MATLAB: MATLAB warns about terminal not being fully functional when using System command (!)

MATLAB

I try to use Bash commands (git) under Linux in MATLAB using the system command or its operator (!).

The command 'git log -1' yields the following behavior. How can I solve this?

The message says the following:

WARNING: terminal is not fully functional

This happens because when MATLAB's system command executes it uses its own environment and not the environment that MATLAB was first started from.

The following works because MATLAB can see and set the environment variable before running the git command.

system('TERM=ansi; git <any command>')

MATLAB: How to use “system” command without MATLAB environment

You can override an environment variable in the "system" command.

For example, on a Windows platform, the following code sets the PATH variable to "myPath", then calls the "system" command "dosCommand" with that value.

>> system(['set PATH=' myPath ' && ' dosCommand])

MATLAB: How to set a system-wide environment variable from within MATLAB

This is a limitation of the Windows operating system. Environment variables that are set from within a process, instead of being set through the control panel, are visible only to that process.

A possible workaround would be to use ActiveX functionality, as implemented in the attached file. Please note that setting a system-wide variable this way requires a restart in order for the changes to take effect.

As another possible workaround, Microsoft offers a tool called "setx" which allows you to set system-wide environment variables.This command is available in Windows versions later than Windows XP Service Pack 2 and Windows 2000. More information on the "setx" command can be found at:

Here is an example how to use it from within MATLAB:

>> !setx my_var some_value
This way of setting system-wide environmental variable does not require a restart of Windows or user re-logging on. However, note that if you use the Windows command window and
the "set" command to view the environmental variables, you will need to restart the command window to see the change.
