CygWin environment TortoiseMerge shows error

Asked By 0 points N/A Posted on -


The CygWin is an environment for Windows which makes it possible to port software running on POSIX systems such as Linux and Unix. I created a unified diff but it showed up an error as shown below.

Error message:

The line “Index: “was not found!

Either this is not a diff file or the diff is empty.

CygWin environment TortoiseMerge shows error


Hi Harriet,
The error is because TortiseMerge is not installed in the correct file path.
The solution to it is:
1) Go to 'MyComputer' > 'Properties' > 'Advanced' > 'EnvironmentVariables' > 'System Variables':Path
2) From Commannd Prompt, type following commands:
a) git config –replace –global diff.tool tortisemerge
b) git config –replace –global difftool.diffmerge.cmd "TortiseMerge.exe -base:"$BASE"-theirs:"REMOTE"-mine:"$LOCAL"-merged:"$MERGED"
c) git config –replace –global difftool.prompt false
3) Restart the system after executing the above commands and the error is resolved
