I keep re-writing the following script for cygwin/bash because I find myself working on proof of concept code, and new environments without source control systems in place.

I am posting it for two reasons: I will need it again and it is easier to remember cygwin/bash from my own examples.

The following script versions all new files in a directory:

#!/usr/bin/bash # The directory we are backing up to backupdir="/cygdrive/c/backup"; # Get the directory that will be backed up dir=$1; # Give user information echo "Versioning files in: $dir"; echo "Current backup in: $backupdir"; # If datestamp.file is not found then # this is a new directory, no changes found if [ ! -f $dir/datestamp.file ] then   echo "Initial backup request";   echo '.' > $dir/datestamp.file; else   datestring=`date +%D-%H-%M | sed 's/\//-/g'`   #echo "datestring: $datestring";   for f in `find $dir -name "*" -newer $dir/datestamp.file`;   do     if [ $f = "." ]; then        echo "Ignoring: $f";     else        #echo "Currently processing: $f";        f2=${f/\./\/$backupdir};        if [ -d $f ]        then          echo "Creating directory: $backupdir/$f2";          mkdir -p $backupdir/$f2;        else          f2=$f-${datestring};          f2=${f2/\\./\/$backupdir};          echo "Versioning file to: $backupdir/$f2";          cp $f $backupdir/$f2;        fi     fi   done fi
