I'm not sure exactly what I did besides try to uninstall an application but it seems my prompt is not working. I just want my iTerm 2 back to the way it was...
Here is my .zshrc file and the prompt. It looks bad. How do I fix this?
It looks like you are using Oh-My-ZSH. In that case you should be able to restore at least the default settings with:
cp $HOME/.oh-my-zsh/templates/zshrc.zsh-template $HOME/.zshrc
This will of course overwrite your ~/.zshrc, but the first line is in the template anyway and the second line is a bash-styile definition for the shell prompt and has no place in a zsh configuration file.
After copying the template I would suggest having a look into the new ~/.zshrc to see, if there are any other settings you want to make.
If the cp command fails because it cannot find the source file, then you probably have somehow removed Oh-My-ZSH. In that case you can re-install it by following the instructions on OhMyZ.sh.

The above message is the error message I receive every time I open my terminal. I did create a backup of my bash profile. But essentially now I can no longer navigate anywhere I want to go using command line requests.
Any help would be much appreciated
If you have a backup, use an absolute path to the mv and cp commands to rename your broken file and restore the backup, both without depending on path lookup.
/bin/mv .bash_profile .bash_profile.broken
/bin/cp .bash_profile.backup .bash_profile
Close the current terminal window and open a new one, which should use your working, original .bash_profile to initialize PATH. Now you try to make the correct modification to your PATH.
oops. The easiest way to fix it would be to launch an editor with an absolute path. $PATH only specifies the locations in which the shell will search if told to execute a program relative (or no) path specified. The which program can search the path and shows the first executable found:
$ which vim
/usr/bin/vim
So if you're a vim user, you should be able to run /usr/bin/vim at the command line, and the path won't be relevant. Then you can fix your file in the editor. Looks like my osx machine also has nano if you'd prefer that editor. I don't think I installed it so it probably came shipped with osx I'm guessing:
$ which nano
/usr/bin/nano
If you want to revert to your backup, use cp, but specify it from its absolute position, /bin/cp:
$ /bin/cp first.txt second.txt
Obviously you'll want to change the file names on that one for it to work for you.
I was downloading the CakePHP framework for a project. Below the steps:
Installation
1) Install PHP 5.6 from: http://php-osx.liip.ch/
curl -s http://php-osx.liip.ch/install.sh | bash -s 5.6
2) add the updated PHP version to our path. So we edit .profile file
nano ~/.profile
Add into the file
export PATH= /usr/local/php5/bin:$PATH
Then hit Control + O to write out the file
Then hit Control + X to save the file
exit
Restart the Terminal
Now the terminal doesn't work as usually. I've tried to understand the shell concept and apply different solutions, but I can't even find the .profile file again.
I obtain errors like:
enter code here-bash: ls: command not found
Anybody can explain me what's wrong and the shell concept to properly understand shell (-bash)?
The problem is this:
export PATH= /usr/local/php5/bin:$PATH
You killed your PATH variable. You need to find a way to edit .profile file, and change that line to:
export PATH=$PATH:/usr/local/php5/bin
You could try editing with the following command (using vim):
/usr/bin/vim /Users/yourname/.profile
Or (using nano):
/usr/bin/nano /Users/yourname/.profile
Or just remove .profile file completely by doing /bin/rm /Users/yourname/.profile. Of course, in any case, you need to restart your terminal once you're done.
So I wanted to install MySQL on my MBP and I edited my bash_profile, added a path variable, however when I run echo $PATH from iTerm2 I get my path as:
Robs-MBP:~ Rob$ echo $PATH
/usr/local/mysql/bin
Ive tried a lot of commands and even used sudo and it just says command not found. My fear is that I have completely messed up, and now nothing works. Please help.
You've made a simple mistake: all you've done is reset the PATH env variable. To correctly do this, you should always add the existing PATH to the end of whatever you're adding. In you case:
PATH=/usr/local/mysql/bin:$PATH
To fix your problem from the terminal, you'll need to reset your PATH to somewhere with a text editor. I don't know where this is located on OSX, so you'll have to find it. After you know where your path should point, run:
$ export PATH=<YOUR_PATH_HERE>
Then edit your bashrc to include the original path as described above, and restart the terminal.
Alternatively, open .bashrc with a GUI text editor and make the change from there. Your PATH decleration should always end in :$PATH to include the PATH created by your system.
Recently I installed someone else .dotfiles and as excepted overwrited my configuration.
The thing is that I want to use my custom settings for my ZSH but I can't find .zshrc inside ~/, I have other .zshrc.files but editing none of these is working.
Also the dotfiles I've installed are in `~/.dotfiles but seems that none of these contains config.
Can someone please explain me how to edit the ZSH now, can I revert my old .zshrc?
Go to home directory typing cd
Type the command zsh and Press Enter
Select the option (2) Populate your ~/.zshrc with the configuration
recommended
by the system administrator and exit (you will need to edit
the file by hand, if so desired).
(You have to type "2" to select it and press enter)...
then all the files will be created on the directory..
I tried to change something in my bash_profile but I think I mistyped something. So I can not run any terminal commands. If I post "ls" command then I get
-bash: ls: command not found
Now I can not open bash_profile also. So what can I do here. I get the below path using echo command but there was some any other path. Please help.
echo $PATH: /usr/local/bin:/usr/local/bin:
But if I write /bin/ls it works.

This is the possible answer - And I solved it using nano editor
You messed up your PATH environment variable.
/bin/ls
works because you did not need PATH to find the 'ls' program. You can run ANY command by specifying its full path.
You need to re-edit your .bash_profile to either remove your PATH, or fix it. I do not know what editor you used to modify .bash_profile to begin with, but you can use
/usr/bin/nano
/usr/bin/vi (ONLY if you know vi/Vim)
/usr/bin/vim (ONLY if you know vi/Vim)
/usr/bin/emacs (I shutter to think about this)

Or you can just rename the current .bash_profile and start a new terminal session, then fix the renamed .bash_profile before putting it back in service
/bin/mv .bash_profile saved.bash_profile
