@cb-pradeep Thank you for that. Working for me too now.
hi @cb-pradeep can you explain me the above command and can used for email notifications as well ?
Thanks a million @stopyoukid for the script and it saved my day.
Commands used:
Approach1: (discreet commands)
1. git diff branch1 branch 2 >> gitdiff.txt
2. cat gitdiff.txt | <absolute path to diff2html.sh>/diff2html.sh
Approach2: (combine both commands)
git diff branch1 branch 2 | <absolute path to diff2html.sh>/diff2html.sh
Here are few errors I encounted on ubuntu before I became successful.
- Function not found
- Syntax error: redirection unexpected
Both the errors are encounted while running the script using command sh diff2html.sh which forces ubuntu to choose dash instead of bash. Instead use the command <absolute path to diff2html.sh>/diff2html.sh
nice, works well

git diff $compareBranch -- $argument | sh $script_folder/diff2html.sh > $diffHtmlFilePath.This worked for me
