Bash script: how does the $ wildcard work in git script?
I checked that the following is true, but I still don't understand why or how it works:
git checkout production.release.4.2
production_branch=`git branch | grep "production"`
# May not give the expected result:
# the character $ is being treated as a wildcard and will be expanded, so that the output may include all files in the directory:
# Using double quotes solve the problem:
