Perform batch "pull -u" on multiple Mercurial repositories from the parent directory

hg_batch_pull.sh

#!/bin/bash

# This script finds all the mercurial repositories in the current directory
# and does a "hg pull -u" to get the latest changes from all the repositories.
#
# Make sure you know what you're doing before running this ;-)

confirm_prompt() {
   read -p "Are you sure you want to 'hg pull -u' every repository? " -n 1
   echo
   if [[ ! $REPLY =~ ^[Yy]$ ]]; then
      exit 1
   fi
}

confirm_prompt

targetDir=`pwd`
dirObjs=`ls $targetDir`

# check the current directory for mercurial repositories
for d in $dirObjs
do
  if [ -d $d ] && [ -f "$d/.hg/hgrc" ]; then
    echo "--------"
    echo "Updating mercurial repository in $d"
    cd $d
    hg pull -u
    cd ..
  fi
done

Heh, already used it when I didn't intend to. Added a confirm prompt to hopefully stop that from happening ;-)

Added "-------" before each pull is performed, makes it easier to read the status of each pull. Some pulls may require merges afterwards, this makes it easier to read which ones have stuff todo.

Cool, this should come in handy!

This is a handy script, just one suggestion though, if you can add hg update and merge for +1 heads, that will be great.

Here is a windows version for that.
