For the past few days, we are seeing a strange behavior on executing Git commands.
Command executed: git show 08fcf54adc7bbb75a54b14625fdeea7608d44a23 > sample.patch
On opening the file sample.patch through vi editor, we are seeing a lot of special characters; a sample output file looks like:
^[[33mcommit 08fcf54adc7bbb75a54b14625fdeea7608d44a23^[[m

Note1: The issue is seen only for one particular user(on Ubuntu server). So possibly it looks like the configuration issue with Git or maybe vi editor.
Note2: The normal file redirection seems to be working fine. Example cat abc > xyz, the contents are copied properly with no special characters
Any help would be highly appreciated.

Check the Git color settings. It looks like they're set to true for this particular user, but you want to use auto instead.
The characters you're seeing are color codes for the terminal. With a color setting of auto, they shouldn't be visible when piping to vi.
Check out a more detailed question/answer here: https://unix.stackexchange.com/questions/44266/how-to-colorize-output-of-git
Git Documentation: http://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration#Colors-in-Git
The default value is auto, so it looks like the user in question has a local configuration overriding the default values.
