Can I specify multiple users for myself in gitconfig

Question

In my    gitconfig  I list my personal email address under  user   since that s what I want to use for Github repos   But  I ve recently started using git for work  too  My company s git repo allows me to commit  but when it sends out announcements of new changesets  it says they are from Anonymous because it doesn t recognize the email address in my  gitconfig - at least  that s my theory   Is it possible to specify multiple  user  definitions in  gitconfig  Or is there some other way to override the default  gitconfig for a certain directory  In my case  I check out all work code in   worksrc  - is there a way to specify a  gitconfig for only that directory  and its subdirectories

Maybe it is a simple hack  but it is useful  Just generate 2 ssh keys like below   Generating public private rsa key pair  Enter file in which to save the key   Users GowthamSai  ssh id rsa   work Enter passphrase  empty for no passphrase   Enter same passphrase again  Your identification has been saved in damsn  Your public key has been saved in damsn pub  The key fingerprint is  SHA256 CrsKDJWVVek5GTCqmq8 8RnwvAo1G6UOmQFbzddcoAY GowthamSai Gowtham-MacBook-Air local The key s randomart image is   --- RSA 4096 ----      oEo  o            o o o o            o o o o                                         S           o    o                oo                                     o                  ---- SHA256 -----    Same way create one more for personal  So  you have 2 ssh keys  work and company  Copy work pub  work  personal pub  personal to    ssh  Directory    Then create a shell script with the following lines and name it as crev sh  Company Reverse  with the following content    cp    ssh work    ssh id rsa cp    ssh work pub    ssh id rsa pub   Same way  create one more called prev sh  Personal Reverse  with the following content    cp    ssh personal    ssh id rsa cp    ssh personal pub    ssh id rsa pub   in    bashrc add aliases for those scripts like below   alias crev  sh    ssh crev sh  alias prev  sh    ssh prev sh  source    bashrc   Whenever you wanna use company  just do crev  and if you wanna use personal do prev  -p    Add those ssh keys to your GitHub accounts  Make sure  you don t have id rsa generated previously  because those scripts will overwrite id rsa  If you have already generated id rsa  use that for one of the accounts  Copy them as personal and skip the generation of personal keys

git aliases  and sections in git configs  to the rescue   add an alias  from command line    git config --global alias identity    git config user name    git config user  1 name    git config user email    git config user  1 email         then  set  for example  git config --global user github name  your github username  git config --global user github email your github email   and in a new or cloned repo you can run this command   git identity github   This solution isn t automatic  but unsetting user and email in your global    gitconfig and setting user useConfigOnly to true would force git to remind you to set them manually in each new or cloned repo   git config --global --unset user name git config --global --unset user email git config --global user useConfigOnly true

There is a simple solution that seems to work well for avoiding mistakes   Simply remove the  user  section from your    gitconfig  which will prevent you from making any commits without setting user name for each repository   In your    bashrc  add some simple aliases for the user and email   alias ggmail  git config user name  My Name  git config user email me gmail com  alias gwork  git config user name  My Name  git config user email me work job

Another option to get git to work with multiple names   emails is by aliasing git and using the -c flag to override the global and repository-specific config   For example  by defining an alias   alias git   usr bin git -c user name  Your name  -c user email  name example com     To see whether it works  simply type git config user email     git config user email name example com   Instead of an alias  you could also put a custom git executable within your  PATH      bin sh  usr bin git -c user name  Your name  -c user email  name example com         An advantage of these method over a repository-specific  git config is that it applies to every git repository when the custom git program is active  In this way  you can easily switch between users names without modifying any  shared  configuration

This answer is partially inspired by the post by  Saucier  but I was looking for an automated way to set user name and user email on a per repo basis  based on the remote  that was a little more light weight than the git-passport package that he developed   Also h t to  John for the useConfigOnly setting   Here is my solution    gitconfig changes    github      name    lt github username gt      email    lt github email gt   gitlab      name    lt gitlab username gt      email    lt gitlab email gt   init      templatedir      git-templates  user      useConfigOnly   true   post-checkout hook which should be saved to the following path     git-templates hooks post-checkout      usr bin env bash    make regex matching below case insensitive shopt -s nocasematch    values in the services array should have a corresponding section in    gitconfig where the  name  and  email  for that service are specified remote url     git config --get --local remote origin url    services        github       gitlab     set local user config         local service    1       local config    2       local service config     git config --get   service    config         local local config     git config --get --local user   config          if       local config         service config       then         git config --local  user   config      service config           echo  repo  user   config   has been set to    service config        fi      if remote url doesn t contain the any of the values in the services   array the user name and email will remain unset and the   user useConfigOnly   true setting in  gitconfig will prompt for those   credentials and prevent commits until they are defined for s in    services       do     if       remote url         s       then         set local user config    s    name          set local user config    s    email          break     fi done   I use different credentials for github and gitlab  but those references in the code above could be replaced or augmented with any service that you use   In order to have the post-checkout hook automatically set the user name and email locally for a repo after a checkout make sure the service name appears in the remote url  add it to the services array in the post-checkout script and create a section for it in your  gitconfig that contains your user name and email for that service     If none of the service names appear in the remote url or the repo doesn t have a remote the user name and email will not be set locally   In these cases the user useConfigOnly setting will be in play which will not allow you to make commits until the user name and email are set at the repo level  and will prompt the user to configure that information

