+#+title: How to Clone All Repositories from a GitHub or Sourcehut Account
+#+date: 2021-03-19
+#+description: Learn how to clone all GitHub or Sourcehut repositories.
+#+filetags: :dev:
+
+* Cloning from GitHub
+If you're like me and use a lot of different devices (and sometimes
+decide to just wipe your device and start with a new OS), you probably
+know the pain of cloning all your old code repositories down to your
+local file system.
+
+If you're using GitHub, you can easily clone all of your code back down
+in just seconds. First, create a bash script. I do so by opening a new
+file in =nano=, but you can use =gedit=, =vim=, or something else:
+
+#+begin_src sh
+nano clone_github_repos.sh
+#+end_src
+
+Next, paste in the following information. Note that you can replace the
+word =users= in the first line with =orgs= and type an organization's
+name instead of a user's name.
+
+#+begin_src sh
+CNTX=users; NAME=YOUR-USERNAME; PAGE=1
+curl "https://api.github.com/$CNTX/$NAME/repos?page=$PAGE&per_page=100" |
+  grep -e 'git_url*' |
+  cut -d \" -f 4 |
+  xargs -L1 git clone
+#+end_src
+
+Finally, save the bash script and make it executable.
+
+#+begin_src sh
+chmod a+x clone_github_repos.sh
+#+end_src
+
+Now you can run the script and should see the cloning process begin.
+
+#+begin_src sh
+./clone_github_repos.sh
+#+end_src
+
+* Cloning from Sourcehut
+I haven't fully figured out how to directly incorporate Sourcehut's
+GraphQL API into a bash script yet, so this one will take two steps.
+
+First, log-in to Sourcehut and go to their
+[[https://git.sr.ht/graphql][GraphQL playground for Git]]. Next, paste
+the following query into the left box:
+
+#+begin_src sh
+query {
+  me {
+    canonicalName
+    repositories() {
+      cursor
+      results {
+        name
+      }
+    }
+  }
+}
+#+end_src
+
+The output on the right side will give you an object of all your
+repositories. Just grab that text and remove all the characters such as
+quotation marks and curly brackets. You will need a single-line list of
+space-separated values for the next step.
+
+Now let's create the bash script:
+
+#+begin_src sh
+nano clone_sourcehut_repos.sh
+#+end_src
+
+Next, paste the following bash script in with the list of repositories
+you obtained above and replace =your-username= with your username.
+
+Note that this uses the SSH-based Git cloning method
+(e.g. =git@git...=), so you'll need to ensure you have set up Sourcehut
+with your SSH key.
+
+#+begin_src sh
+repos=(repo1 repo2 repo3)
+
+# List all sub-directories in the current directory
+for repo in "${repos[@]}"
+do
+    # Clone
+    git clone git@git.sr.ht:~your-username/$repo
+done
+#+end_src
+
+Finally, save the bash script and make it executable.
+
+#+begin_src sh
+chmod a+x clone_sourcehut_repos.sh
+#+end_src
+
+Now you can run the script and should see the cloning process begin.
+
+#+begin_src sh
+./clone_sourcehut_repos.sh
+#+end_src
+
+* Moving Repositories to a New Host
+Now that you have all of your code repositories cloned to your local
+computer, you may want to change the remote host (e.g., moving from
+GitHub to GitLab). To do this, let's create another bash script:
+
+#+begin_src sh
+nano change_remote_urls.sh
+#+end_src
+
+Past the following information and be sure to change the URL information
+to whichever host you are moving to. For this example, I am looping
+through all of my cloned GitHub directories and changing them to
+Sourcehut (e.g. =<YOUR_NEW_REMOTE_URL>= -> =git@git.sr.ht:~myusername=).
+
+#+begin_src sh
+# List all sub-directories in the current directory
+for dir in */
+do
+    # Remove the trailing "/"
+    dir=${dir%*/}
+    # Enter sub-directory
+    cd $dir
+    # Change remote Git URL
+    git remote set-url origin <YOUR_NEW_REMOTE_URL>/"${dir##*/}"
+    # Push code to new remote
+    git push
+    # Go back to main directory
+    cd ..
+done
+#+end_src
+
+Finally, save the bash script and make it executable.
+
+#+begin_src sh
+chmod a+x change_remote_urls.sh
+#+end_src
+
+Now you can run the script and should see the cloning process begin.
+
+#+begin_src sh
+./change_remote_urls.sh
+#+end_src
