How to modify terminal prompt on Linux (specifically Ubuntu), so that prompt is in new row after username#host-path?
Like on the picture below (git bash terminal on win7):
Here is detailed page that should help you

And to directly answer your question:
In your .bashrc file, located in your home directory, find any entry that ends with \$ and add a newline to it so that it would end with \n\$.

I'm trying to run code on Linux environment
Here's the code (saved as hello.pl):
#!/usr/bin/perl
use strict;
use warnings;
print "Hello You\n";
Here's what I tried on my linux environment:
%perl hello.pl
I tried listing out the path starting from C:\Users\... and so on
I keep getting error that says:
Can't open perl script "hello.pl": No such file or directory
You have to be located in the same folder with the hello.pl in the "window" (aka terminal, or console) that you try to execute perl hello.pl.
On linux, you can determine the folder that you're in by issuing pwd.
If you're not in the same folder (the most probable cause of your error), you have 2 options:
Navigate to that folder with cd /path/to/your/script/location you have to replace the /path/to/your/script/location in the example, with your actual path
Execute the file with perl /path/to/hello.pl - of course, you have to replace the /path/to/ in the example, with your ac
Also, you can try and view the file from the console running a less hello.pl
In cygwin you might try: /cygdrive/c/Users/bonan/Desktop/perl/hello.pl.
Alternatively at your prompt try tying in just perl without hitting enter, and then drag the hello.pl file from its file explorer location into the terminal window. That should paste the full file path to the file as text into the command prompt. If you're using cygwin I forget it if properly pastes the path with forward-slashes, like /cygdrive/c/Users/bonan/Desktop/perl/hello.pl, or if it pastes what it would in cmd with backslashes as you've indicated you typed yourself.
The other thing to do that's relatively easy is right click the file and choose to open a terminal or shell here, which for cygwin you can get in your context menu by running chere -i once (it actually says "Bash prompt here" I think). And there's similar context menu options for cmd, powershell, an actual linux bash, or mac os x's terminal ... once you're in the same path as the file, you can just type perl heltab and autocomplete the filename assuming no other files in the same folder start with "hel".
Hi I add a new user in my linux mint. But after login that user, some feature losted in the terminal. Such as I cannot use up-arrow and down-arrow in the keyborad to show the previous command. Also there is no color in for different file. Someone could tell me the way to configure these setting? or some link. Thanks
The bash history is user-dependent. You can change the bash settings in the .bashrc file in your home directory, or you can tweak the file /etc/bash.bashrc.
I know little about Vim in terminal(Mac) and the other day I was working copy and pasting text and i think I accidently did it when in terminal. Now whenever I open terminal it instantly loads on Vim Ex mode. I know how to quit Ex mode once in terminal but is there any way i can get rid of Vim loading when I open Terminal?
Thanks
Edit: To explain further to what i mean when I open terminal.app from Utilities I get the following
and the only way I get back to the command prompt is by typing quit every time I open terminal and i cant understand why the Vim process is running in the first place.
I was just outside the terminal in a document copy and pasting text then accidentally did a command v to paste within terminal which resulted in this happening.
It appears that you've accidentally updated one of your shell startup scripts so it launches vim.
If your default shell is csh or tcsh, take a look at .cshrc, .tcshrc, and .login in your home directory, and look for a command like vi -e or vim -e.
If your default shell is bash, check .bashrc and .bash_profile.
It may be easier to figure out which file you messed up by checking which file in your home directory was modified most recently:
% ls -altr $HOME | tail
-a lists all files, including files whose names start with ..
-l gives you a long listing, showing timestamps.
-t sorts by modification time.
-r reverses the order, so newer files are shown last
I am new to linux.
I am trying to set up arcanist.
I am done with git clone and adding the path in environment variable, however I am confused on how to set up the tab completion for arcanist commands.
In the arcanist user guide it says that you need to add source /path/to/arcanist/resources/shell/bash-completion to your .bashrc, .profile files.
What are these files and how can I edit them to work with arcanist with the tab completion.
The .bashrc, found in your home directory, is the configuration file for that user for bash.
There is a global bashrc usually located in /etc/bashrc.
The difference to .profile is that the .bashrc is executed every time you start a terminal (bash) while .profile only once when you use a login shell.
The command source loads everything that is inside the file you use with that command and treats it as if you wrote those commands in the .bashrc yourself. I guess in /path/to/arcanist/resources/shell/bash-completion are aliases/functions/etc. which enable tab-completion with arcanist.
Edit: for bash, the profile file is usually called .bash_profile.
After lot of googling and asking people, I finally did it.
First of all I had to export the path where my arcanist code from the github has been cloned in the ~/.bashsrc file(in bold below)
export PATH="$PATH:$HOME/.rvm/bin:$HOME/arcanist/bin/"
After this command, I copied the function which was present in the /arcanist/resources/shell/bash-completion into the bashrc file
And then I closed and open the terminal and bingo I was able to get arc and it's command as auto completion on striking tab.
Thanks ap0 for the comments.
I was going over this article and it states in step 3
Add the following to your .bashrc (or the appropriate startup file for your shell) To use it immediately, be sure to type “source .bashrc”
Any idea on how I could know what my startup file is ? I am using putty ?
Once you use putty to SSH into your server, you can run "ls -al .bashrc" and it should show you the file, edit this with an editor you know, if none, then use vi like this "vi .bashrc".
Go to where you need to edit the file and type in "i" to put vi in Insert mode. Next type in your text. Once you are done press the escape button and ":wq", no quotes for the i or :wq.
Next you can source it by typing "source .bashrc" and the setting you added should be part of your BASH shell environment now.
The .bashrc is a file which is called by bash before on each start of a new interactive shell. The file can be used to setup the environment, export variables, create aliases and functions and more...
There are usually multiple instances of that file. One per system and one per user to allow system wide configuration but also customization by users ( users bashrc will be sourced after the system wide bashrc and can overwrite things). I suggest to add the lines to your user's bashrc first. The file is located in your home folder. Type:
vi $HOME/.bashrc
in order to edit the file. If you aren't familiar with the vi editor you can choose an editor of your choice like nano, mcedit or even a GUI text editor, but mind that a GUI editor's file dialog may hide the file because it's name starts with a .
Once you managed to edit the file, start a new connection or simply type
source $HOME/.bashrc
in order to parse the file
A path which will work with any bash shell regardless of operating system (macOS/Linux/BSD etc.) is:
~/.bashrc
check your home directory ...because it exists in user's home directory.
check /home/username/ on your terminal if you are using RHEL or CentOS.
.bashrc and .bash_profile are bash config files (bash shell script) that bash runs(execute) whenever it is started interactively. It initializes an interactive (non-login) shell session and the config is read from these files $HOME/.bashrc
.bashrc is a standard hidden file located in your home directory.It determines the behaviour of interactive shells.
.bashrc runs on every interactive shell launch.If you say: $bash
For login shells, the config is read from these files:
/etc/profile (always sourced)
$HOME/.bash_profile (the rest of these files are checked in order until one is found,then no other are read)
$HOME/.bash_login
$HOME/.profile
For example: I added an echo to my .bashrc and .bash_profile files and whenever I called bash or bash -l command in terminal it showed me the echo.
