Pull Multiple Repositories

As the ELISSA packages consist of multiple repositories, it would be helpfull to pull all repositories at once before starting working on the source code. This tutorial presents a possible way of doing this.

Install a Credential and Password Manager

To avoid a credential check for evrey repository a credential manager would be usefull. A installation guide for the git-credential-manager is given here. Furthermore a password manager like pass must be installed. Use for pass the following command:

sudo apt-get install pass

When the manager is installed a key for GnuPG must be generated. Use this command:

gpg --gen-key

You will need to provide a name and a e-mail adress as well as a password. When finished, the key selected to be used during git operations:

git config --global credential.credentialStore gpg

Furthermore the password manager pass must be initialized. Use the following command and tabstop to complete the user id:

pass init

Use the Terminal Command

A terminal command is used to go through all subdirectories and executing a git pull command if a \.git folder exists there. The command is taken from this stakoverflow page:

for i in */.git; do ( echo $i; cd $i/..; git pull; ); done

To execute the command, run it in the ~/catkin_ws/src/ folder.

Save the Command

To execute the command more easily, it can be saved in a .sh file in the ~/catkin_ws/src/ folder. To easily run it, it must be executable:

chmod +x filename.sh

It can be executed as shown:

./filename.sh

If you want to use a different command to start it, you can add an alias:

gedit ~/.bashrc

Add this at the end of the file:

alias <new name>='/home/<full path to script>/filename.sh'
