When running git difftool I am being prompted for file diff, even though I have prompt = false in my .gitconfig file.
Snippet from .gitconfig
[diff]
tool = p4mergetool
renames = copies
mnemonicprefix = true
[difftool "p4mergetool"]
cmd = /Applications/p4merge.app/Contents/Resources/launchp4merge "$LOCAL" "$REMOTE"
keepBackup = false
keepTemporaries = false
trustExitCode = false
prompt = false
My .gitconfig entries were based on this answer on the Ask Different exchange.
macOS Terminal Output (bash)
$ git difftool factory-test HEAD -- $(git difftool factory-test HEAD --name-only *.c *.h)
Viewing (1/13): 'factory_test/config/sl_spidrv_usart_spidrv_config.h'
Launch 'p4mergetool' [Y/n]? Y
Viewing (2/13): 'factory_test/app.c'
Launch 'p4mergetool' [Y/n]?
How do I get the prompt suppression to take effect?
My version infos:
p4merge (Rev. Helix Merge/MACOSX1015X86_64/2021.1/2085655)
git (git version 2.31.1)

Here is the solution:
[diff]
tool = p4mergetool
[difftool]
prompt = false
[difftool "p4mergetool"]
cmd = /Applications/p4merge.app/Contents/Resources/launchp4merge "$LOCAL" "$REMOTE"
keepBackup = false
keepTemporaries = false
trustExitCode = false
I am trying to add the following aliases in ubuntu
alias l=log --pretty=format:"%C(yellow)%h\\ %ad%Cred%d\\ %Creset%s%Cblue\\ [%cn]" --decorate --date=short
$ source ~/.aliases
bash: alias: --decorate: not found
bash: alias: --decorate: not found
bash: alias: --numstat: not found
I could use this command outside with git
I am not so sure why? Can someone help me? I tried googling but I did not go far with it. I do not know bash so much.
This is bit older question but it is very important to understand and create git alias as this will save lot of time of yours.
In your question you are close to answer just a silly mistake done is you are trying to create alias using script.
Alias needs to be defined in .gitconfig file. Not just alias but all config part like
[core], [color], [pack], [help], [alias] etc
I would like to share some basic and useful alias with you to have things handy and you can change it further per your need and daily usage
[alias]
lg = log -p
lol = log --graph --decorate --pretty=oneline --abbrev-commit
lola = log --graph --decorate --pretty=oneline --abbrev-commit --all
st = status
co = checkout
ci = commit -a -m
br = branch
ls = ls-files
po = push origin
f = fetch
p = pull
delete = branch -d master
com = checkout master
cob = checkout -b
unstage = reset HEAD
url = remote set-url origin
ign = ls-files -o -i --exclude-standard
cp = cherry-pick
You can also create an alias for a combination of multiple git commands in a single one as, for instance:
rdev = !git checkout dev && git pull && git checkout - && git rebase dev
Let me know if any other understanding needed.
You are almost there. You just need to put the alias in the right file. Because Git doesn’t automatically infer your command if you type it in partially, you can easily set up an alias for each command using git config like so:
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit
git config --global alias.st status
And then you use it the aliases like: git ci, git co, git br, git st in any repo.
You can also run an external command through an alias. In that case, you start the command with a ! character. This is useful if you write your own tools that work with a Git repository:
git config --global alias.visual '!gitk'
You might have also noticed that the config command takes in several parameters (like the --global one). If we look at the docs man git config:
For writing options: write to global ~/.gitconfig file rather than the repository .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the ~/.gitconfig file doesn’t.
For reading options: read only from global ~/.gitconfig and from $XDG_CONFIG_HOME/git/config rather than from all available files.
See also the section called “FILES”.
There is also --system, which writes to /etc/gitconfig, --local, for the local repo .git/gitconfig, and --worktree, which is similar to --local.
