_profile, or .profile in your home directory.
- Zsh: Check for files like .zshrc or .zprofile.
- Fish: Look for the configuration file in .config/fish/config. Fish.
- Tcsh: Check for files like .tcshrc or .cshrc.
The presence and content of these files can give clues about which shell you are using.
Common Issues and Troubleshooting

If the SHELL variable does not display any output, it could be due to an unset environment variable. In this case, check your shell’s initialization files to ensure they are correctly set up.
Different Shell in Different Sessions:
If you use a different shell in various Terminal sessions, confirm your default shell by checking the user account settings or examining the running processes to ensure consistency.
