How can you tell what a terminal command will act on?
Check which shell is running and which folder it is using. Start with a command that only reports that folder, then match the result to the project you meant to work on.
What is the difference between a terminal and a shell?
The terminal is the window where you type and see results. A shell such as PowerShell or Bash interprets the text. Two tabs in the same app can use different shells or start in different folders.
What is a useful first check in a local terminal?
Check which shell is running and which folder it is using. In a known local PowerShell tab, Get-Location reports the current folder. In a known local Bash tab, pwd reports it. Neither example edits files.
A folder path is the address of a folder on that computer. Compare it to the address you expect before continuing. If you cannot confirm the shell or whether the session is local, draw the expected result on paper.

|---|---|---|---|---|
| Windows Terminal | Terminal window for Windows. Profiles can open installed shells such as PowerShell. | Choose a known local profile and check the folder with the command for that shell. | Keep the profile settings you need. Install the shell and copy your files separately. | Open-source app. Check the Windows install options and shell requirements. |
| iTerm2 | Terminal window for macOS with tabs, panes and profiles. | Check which profile and pane are active. In a local Bash session, pwd prints the folder. | Back up the relevant preferences. Keep shell settings and project files separately. | Open-source Mac app. Check the download’s macOS requirements. |
| Bash | Shell that reads commands inside a terminal window or from a script. | In a known local Bash session, pwd reports the current folder. | Keep scripts, their Bash version and the programs they call. | GNU free software. Check the project’s required Bash version and platform setup. |
| Zsh | Shell that interprets commands and can suggest completions. | In a known local Zsh session, use pwd to check the folder. | Keep the relevant startup settings and a list of the tools they use. | Freely available. Check your installed Zsh version and the project’s shell requirements. |
| PowerShell | Shell and scripting language for running commands. | In a known local tab, read the version and use Get-Location. | Keep scripts, required modules and the relevant host profile settings. | PowerShell 7 is open source and runs on supported Windows, macOS and Linux systems. |
| Warp | Terminal window that groups each command with its output. | Confirm the local tab and shell, then use that shell’s folder check. | Keep Warp preferences, shell settings and project files separately. | macOS, Windows and Linux. First launch needs internet. Login is optional. |
| Ghostty | Desktop terminal that opens an installed shell. | Check the new local tab’s actual folder. Inheritance depends on the setup. | Keep the terminal preferences, shell settings and project files separately. | Open-source macOS and Linux app. Current Mac download requires macOS 13 or later. |
| fish | Shell with interactive suggestions and completion. | Check the folder with pwd before accepting a suggestion from history. | Keep relevant startup settings, custom functions and a note of persistent preferences. | Open source. Check the install options for your operating system or Windows environment. |
| tmux | Terminal session manager that puts multiple programs in one view. | Check the machine, session, active pane and its folder. | Keep the configuration and project files. A running session belongs to its original computer. | Open source. Install it on the Unix-like system that will run the session. |
| Starship | Prompt that shows context such as the folder and Git branch. | Read the prompt, then verify the full folder with your shell’s command. | Keep the prompt config, shell initialization and font choice separately. | Open source. Check shell setup and the font for the default symbols. |
What moves when you switch terminal apps or computers?
Keep a short record of the shell and version a project expects, the folder where a task starts and any programs it needs. Terminal profiles can store preferences, but the project and those programs are separate.
How can you rehearse the check without opening a terminal?
Draw two local tabs on paper. Give each a shell name and a different fictional folder. Use no remote connection or live project.
- Pick a tabMatch the shell name to the instructions you have.
- Write the path you expectIf you expect sample-site and see sample-notes instead, stop and check the current folder.