But you can just directly edit the files themselves. It will look similar to this:
# in ~/.gitconfig
[alias]
lg = log --all --stat --pretty=oneline --graph --format='%h %d %an %cr %s' --oneline
l = log --all --stat --graph --format='%h %d %an %cr %s'
up = pull --rebase
br = branch --verbose -a
sfp = push --force-with-lease
You should set the alias in your git aliases and use it from the command line
You can directly edit the configuration file or do it from CLI:
Git Alias
Use the git config --global alias.<name> in order to add git alias
git config --global alias.l 'log --pretty=format:"%C(yellow)%h\\ %ad%Cred%d\\ %Creset%s%Cblue\\ [%cn]" --decorate'
now you should be able to use it with: git l
Ubuntu Alias
If you wish to add an alias to your shell in Ubuntu:
alias gitl='git l'
It used to work but after changing my laptop, it is not recognized anymore. Any help is highly appreciated!
Here is what I tried using Git Bash (git version 2.16.2.windows.1):
$ git config --list --show-origin
...
file:"C:\\Git\\mingw64/etc/gitconfig" difftool.kdiff3.cmd='C:/Program Files/KDiff3/kdiff3' $LOCAL $REMOTE
file:"C:\\Git\\mingw64/etc/gitconfig" difftool.kdiff3.keepbackup=false
file:"C:\\Git\\mingw64/etc/gitconfig" difftool.kdiff3.trustexitcode=false
file:"C:\\Git\\mingw64/etc/gitconfig" merge.conflictstyle=diff3
...
I copied the old working config file. But then:
$ git difftool master devSQC
This message is displayed because 'diff.tool' is not configured.
See 'git difftool --tool-help' or 'git help config' for more details.
'git difftool' will now attempt to use one of the following tools:
kompare emerge vimdiff
...
$ git difftool --tool-help
'git difftool --tool=<tool>' may be set to one of the following:
vimdiff
vimdiff2
vimdiff3
user-defined:
kdiff3.cmd 'C:/Program Files/KDiff3/kdiff3' $LOCAL $REMOTE
The following tools are valid, but not currently available:
araxis
bc
bc3
codecompare
deltawalker
diffmerge
diffuse
ecmerge
emerge
examdiff
gvimdiff
gvimdiff2
gvimdiff3
kdiff3
kompare
meld
opendiff
p4merge
tkdiff
winmerge
xxdiff
Some of the tools listed above only work in a windowed
environment. If run in a terminal-only session, they will fail.
$ git difftool -t=kdiff3 master devSQC
Viewing (1/61): '.gitignore'
Launch '_kdiff3' [Y/n]? y
Unknown merge tool _kdiff3
fatal: external diff died, stopping at .gitignore
You have to change this line:
git difftool -t=kdiff3 master devSQC
by either:
git difftool -t kdiff3 master devSQC
or:
git difftool --tool=kdiff3 master devSQC
Usually, short arguments like -t are followed by a space character. And long options like --tool are followed by a =. It is kind of a convention.
I'm trying to configure DiffMerge for git to use for difftool and mergetool. I used following command:-
The following commands in a Command Prompt window will update your .gitconfig to configure GIT use DiffMerge:
C:\> git config --global diff.tool diffmerge
C:\> git config --global difftool.diffmerge.cmd
"C:/Program\ Files/SourceGear/Common/DiffMerge/sgdm.exe \"$LOCAL\"
\"$REMOTE\""`
If I check the content of .gitconfig it has following:-
` [diff]
tool = diffmerge
[mergetool "diffmerge"]
cmd = C:/Program\\ Files/SourceGear/Common/DiffMerge/sgdm.exe -merge -result=\"\" \"\" \"\" \"\"
trustExitCode = true
[merge]
tool = diffmerge
[difftool "diffmerge"]
cmd = C:/Program\\ Files/SourceGear/Common/DiffMerge/sgdm.exe \"\" \"\"
[core]
autocrlf = true
excludesfile = C:\\Users\\dev\\Documents\\gitignore_global.txt
[user]
name = DESKTOP - VAFJEG6\\dev
email = madsum.isalm2#gmail.com `
If I try $ git config --global --list:-
diff.tool=diffmerge
mergetool.diffmerge.cmd=C:/Program\
Files/SourceGear/Common/DiffMerge/sgdm.exe -merge -result="" "" "" ""
mergetool.diffmerge.trustexitcode=true
merge.tool=diffmerge
difftool.diffmerge.cmd=C:/Program\
Files/SourceGear/Common/DiffMerge/sgdm.exe "" ""
core.autocrlf=true
core.excludesfile=C:\Users\dev\Documents\gitignore_global.txt
user.name=DESKTOP-VAFJEG6\dev
user.email=madsum.isalm2#gmail.com`
If I try git $ git difftool it showed this dialog:-
What is wrong? How to configure it correctly?
