no, it is in text diff mode, I want to show in graphically way, I want to show the diff one by one in kdiff3.

Hello,

if I understand your problem correctly, git log -p hello.txt may show (somewhat) what you need.

Best,

     Hi, I am trying to visually show a file change history.
     I have a file, named hello.txt, and 3 commits on it, they are:

    _ 1b0e691e55caa8fd2b5dd6902f77c406fb68e648__
    __ d058c095f7e98a7ebe943c18f87ef087c723bb9f__
    __ c4d1769183ab6d852c624e71e6a0ca00dc3b6d13__
    _
     Please note: they might not be continuous.
     The way to find all the commits on this file is by following command:
    _git log --follow hello.txt|awk '/commit/{print $2}'_
     Now, I want to show every visual diff of the 3, against their
    respective parent.
     Let's take 1b0e691e55caa8fd2b5dd6902f77c406fb68e648 as example:
     The following command will give me a view on the commit details
    on this file, and since I have configured kdiff3 as the difftool,
    so it will pop up a kdiff3 windows to display the differences.
    _ git difftool 1b0e691e55caa8fd2b5dd6902f77c406fb68e648^! hello.txt_
     So, I continue to use a while loop to try to see all the 3
    commits diff view
    _ git log --follow hello.txt|awk '/commit/{print $2}'|while read
    ss; do git difftool $ss^! hello.txt; done_

     But, when I run my script , only these two commits are displayed,

    _ 1b0e691e55caa8fd2b5dd6902f77c406fb68e648__
    __ c4d1769183ab6d852c624e71e6a0ca00dc3b6d13__
    _
     this middle one

    _ d058c095f7e98a7ebe943c18f87ef087c723bb9f_

     is somehow skipped, I guess it is because the ^! operator.
     But really, I don't know why the middle commit is skipped, and
    could someone help me to find out why my script not work?
     My intention is just to show the file change history in a visual
    tool, for example my favorite one: kdiff3,
     Or any alternative solution would also be greatly appreciated.

    The problem with your question is that you presented a solution without
    clearly explaining your objective.

    Could you please explain in simple words what are you trying to achieve?
    I mean, like in
    1) I have a commit-ish.  Let's call it "abc123".
    2) Given it, I'd like to have kdiff3 popped up displaying difference
        between such and such commits.
    3) ...

    In the meantime, does `git log --patch --follow -- path/to/file`
    do what you want (in text mode)?

    After doing `git config --global core.ui auto` diffs rendered in the
    console look no less understandable than those presented by a graphical
    tool IMO.  Well, unless you have insanely long lines in your files
    while having small terminal window.
