Finds all Mercurial Branches that have Multiple Heads in a given repo.

branchfind.sh

#!/bin/bash

# This simple script will look at all named branches in a given repository
# and print out any branch that contains multiple open heads. This is useful
# to see if your repository is clean or if someone has pushed multiple
# anonymous branches.

foundone=""

# Retrieve the branch list. The format will contain other garbage, so only
# grab the name of the branch using gawk. You could use awk if required.
#branchlist=`hg branches | awk '{print $1}'`
branchlist=`hg branches | gawk '{print $1}'`

# Iterate through the branches and find the one(s) that contain multiple heads.
for branch in ${branchlist[@]}
do
  count=`hg log -r "head() and not closed() and branch('$branch')" --template "{node}\n" | wc -l`
  if [ "$count" != "1" ] ; then
    echo -e "\n ====[ $branch ]====\n"
    hg log -r "head() and not closed() and branch('$branch')"
    echo -e "========================================\n"
    foundone="yes"

done

# If no branches contained multiple heads, state that life is good!
if [ -z "$foundone" ] ; then

Line #19 should contain numeric comparation

  if [ "$count" -ne "1" ] ; then

Use [[ and it doesn't matter ;-)