The $LOCAL/$REMOTE mentioned in the doc must have been interpreted by the shell (if typed from a git bash instead of a CMD session) and replaced by "".
Edit directly the global config (git config --global --edit) and add the missing elements to obtain:
[difftool "DiffMerge"]
cmd = 'C:/Program Files/SourceGear/Common/DiffMerge/sgdm.exe' "$LOCAL" "$REMOTE"
[merge]
tool = DiffMerge
[mergetool "DiffMerge"]
cmd = 'C:/Program Files/SourceGear/Common/DiffMerge/sgdm.exe' -merge -result="$PWD/$MERGED" "$PWD/$LOCAL" "$PWD/$BASE" "$PWD/$REMOTE"
trustExitCode = true
I've tried msysGit and Git on Cygwin. Both work just fine in and of themselves and both run gitk and git-gui perfectly.
Now how the heck do I configure a mergetool? (Vimdiff works on Cygwin, but preferably I would like something a little more user-friendly for some of our Windows-loving coworkers.)
To follow-up on Charles Bailey's answer, here's my git setup that's using p4merge (free cross-platform 3way merge tool); tested on msys Git (Windows) install:
git config --global merge.tool p4merge
git config --global mergetool.p4merge.cmd 'p4merge.exe \"$BASE\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\"'
or, from a windows cmd.exe shell, the second line becomes :
git config --global mergetool.p4merge.cmd "p4merge.exe \"$BASE\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\""
The changes (relative to Charles Bailey):
added to global git config, i.e. valid for all git projects not just the current one
the custom tool config value resides in "mergetool.[tool].cmd", not "merge.[tool].cmd" (silly me, spent an hour troubleshooting why git kept complaining about non-existing tool)
added double quotes for all file names so that files with spaces can still be found by the merge tool (I tested this in msys Git from Powershell)
note that by default Perforce will add its installation dir to PATH, thus no need to specify full path to p4merge in the command
Download: http://www.perforce.com/product/components/perforce-visual-merge-and-diff-tools
EDIT (Feb 2014)
As pointed out by #Gregory Pakosz, latest msys git now "natively" supports p4merge (tested on 1.8.5.2.msysgit.0).
You can display list of supported tools by running:
git mergetool --tool-help
You should see p4merge in either available or valid list. If not, please update your git.
If p4merge was listed as available, it is in your PATH and you only have to set merge.tool:
git config --global merge.tool p4merge
If it was listed as valid, you have to define mergetool.p4merge.path in addition to merge.tool:
git config --global mergetool.p4merge.path c:/Users/my-login/AppData/Local/Perforce/p4merge.exe
The above is an example path when p4merge was installed for the current user, not system-wide (does not need admin rights or UAC elevation)
Although ~ should expand to current user's home directory (so in theory the path should be ~/AppData/Local/Perforce/p4merge.exe), this did not work for me
Even better would have been to take advantage of an environment variable (e.g. $LOCALAPPDATA/Perforce/p4merge.exe), git does not seem to be expanding environment variables for paths (if you know how to get this working, please let me know or update this answer)
setting mergetool.p4merge.cmd will not work anymore since Git has started trying to support p4merge, see libexec/git-core/git-mergetool--lib.so we just need to specify the mergetool path for git,for example the p4merge:
git config --global mergetool.p4merge.path 'C:\Program Files\Perforce\p4merge.exe'
git config --global merge.tool p4merge
Then it will work.
I'm using Portable Git on WinXP (works a treat!), and needed to resolve a conflict that came up in branching. Of all the gui's I checked, KDiff3 proved to be the most transparent to use.
But I found the instructions I needed to get it working in Windows in this blog post, instructions which differ slightly from the other approaches listed here. It basically amounted to adding these lines to my .gitconfig file:
[merge]
tool = kdiff3
[mergetool "kdiff3"]
path = C:/YourPathToBinaryHere/KDiff3/kdiff3.exe
keepBackup = false
trustExitCode = false
Working nicely now!
