Strange output of git diff to file in Ubuntu

Question

Ubuntu 13.04. I want to create a patch and there is no problem when I'm using Netbeans or other IDE but when I run in command line:

git diff > 1.patch

and then

cat 1.patch

output looks like this:

Answer 1

It's colorized. <kbd>Esc</kbd>[36m is an ANSI escape sequence for a foreground color change.

1. Disable color

git diff --color=never

2. Or change the config

git config color.ui auto

This results in .git/config having:

[color]
    ui = auto

auto indicates that color is automatically enabled when output is to a terminal, but not if output is to a file/pipe.

3. Fixing existing patches

Look at AnsiFilter to remove ANSI escape sequences from existing patch files.

Answer 2

I follow this link enter link description here to see color:

$ export LESS="-eirMX"

You may need to edit .profile or .bashrc to permanently set environmental variables. For straight forward, all you need to do is to append the above line to one of the 3 following files:

~/.profile
~/.bash_profile
/etc/profile 

Answer 3

你可以尝试一下，它对我有用：

git config --global color.diff auto
