![]() ![]() How to add only certain files to the staging area in Git If you want to add all files in your project to the staging area, you can use a wildcard. How to add all files in the staging area in Git Just replace filename_here with the name of the file you want to add to the staging area. The command below will add a file to the staging area. ![]() How to add a file to the staging area in Git: You can do so with the command below: git init The first step is to initialize a new Git repo locally in your project root. Just use this command: git config -global credential.helper cacheĮverything starts from here. You can store login credentials in the cache so you don't have to type them in each time. git config -global user.email to cache your login credentials in Git: This command lets you setup the user email address you'll use in your commits. With the command below you can configure your user name: git config -global user.name "Fabio" The command below returns a list of information about your git configuration including user name and email: git config -l So I have written them down and thought it'd be nice to share them with the community. And I've found that these fifty are the ones I use the most often (and are therefore the most helpful to remember). Git has many different commands you can use. This way, different members of the team can copy it locally and everyone has a clear overview of all changes made by the whole team. Then, thanks to an external server like BitBucket, GitHub or GitLab, they can safely store the repository in a single place. ![]() Everyone on the team can keep a full backup of the repositories they're working on on their local machine. This change history lives on your local machine and lets you revert to a previous version of your project with ease in case something goes wrong. What is a Distributed Version Control System?Ī distributed version control system is a system that helps you keep track of changes you've made to files in your project. Linus Torvalds, the developer of the Linux kernel, created Git in 2005 to help control the Linux kernel's development. Git submodule foreach -recursive -quiet 'RESULT=$(git describe -broken -dirty -all)Įcho "- but at least one submodule is dirty.Git is a distributed version control system that helps developers collaborate on projects of any scale. # Bail out now, in case it is not safe to look for sub-modulesĮcho "Main repository is dirty - not checking any submodules." RESULT=$(git describe -broken -dirty -all) This requires a modern (version >= 3.x) of bash as I understand it, it also does not investigate untracked files - which is not unreasonable in my opinion (at least they shouldn't be clobbered if a difference branch is checked out!) - note that it only returns a zero exit status if everything is clean: #!/bin/bash How about using git describe -broken -dirty -all and checking the result to see if it ends in -dirty (or -broken) then, using the same thing on any submodules with git submodule foreach. If untracked files in the working directory are relevant, git status -porcelain is probably the best bet. Using this, we can check for unstaged changes with: git diff -exit-codeĪnd staged, but not committed changes with: git diff -cached -exit-codeĪlthough git diff can report on untracked files in submodules via appropriate arguments to -ignore-submodules, unfortunately it seems that there is no way to have it report on untracked files in the actual working directory. It's also worth noting that, although git status does not give meaningful exit code when the working directory is unclean, git diff provides the -exit-code option, which makes it behave similar to the diff utility, that is, exiting with status 1 when there were differences and 0 when none were found. To make this more robust against conditions which actually cause git status to fail without output to stdout, we can refine the check to: if output=$(git status -porcelain) & then # Working directory clean excluding untracked files If we do not care about untracked files in the working directory, we can use the -untracked-files=no option to disregard those: if then We can use empty output of git status -porcelain as an indicator that there are no changes to be committed: if then It does, however, provide the -porcelain option, which causes the output of git status -porcelain to be formatted in an easy-to-parse format for scripts, and will remain stable across Git versions and regardless of user configuration. UVVs comment is on the right track, but unfortunately the return code of git status doesn't change when there are uncommitted changes. ![]() There's no guarantee that the output will remain the same in future versions of Git or in differently configured environments. Parsing the output of git status is a bad idea because the output is intended to be human readable, not machine-readable. ![]()
