I spent some time today installing Ruby, Rails and other web development stuff through homebrew and rvm. But somewhere i must have put the wrong command in the terminal since my terminal on OS X Lion (same with both standard terminal and iTerm2) now looks weird.
How do I get rid of that red tilde and black arrow and get it back how it looks as default?
As I am a beginner at terminal commands I would appreciate your help.
it seems like PS1 has been changed.
what you can do now is to change it back, or simply delete it to return to default.
in terminal, do the following:
cd ~
grep "export PS1" .*
then you will see some outputs, it might be in .profile or .bashrc, (just ignore the history one)
you can use whatever to open the file. or just open .filename in terminal, delete the line with export PS1, save, relogin. the problem shall be resolved.

I have been spending some time looking for the solution. I have reinstalled Vim on my mac for several times using MacPorts. The vim --version command show that +clipboard and +xterm_clipboard, so I should be good to go. However, when I type "+yy or "*yy inside vim, the :reg command show that the register changed to the current line, but when I do paste outside vim, the content still did not change. Everything in vim I can tolerate to trade off its super flexibility, however, this copy/paste which is frequently used but extremely difficult in vim really driving me crazy...
I've found that if I add set clipboard=unnamed to my .vimrc, then pasting outside of vim will paste the contents of the * register. For + you might try set clipboard=unnamedplus.
Problem solved. I am always using system vim, which is /opt/local/bin/vim. I think there was some glitch going on there. So I installed MacVim, and link vim to MacVim by adding the following code to my bash profile (~/.bash_profile)
alias vim='/Applications/MacVim.app/Contents/MacOS/Vim'
Registers work perfectly with MacVim. Even though vim --version reveals that it is +clipboard but -xterm_clipboard.
For me, it was a matter of updating the vim that ships with OS X (7.3) via homebrew to 7.4.
I have used vim to make small scripts in python and typesetting things in LaTeX. So it is very useful to run applications from vim by typing :!python or :!pdflatex etcetera. But after upgrading to el capitan, this seems not to work anymore, get message like /bin/bash: pdflatex: command not found. But the funny thing is that it is possible to run the applications directly from terminal. Anyone that know how to set the correct that for vim as well?
$PATH variable not properly set in gvim/MacVim when it is opened from the finder
first check :!echo $SHELL and see if SHELL is set to bash or not
then try to set your path in your ~/.bash_profile?
export PATH=<dir_contains_pdflatex>:$PATH
I can't seem to change the default bash editor in OSX Lion terminal.
I've tried setting:
export EDITOR='<editor symlink with parameter>'
in both ~/.bashrc & ~/.bash_profile . The symlink is subl, and the parameter is -w.
from the prompt it is:
subl -w
I have restarted terminal after each but every time I enter:
edit test-file.md
it opens TextWrangler (not the editor I've set). I've tried opening the symlink from the command line with no problem. I realize that I should probably just get used to typing the symlink, but the anal side of me wants to know why I can't set the default editor.
Any help with this trivial problem would be appreciated, thanks in advance!
I'm not even sure what edit command is. i don't have in on my Mac OS X Lion. Whatever it is, sounds like it ignores the EDITOR env variable and uses your MacOS X application settings.
What you want can be accomplished with the alias shell command though:
alias edit=/path/to/vim
I'm using Terminal.app on Mac 10.6.6 and want to upgrade vim. Should I install it in /usr/local?
I'm asking because my native vim install is messed up for some reason. Sometimes, when I open it and move up and down, the whole line changes to another line on the screen, like dancing chairs. But if I type :q it quits fine because nothing actually gets changed (cause I'm just moving the cursor around), but I can't see what I'm doing because when I move to a new line, that line gets replaced with another line about 6 lines below, but it's random.
$TERM = xterm-color
I installed Mercurial & ack via CPAN (for which I installed File:Next) yesterday, so maybe that did it. I have MacVim, but I want vim to work too cause I use it for Git, etc.
Try running vim -u "NONE" to load your Vim without your .vimrc, this might be the culprit in this case. If everything works like it should you can try re-enabling things one by one so you can see what caused it.
If you want to update your Vim I can recommend homebrew which has a so called formula with a regularly updated Vim.
Put the mvim script that came with MacVim in your $PATH and use it on the terminal with the -v option or a symbolic link named vim.
Also, use TERM=dtterm for Terminal.app. Programs will behave better.
I don't know what has happened, but in my Terminal on Mac OSX 10.5 it can no longer find my sudo command, or find command, etc. They are there because if I put /usr/bin/sudo or /usr/bin/find it works fine...
My .bash_login file looks like this:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin$PATH"
My .bash_profile file looks like this:
export PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:/Library/Python/2.5/site-packages/django_trunk/django/bin:/usr/local/mysql/bin:/usr/bin/sudo$PATH"
I'll say now, I don't really know what I'm doing with the Terminal. I'm just a beginner to it all, and I must of done something for the environment variables (is that what they're called?) to be lost. I presumed I'd just have to make sure the /usr/bin/ path is in my bash files, but they are, and it doesn't seem to work. Please help!
Also, when I do use the /usr/bin/find command, it says "Permission denied" to me, even though I am logged into Mac OSX as the System Administrator account. I don't understand.
Any help would be grand. Thank you - James
It looks like both of your PATH exports are malformed:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin$PATH"
The end bit there won't work. It should be:
export PATH=/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin:$PATH
Notice the colon before '$PATH'? It's important ;)
Also, the double quotes are not necessary.
If this doesn't work, we will need more information. It is possible that something else is modifying your path even after your shell configurations are loaded.
Can you post the results of:
$ echo $PATH
Configuration files are not always a good indication of the current environment variables, since they are modified by many programs and files, all across your system. To see all of your environment variables, you can run:
$ env
This should fix the problem completely and permanently.
first, export environment paths by using below command in the terminal.
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
now you have the commands you want. (eg. try ls. You'll see the command is working). But this is only for the current session. If you close the terminal and open a new one, you will have the previous issue. To make this change permanent, use below command,
go to home directory
cd ~
open .bash_profile file in nano / vim (I'm using nano here)
nano .bash_profile
This will open up nano editor. In a new line, paste the following;
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:$PATH
press 'control'+'o' to save (WriteOut) and 'control'+'x' to exit nano.
All done ! Now try the commands.

I went trough the same issue and here is how I solved it.
First of all I reverted the file to its original doing this way
/usr/bin/nano ~/.bash_profile
In my case I was not able to make work any command alias. Even vi or vim didnt work without specifying the full path of that command.
If nano is not installed just replace nano in the command by the editor installed
After that just restart the computer. In my case as I said bellow I could not use any command. When trying to do /usr/bin/source ~/.bash_profile
that command failed. So I had to restart the OS and it worked
