update-repos

Small bash script to quickly update repositories in a root folder. You can specify from which remotes content needs to be fetched, which branches need to be included, and which repositories need to be updated by using a regular expression (case insensitive).

Dependencies

git: https://git-scm.com/

How to use

update-repos.sh <folder> <remote> <branches> <ff-only> <regex>

<folder>: The root folder
<remote>: The git remote you want to update
<branches>: A comma separated list of branches you want to update.
<ff-only>: true or false specifying whether to merge using fast-forward only strategy or not.
<regex>: A regular expression used to filter the repositories that should be updated, based on their name (i.e. the .git part of the clone url).

Examples

Update all master and develop branches using the origin remote in all repositories contained in a folder "my-repos" using only the fast forward merge strategy:
```
update-repos.sh my-repos origin master,develop true
```
Update all master branches in all repositories matched 'notes' contained in a folder "my-repos" while allowing non fast foward merges:
```
update-repos.sh my-repos origin master false notes
```

In the pipeline

Support for parallel processing
Improved command line experience with flags etc
Support for multiple origins (only content fetching, not merging...?)
Investigate partial, shallow fetching,...
Cross platform support
Remove unnecessary usages of grep and sed by parameter substitution etc.
Improve error handling
Rewrite the git remote url validation since it's not required for a git repository folder to end in .git