Under Cygwin, the only thing that worked for me is the following:
git config --global merge.tool myp4merge
git config --global mergetool.myp4merge.cmd 'p4merge.exe "$(cygpath -wla $BASE)" "$(cygpath -wla $LOCAL)" "$(cygpath -wla $REMOTE)" "$(cygpath -wla $MERGED)"'
git config --global diff.tool myp4diff
git config --global difftool.myp4diff.cmd 'p4merge.exe "$(cygpath -wla $LOCAL)" "$(cygpath -wla $REMOTE)"'
Also, I like to turn off the prompt message for difftool:
git config --global difftool.prompt false
git mergetool is fully configurable so you can pretty much chose your favourite tool.
The full documentation is here: http://www.kernel.org/pub/software/scm/git/docs/git-mergetool.html
In brief, you can set a default mergetool by setting the user config variable merge.tool.
If the merge tool is one of the ones supported natively by it you just have to set mergetool.<tool>.path to the full path to the tool (replace <tool> by what you have configured merge.tool to be.
Otherwise, you can set mergetool.<tool>.cmd to a bit of shell to be eval'ed at runtime with the shell variables $BASE, $LOCAL, $REMOTE, $MERGED set to the appropriate files. You have to be a bit careful with the escaping whether you directly edit a config file or set the variable with the git config command.
Something like this should give the flavour of what you can do ('mymerge' is a fictional tool).
git config merge.tool mymerge
git config merge.mymerge.cmd 'mymerge.exe --base "$BASE" "$LOCAL" "$REMOTE" -o "$MERGED"'
Once you've setup your favourite merge tool, it's simply a matter of running git mergetool whenever you have conflicts to resolve.
The p4merge tool from Perforce is a pretty good standalone merge tool.
For beyond compare on Windows 7
git config --global merge.tool bc3
git config --global mergetool.bc3.path "C:\Program Files (x86)\Beyond Compare 3\BCompare.exe"
It seems that newer git versions support p4merge directly, so
git config --global merge.tool p4merge
should be all you need, if p4merge.exe is on your path. No need to set up cmd or path.
I found two ways to configure "SourceGear DiffMerge" as difftool and mergetool in github Windows.
The following commands in a Command Prompt window will update your .gitconfig to configure GIT use DiffMerge:
git config --global diff.tool diffmerge
git config --global difftool.diffmerge.cmd 'C:/Program\ Files/SourceGear/Common/DiffMerge/sgdm.exe \"$LOCAL\" \"$REMOTE\"'
git config --global merge.tool diffmerge
git config --global mergetool.diffmerge.cmd 'C:/Program\ Files/SourceGear/Common/DiffMerge/sgdm.exe -merge -result=\"$MERGED\" \"$LOCAL\" \"$BASE\" \"$REMOTE\"'
[OR]
Add the following lines to your .gitconfig. This file should be in your home directory in C:\Users\UserName:
[diff]
tool = diffmerge
[difftool "diffmerge"]
cmd = C:/Program\\ Files/SourceGear/Common/DiffMerge/sgdm.exe \"$LOCAL\" \"$REMOTE\"
[merge]
tool = diffmerge
[mergetool "diffmerge"]
trustExitCode = true
cmd = C:/Program\\ Files/SourceGear/Common/DiffMerge/sgdm.exe -merge -result=\"$MERGED\" \"$LOCAL\" \"$BASE\" \"$REMOTE\"
As already answered here (and here and here), mergetool is the command to configure this. For a nice graphical frontend I recommend kdiff3 (GPL).
I had to drop the extra quoting using msysGit on windows 7, not sure why.
git config --global merge.tool p4merge
git config --global mergetool.p4merge.cmd 'p4merge $BASE $LOCAL $REMOTE $MERGED'
If you're doing this through cygwin, you may need to use cygpath:
git config --global merge.tool p4merge
git config --global mergetool.p4merge.cmd 'p4merge `cygpath -w $BASE` `cygpath -w $LOCAL` `cygpath -w $REMOTE` `cygpath -w $MERGED`'
Bah, this finally worked for me (Windows 7 + Cygwin + TortoiseMerge):
In .git/config:
cmd = TortoiseMerge.exe /base:$(cygpath -d \"$BASE\") /theirs:$(cygpath -d \"$REMOTE\") /mine:$(cygpath -d \"$LOCAL\") /merged:$(cygpath -d \"$MERGED\")
Thanks to previous posters for the tip to use cygpath!
