Unable to delete Cygwin from PATH environment variable

Unable to delete Cygwin from PATH environment variable

[Tanya Sandoval]

Hi,

I recently had to reinstall Cygwin and in doing so, I have ran into a
problem with some application because Cygwin seems to be appended to
my PATH environment variable. I have tried to remove this by following
these instructions https://www.java.com/en/download/help/path.xml but
something strange happens. If I look at the value of Path under
'Environment Variables', Cygwin is not there; however if I type PATH
in cmd.exe, I see Cygwin gets appended at the end of the PATH. Can you
please help me to know to remove Cygwin from the PATH?

As an example, this is what I see in the Environmental Variables
window Path value:

Path=C:\Program Files (x86)\Intel\iCLS Client\;C:\Program
Files\Intel\iCLS
Client\;c:\Oracle\11g_R2_x64\Administrator\11.2.0\client_1\bin;C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;%systemroot%\System32\WindowsPowerShell\v1.0\;C:\Program
Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files
(x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program
Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files
(x86)\Intel\Intel(R) Management Engine
Components\IPT;%systemroot%\System32\WindowsPowerShell\v1.0\;C:\Apps\Anaconda3;C:\Apps\Anaconda3\Scripts;C:\Apps\Anaconda3\Library\bin

And this is what I see in cdm.exe:

>PATH
PATH=C:\Program Files (x86)\Intel\iCLS Client\;C:\Program
Files\Intel\iCLS Clien
t\;c:\Oracle\11g_R2_x64\Administrator\11.2.0\client_1\bin;C:\ProgramData\Oracle\
Java\javapath;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS
\System32\WindowsPowerShell\v1.0\;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:
\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files
(x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Int
el(R) Management Engine Components\IPT;C:\Program Files
(x86)\Intel\Intel(R) Man agement Engine
Components\IPT;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\App
s\Anaconda3;C:\Apps\Anaconda3\Scripts;C:\Apps\Anaconda3\Library\bin;C:\blp\DAPI;
C:\blp\DAPI\DDE;C:\Apps\cygwin64\bin

As you can see, I have Cygwin in the second case, whereas I don't have
it on the first case.

Many thanks for your help!

Best,
Tanya

If you mean PATH in a terminal, then you, or the terminal program
(mintty perhaps) are running a shell (bash).  If you did not mean in a
terminal, then also look at the user's environment vars (there are 2
sets: global, and local).

The shell, depending on the parameters which it was invoked with,
usually runs one of its configuration files (bash runs either .bashrc,
or .bash_profile, also /etc/profile), which usually is what sets the
environment you see inside the terminal+shell.

You can direct the shell not to read config files (bash --noprofile
--norc), or change all the possible config files, which is much more
involved, and affect every invocation of the shell... which is not what
you probably want.

Hope this helps.

There are two places to add environment variables:
the System Variables and the User Variables.
See https://www.copsmodels.com/gpsetenv.htm
for screenshots.
Did you check both?  (Also, it's possible the list
might need scrolling to see the end.)

Also, changes only show up when you start a new cmd.exe,
maybe you were looking at a cmd.exe window that had
been started before the change.

Thanks for your help - your solution worked! Indeed I had cygwin added
to my user's path and not my system's path, and I was looking for it
in the system's path.

Best,
Tanya
