When working in a terminal, it's common to repeat the same commands over and over again. This can be time-consuming and tedious. Luckily, most terminals keep a record of the commands you've typed in the past, so you can quickly access them without having to retype them. In this blog post, we'll look at how to access command history in Ubuntu, Windows, and macOS.
Ubuntu
In Ubuntu, you can access your command history by using the history command. Simply type history in the terminal, and it will display a list of all the commands you've entered. Each command is numbered, and you can run a command by typing its number and pressing Enter. For example, if you want to run the command at line number 10, type !10 and press Enter.
To search through the command history, use the Ctrl+R command. Press Ctrl+R in the terminal, and start typing the command you want to search for. The terminal will display the most recent command that matches the characters you typed. If the command is not the one you want, keep pressing Ctrl+R to cycle through the matches.
Windows
In Windows, you can access your command history by using the doskey /history
command. This will display a list of all the commands you've entered in the current session. To run a command from your history, type doskey followed by the command number. For example, if you want to run the command at line number 5, type doskey 5 and press Enter.
To search through the command history in Windows, use the F7 key. Press F7 in the terminal, and a window will pop up with a list of all the commands you've entered in the current session. You can use the arrow keys to navigate the list, and press Enter to run the selected command.
macOS
In macOS, you can access your command history by using the history command, just like in Ubuntu. Simply type history in the terminal, and it will display a list of all the commands you've entered. Each command is numbered, and you can run a command by typing its number and pressing Enter. For example, if you want to run the command at line number 15, type !15 and press Enter.
To search through the command history in macOS, use the Ctrl+R command, just like in Ubuntu. Press Ctrl+R in the terminal, and start typing the command you want to search for. The terminal will display the most recent command that matches the characters you typed. If the command is not the one you want, keep pressing Ctrl+R to cycle through the matches.
Conclusion
Accessing command history in Ubuntu, Windows, and macOS can save you time and make your work in the terminal more efficient. By using the history command and keyboard shortcuts like Ctrl+R and F7, you can quickly access and reuse the commands you've entered in the past. Try using these commands the next time you're working in a terminal and see how they can streamline your workflow.
