Hi there, Can I change the grep command called by git with alternative tools, such as ug [1]? Say in the following command: $ git grep -i jobflow I tried to replace grep with ug, but failed as follows: $ git ug -i jobflow git: 'ug' is not a git command. See 'git --help'. The most similar command is gui [1] https://github.com/Genivia/ugrep Regards, Zhao -- Assoc.
