You can access the file by simply typing: nano ~/.bashrc bashrc file (this is a configuration file that loads up every time you load up a session). So, to make this a permanent change, you need to add it to. If you close the session, you will lose the customization. The above command that I mentioned temporarily customizes the bash prompt for the current session. So, just keep in mind the codes for customization and play around with it till you’re sure you want this as a permanent change. This is how your bash prompt will look like after typing the command:Īs you can notice, the color customization is the same no matter the order. You just need to type in the following to change the color and font: PS1="\e\h:\w\a\$]" Color range for background colors: 40-47.Codes for text format: 0 for normal text, 1 for bold, 3 for italic and 4 for underline text.The output in your case can be different, but the variables will be the same, so you need to play with the commands mentioned below depending on your output. \u indicates the username followed by the symbol.\e is a special character that denotes the start of a color sequence.We need to focus on the first part of the output: \0 \ \h: \w\a\]$ You can learn more about it in the man page.įor instance, when you type in: echo $PS1 You will need to utilize the PS1 environment variable which controls what is being displayed as the prompt. However, you can tweak the font and color of the bash prompt ( :~$) using commands. Tip 5: NOT RECOMMENDED: Changing the font and color of the bash prompt (for advanced users) Similarly, you can also change your username, but it requires some additional configuration that includes killing all the current processes associated with the active username, so we’ll avoid it to change the look/feel of the terminal. To permanently change the hostname, you need to type in: sudo hostnamectl set-hostname CUSTOM_NAME So, when you restart, it will revert to the default. However, this will be applicable only for the current sessions.

This recipe should work with at least Python 2.1+.To change the hostname, you can type in: hostname CUSTOM_NAME (In a real-life use case, you'd want to check if ProgressBar raised an exception, and if so, fall back on a simpler progress bar implementation.) progress.update(float(i)/len(filenames), 'working on %s' % filename) > for i, filename in zip(range(len(filenames)), filenames): > progress = ProgressBar(term, 'Processing some files') (caveat: if you need to print other output while using the progress bar, then clear it before you do otherwise, it may overwrite whatever you printed).

Call clear() to erase it when you're done.

To use it, first construct a ProgressBar instance, and then call the update() method whenever you wish to update its progress. The second half of this recipe is really just an example use case, showing how TerminalController could be used to generate a fancy progress bar. Since this recipe uses terminfo, this recipe should support more terminal types than simply checking if $TERM=vt100 and using vt100 control sequences, or other similar approaches that are often taken. If the terminal does not support color, then the same output string will be generated, just without the color. These can be simply included in normal output to the terminal: > term = TerminalController() > print 'This is '+term.GREEN+'green'+term.NORMAL Alternatively, the `render()` method can used, which replaces '$'), 'paper is ripped' `TerminalController` defines a set of instance variables whose values are initialized to the control sequence necessary to perform a given action. Import sys, re class TerminalController : """ A class that can be used to portably generate formatted output to a terminal.
