A more friendly way to remove changes than git reset is git revert commithash, which will find all the changes made in a previous commit and remove them while keeping all the work in between.However, it is bad practice to reset commits that have already been pushed to the public repository. If you want to reflect the reset in your working files as well use git reset commithash -hard.This will effectively uncommit a change in your local repository, but won't change your working files. git reset HEAD~ x where x is the number of commits to backtrack to or git reset commithash.Reset, Revert, Checkout for undoing mistakes To rebase your branch: git rebase master. ![]() Instead of fixing conflicts when you merge two branches, you can rebase the branch you are working on before you merge so that you can have a clean merge later on.When there are no more conflicts, git merge nameofbranch will work.By clicking save, the document will reflect each decision you made when choosing winners. Next to each conflict, click on which branch should win.p4merge will show a three-way comparison between branchA, branchB, and their common ancestor.During conflicts, enter git mergetool and p4merge will run automatically (after following the procedure in the section).To download p4merge see the section below.Difftools/mergetools are very useful for this process.To see differences between branches, use git diff branchA branchB.Upon merging the two conflicting branches, someone is going to have to sit down and choose which of the changes to keep. When two branches contain changes to the same work, meaning two people worked on the same document and one person deleted or altered the same lines that the other altered, you have a conflict.Confirm it is gone using git branch -list. Now that you are done, use git branch -d nameofbranch to get rid of the branch you are done with because you don't need it anymore.Once you are done working on the branch, use git checkout master to switch back to the master branch and use git merge nameofbranch to merge the two back together. Do some work on your new branch, and add and commit changes.Confirm you are on the new branch by using git branch -list, the one with an asterisk next to it is the branch you are currently on. Alternatively, use git checkout -b nameofbranch to create and checkout the branch at the same time. To do this, use git branch nameofbranch, then git checkout nameofbranch to switch to that branch.It is best practice to branch off of the master branch to work on stuff and then merge the two back together.There must be a space after the # sign for it to work. For example '# Introduction' will create a large heading. In markdown, pound signs denote headings or titles.md stands for markdown which is a markup language. ReadMe files in Git use the extension.This guide works well with bash but the git commands work in Windows cmd as well.This means you can just do: git config -global merge.tool p4merge P4merge is now supported natively by msysgit. With the settings describe above, MSysGit1.6.3, DOS session or Git bash session: Just tested it (it turns out, you can download and install only p4merge - section Client/Visual Merge Tool -, even if you do not have any other P4 product installed). the need to always have 3 files to merge as parameters (even when 'base' does not exist.).the conditional path for calling the tool, based on the existence of a "base" file.the use of double quotes around $base, $alocal, $remote, $result within the script.the use of " merge" as name of the merge.tool name (since the actual tool is called in the merge.sh script, where you can switch between any number of merge tool you want).the use of PWD in the config of the merge.P4merge.exe -dl "$result" "$alocal" "$remote" "$result" P4merge.exe -dl "$base" "$alocal" "$remote" "$result" # Passing the following parameters to mergetool: (when a file is created in two different branches being then merged, there would be no common ancestor for that file) #!/bin/sh Git config -global "merge.sh \"$PWD/$LOCAL\" \"$PWD/$BASE\" \"$PWD/$REMOTE\" \"$PWD/$MERGED\""Īnd merge.sh being a wrapper (copied in a directory referenced by your PATH environment variable), able to take into account the case where no BASE exists. You will see here my config for DiffMerge or KDiff3.īased on that, I would recommend for p4merge: git config -global merge.tool merge Not sure why but the quoting screwed things up for me. Git config -global 'p4merge $BASE $LOCAL $REMOTE $MERGED' This worked for me using msysGit on windows 7: git config -global merge.tool p4merge