i use an app called WinMerge ( http://winmerge.org/ )
info from their manual ( http://manual.winmerge.org/CommandLine.html )
this is the bash script i use from the mergetool directive via .gitconfig
#!/bin/sh
# using winmerge with git
# replaces unix style null files with a newly created empty windows temp file
file1=$1
if [ "$file1" == '/dev/null' ] || [ "$file1" == '\\.\nul' ] || [ ! -e "$file1" ]
then
file1="/tmp/gitnull"
`echo "">$file1`
fi
file2=$2
if [ "$file2" == '/dev/null' ] || [ "$file2" == '\\.\nul' ] || [ ! -e "$file2" ]
then
file2="/tmp/gitnull"
`echo "">$file2`
fi
echo diff : $1 -- $2
"C:\Program files (x86)\WinMerge\WinMergeU.exe" -e -ub -dl "Base" -dr "Mine" "$file1" "$file2"
basically the bash accounts for when the result of the diff in an empty file and creates a new temp file in the correct location.
You may want to add these options too:
git config --global merge.tool p4mergetool
git config --global mergetool.p4merge.cmd 'p4merge $BASE $LOCAL $REMOTE $MERGED'
git config --global mergetool.p4mergetool.trustExitCode false
git config --global mergetool.keepBackup false
Also, I don't know why but the quoting and slash from Milan Gardian's answer screwed things up for me.
If anyone wants to use gvim as their diff tool on TortoiseGit, then this is what you need to enter into the text input for the path to the external diff tool:
path\to\gvim.exe -f -d -c "wincmd R" -c "wincmd R" -c "wincmd h" -c "wincmd J"
For IntelliJ IDEA (Community Edition) 3-way git mergetool configuration in Windows environment (~/.gitconfig)
Cygwin
[mergetool "ideamerge"]
cmd = C:/Program\\ Files\\ \\(x86\\)/JetBrains/IntelliJ\\ IDEA\\ Community\\ Edition\\ 14.1.3/bin/idea.exe merge `cygpath -wa $LOCAL` `cygpath -wa $REMOTE` `cygpath -wa $BASE` `cygpath -wa $MERGED`
[merge]
tool = ideamerge
Msys
[mergetool "ideamerge"]
cmd = "/c/Program\\ Files\\ \\(x86\\)/JetBrains/IntelliJ\\ IDEA\\ Community\\ Edition\\ 14.1.3/bin/idea.exe" merge `~/winpath.sh $LOCAL` `~/winpath.sh $REMOTE` `~/winpath.sh $BASE` `~/winpath.sh $MERGED`
[merge]
tool = ideamerge
The ~/winpath.sh is to convert paths to Windows on msys and is taken from msys path conversion question on stackoverflow
#! /bin/sh
function wpath {
if [ -z "$1" ]; then
echo "$#"
else
if [ -f "$1" ]; then
local dir=$(dirname "$1")
local fn=$(basename "$1")
echo "$(cd "$dir"; echo "$(pwd -W)/$fn")" | sed 's|/|\\|g';
else
if [ -d "$1" ]; then
echo "$(cd "$1"; pwd -W)" | sed 's|/|\\|g';
else
echo "$1" | sed 's|^/\(.\)/|\1:\\|g; s|/|\\|g';
fi
fi
fi
}
wpath "$#"
For kdiff3 you can use:
git config --global merge.tool kdiff3
git config --global mergetool.kdiff3.path "C:/Program Files/KDiff3/kdiff3.exe"
git config --global mergetool.kdiff3.trustExitCode false
git config --global diff.guitool kdiff3
git config --global difftool.kdiff3.path "C:/Program Files/KDiff3/kdiff3.exe"
git config --global difftool.kdiff3.trustExitCode false
To setup p4merge, installed using chocolatey on windows for both merge and diff, take a look here:
https://gist.github.com/CamW/88e95ea8d9f0786d746a
If you're having problems opening p4merge from SourceTree look for you local configuration file named config under MyRepo.git and delete any merge configuration.
In my case it was trying to open Meld which I just uninstalled
