ZSH Mac Mavericks $PATH variable is corrupt - macos

For some reason, I am getting all sorts of weird behavior in terminal, I think it's related to my $PATH variable.
If I run this command:
echo $PATH
it outputs this
/Applications/MAMP/bin/php/php5.4.10/bin:/Applications/MAMP/bin/php/php5.4.10/bin:/Applications/MAMP/bin/php/php5.4.10/bin:/Applications/MAMP/bin/php/php5.4.10/bin:/Applications/MAMP/bin/php/php5.4.10/bin...........
How do I reset it back to what it should be?

It sounds like your MAMP install has added something to your login script(s), which is adding itself to your PATH repeatedly. Check your ~/.zshrc file for suspicious lines.

OSX Terminal $PATH strange characters

I have encountered some strange characters in Terminal's $PATH variable.
$ echo $PATH
/opt/local/bin:...(many similar entries)...:/usr/local/git/bin??n’export
??n’export is what I'm talking about. How do I remove it? I looked in .bacshrc, .bash_profile and similar files, but everything seemed normal there. Problem is that I can't install some new programs with "broken" $PATH.
I'm using bash in Terminal version 2.7.1 and macOS Sierra — Thanks in advance.
The following
perl -e 'printf q{export %s="%s";},$_,join(":",grep{-d $_&&!$seen{$_}++}split/:/,$ENV{$_}), $_ for(qw(PATH))'
will generate for you an new export PATH=..... line, but with cleaned elements. (e.g. no duplicate entries, and removed all nonexiststent directories).
you should copy and paste the result into your $HOME/.profile instead of the existing PATH line.
Problem solved. Strange entries came from /etc/profile file.

Terminal commands can not be found OSX

A majority of terminal commands don't work, for example .
ls
sudo
vi
with the error -bash: ls: command not found my path is echo $PATH
“/Users/username/usr/local/bin I get the feeling that “ should not be there but not sure how edit it.
What should the path be and how do I get the path to stay the same?
You need to add more paths to your $PATH variable. Try running whereis ls and check where is the binary of the command.
You can add more paths like this: export PATH=$PATH:NEW_PATH
I had a similar experience recently where a lot of my terminal commands were not being found despite being clearly saved in my bash_profile. After lengthy process of elimination I realised that the issue was caused when I tried to export a new path. The error that I had made was putting a space in the command. So I had to change
export SOMETHING = /path/to/something.apk to
export SOMETHING=/path/to/something.apk
So I would recommend you check all your path declarations to ensure you don't have any white spaces. Also don't forget to source your bash_profile or what ever type of command line shell you use.

-bash: sudo: command not found Mac OS X (EC2 CLI prob?)

Getting the error:
-bash: sudo: command not found
echo $PATH outputs PATH:EC2_HOME/bin
I'm running Mac OSX 10.8.3
That seems wrong even for a n00b like me.
How do I fix my $PATH and return my computer to it's former self?
As stated in the comments the right files to set up your $PATH variable are: ~/.profile or ~/.bash_profile
export PATH=/usr/bin:/usr/sbin:/bin:/usr/local/bin:/sbin:/opt/x11/bin:$PATH
In this way when you re-enter in the console your PATH will work fine.
You can add other directories to your $PATH as you like.
If you just copy and past that line in an active console you just set the PATH variable temporary, when you logout and login again you will loose your path, so add it in your ~/.bashrc file.
I'm not sure how you've managed to get into that state, though this article explains how you can set your path.
If it helps, the output from my echo $PATH is: -
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin
go to shell
choose new command
put this : sudo vim .bash_profile
then put : export PATH=/usr/bin:/usr/sbin:/bin:/usr/local/bin:/sbin:/opt/x11/bin:$PATH
This worked for me:
echo $PATH
Followed by:
export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"

Terminal in OSX Lion looks different after unknown command

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.

In Mac OSX 10.5, it can't find my Terminal commands sudo, find, etc

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/b‌​in
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