If you do not want to have a default email address  email address links to a github user   you can configure that you want to be asked  How you can do that depends on the version of git you use  see below   The  intended  drawback is that you have to configure your email address  and your name  once for every repository  So  you cannot forget to do it   Version  lt  2 7 0   user      name   Your name     email     none     in your global configuration    gitconfig as stated in a comment by Dan Aloni in Orr Sella s blog post  When trying to do the first commit in a repository  git fails with the nice message       Please tell me who you are   Run    git config --global user email  you example com    git config --global user name  Your Name   to set your account s default identity  Omit --global to set the identity only in this repository   fatal  unable to auto-detect email address  got   none      The name is taken from the global config when the email address is set locally  the message is not perfectly accurate    2 7 0   Version  lt  2 8 0  The behaviour in versions  lt  2 7 0 was not intended and fixed with 2 7 0  You can still use a pre-commit hook as described in Orr Sella s blog post  This solution works also for other versions  but the other solutions not for this version   Version   2 8 0  Dan Aloni added an option to achieve that behaviour  see release notes   Use it with    user      useConfigOnly   true   To make it work you may not give a name or email address in the global config  Then  at the first commit  you get an error message  fatal  user useConfigOnly set but no name given   So the message is not very instructive  but since you set the option explicitly  you should know what to do  In contrast to the solution of versions  lt  2 7 0  you always have to set both name and email manually

With conditional includes in Git 2 13  it is now possible to have multiple user email coexist on one machine with little work   user gitconfig has my personal name and email  work-user gitconfig has my work name and email  Both files are at   path   So my personal name email applies by default  For c  work  dir  my work name email is applied  For c  work github  dir  my personal name email is applied  This works as the last setting gets applied        gitconfig  include      path   user gitconfig  includeIf  gitdir i c  work        path   work-user gitconfig  includeIf  gitdir i c  work github        path   user gitconfig   gitdir is case-sensitive and gitdir i is case-insensitive    gitdir i github   would apply the conditional include for any directory with github in its path

After getting some inspiration from Orr Sella s blog post I wrote a pre-commit hook  resides in    git templates hooks  which would set specific usernames and e-mail addresses based on the information inside a local repositorie s    git config   You have to place the path to the template directory into your    gitconfig    init      templatedir      git templates   Then each git init or git clone will pick up that hook and will apply the user data during the next git commit  If you want to apply the hook to already exisiting repos then just run a git init inside the repo in order to reinitialize it   Here is the hook I came up with  it still needs some polishing - suggestions are welcome   Save it either as      git templates hooks pre commit   or     git templates hooks post-checkout   and make sure it is executable  chmod  x   post-checkout    chmod  x   pre commit     usr bin env bash    -------- USER CONFIG   Patterns to match a repo s  remote origin url  - beginning portion of the hostname git remotes 0   Github  git remotes 1   Gitlab     Adjust names and e-mail addresses local id 0 0   my name 0  local id 0 1   my email 0   local id 1 0   my name 1  local id 1 1   my email 1   local fallback id 0     local id 0 0    local fallback id 1     local id 0 1        -------- FUNCTIONS setIdentity         local current id local id      current id 0     git config --get --local user name       current id 1     git config --get --local user email        local id             if       current id 0          local id 0     amp  amp               current id 1          local id 1        then         printf   Local identity is  n          printf      User   s n    Mail   s n n     current id          else         printf      User   s n    Mail   s n n     local id              git config --local user name    local id 0            git config --local user email    local id 1        fi      return 0      -------- IMPLEMENTATION current remote url    git config --get --local remote origin url    if      current remote url      then      for service in    git remotes       do            Disable case sensitivity for regex matching         shopt -s nocasematch          if      current remote url      service     then             case   service  in                     git remotes 0                          printf   n     An Intermission n     s repository found      git remotes 0                        setIdentity    local id 0                          exit 0                                            git remotes 1                          printf   n     An Intermission n     s repository found      git remotes 1                        setIdentity    local id 1                          exit 0                                                                 printf   n    pre-commit hook  unknown error n   Quitting  n                      exit 1                                     esac         fi     done else     printf   n     An Intermission n    No remote repository set  Using local fallback identity  n      printf      User   s n    Mail   s n n     local fallback id             Get the user s attention for a second     sleep 1      git config --local user name    local fallback id 0        git config --local user email    local fallback id 1    fi  exit 0     EDIT   So I rewrote the hook as a hook and command in Python  Additionally it s possible to call the script as a Git command  git passport   too  Also it s possible to define an arbitrary number of IDs inside a configfile     gitpassport  which are selectable on a prompt  You can find the project at github com  git-passport - A Git command and hook written in Python to manage multiple Git accounts   user identities
