Run hg pull over all subdirectories

Question

How can I update multiple mercurial (hg) repositories from their shared parent's directory?

/plugins/search
/plugins/overview
/plugins/chart

I want to change a branch to default one and update them all at once

cd /plugins/search
hg update -C default
hg pull -u

Answer 1

Run the following from the parent directory, plugins in this case:

find . -type d -maxdepth 1 -exec hg update -C default -R {} \;
find . -type d -maxdepth 1 -exec hg pull -u -R {} \;

To clarify:

• find . searches the current directory
• -type d to find directories, not files
• -maxdepth 1 for a maximum depth of one sub-directory
• -exec {} \; runs a custom command for every find
• hg update -C default -R {} hg changes branch to default in each repository
• hg pull -u -R {} hg updates to new branch head if changesets were pulled in each repository

Finding repositories deeper in the directory tree

find . -type d -iname .hg -exec echo \; -exec hg pull -u -R {}/.. \;

The initial -exec echo \; is only there to keep the output clean.

Run this command on your root directory of project which is plugin

find . -maxdepth 1 -type d -print -execdir git --git-dir={}/.git --work-tree=$PWD/{} pull origin develop;
