MacOS – Cannot open Terminal normally

bashmacosterminal

I tried to install opencv via homebrew, but I have done something wrong. I closed Terminal to restart it, however since then I can't open Terminal normally.

-bash: brew: command not found
Ys-MacBook-Air:/ hareentej22$

When I opened Terminal, I tried the above command lines, but none work. How can this be fixed?

edit : i run the command line as @allan mentioned and i get the following result .

Ys-MacBook-Air:~ hareentej22$ /bin/ls -la

Edit your ~/.bash_profile with nano replacing username with your actual profile username.

$ /usr/bin/nano /Users/username/.bash_profile

Delete the line(s) containing your PATH statement. Save and exit. When you restart your Terminal session, your path should be back to normal.

MacOS – OS X 10.10.5 – root user suddenly activated

The "Shared" folder is - depending on your system - automatically created or created by the system after establishing a second user account on your Mac (in your case probably the test user). Its purpose is the sharing of files between several user accounts.

Those files (and folders) may be personal data, Application Support files for all users or registration/licensing data.

Therefore the read and write bits are set for all users (BTW t is a sticky bit):

drwxrwxrwt   9 root   wheel    306B 16 Aug 22:30 Shared

The user folder of the root account is /var/root and contains the same default folders as a normal account.

After enabling the root user, the "new" user "Others" will be displayed in the login screen. This was done a "few months ago" as mentioned in your first EDIT section. There is no relation to the Update 10.10.5. You probably have done it yourself in the past or someone else who has admin access to your Mac.

The reason to be able to use your standard password with su is the identity of your password and the root password. If you change the password for root, you would have to enter this instead. If you then would like to su your admin user without knowing the root password, you would have to enter sudo su and your admin's password.

MacOS – terminal -bash: command not found

Modify the file .bash_profile with nano or another appropriate editor:

Replace:

export PATH=’/usr/local/bin:?? 
# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

by:

# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin:$PATH

Explanation:

The first line of your current .bash_profile

export PATH=’/usr/local/bin:??

modifies the standard value of $PATH given by /etc/paths from

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

to ’/usr/local/bin:?? - which is no valid path.

The fourth and fifth line of your current .bash_profile modifies $PATH to

/Library/Frameworks/Python.framework/Versions/2.7/bin:’/usr/local/bin:??

Since ’/usr/local/bin:? is no valid path the finally effective PATH is

/Library/Frameworks/Python.framework/Versions/2.7/bin

which completely breaks your standard PATH. You can still execute all executables in the above directories but you can't omit the superior directories (e.g. to execute nano you have to enter /usr/bin/nano instead of nano).
