gistfile1.sh

# you'll need to adjust the names of the source and destination ruby versions
# you may also need to adjust the number of fields that are cut (the -f 7 flag in the cut command) if the output of "rvm gemset list" changes at some point down the road

rvm gemset list | sed 's/^[[:space:]]*//' | cut -d ' ' -f 7 | while read gemset; do rvm gemset copy 1.9.2@$gemset 1.9.3@$gemset; done
