Change the timestamps of all files managed in a mercurial repository to the last modified time recorded in the repository. This is useful, for example, when multiple people are using the same Makefile to run a data workflow

sync_hg_mod_times.sh

#!/bin/bash

cd $(hg root)

for f in $(hg st -A | awk '{if($1!="I") print $2}'); do 
  
  # http://stackoverflow.com/a/4039466/564709
  t=$(hg log -l1 --template '{date|isodate}' $f | awk '{d=$1; gsub(/-/,"",d); t=$2; sub(/:/,"",t); printf("%s%s", d, t)}')

  touch -t $t $f
done
