shell script to pass values properties file in java
I have a properties file that looks like this:
mysql.username=USERNAME
mysql.pass=PASS
I need to change USERNAME and PASS with variable values passed to shell script. I cannot use sed since that will work fine the first time to replace USERNAME and PASS with "values" but once they are replaced, sed will not find the variable names in the file the second time the script runs and thus an issue.
How can this be handled?
shell-script bash

You can obtain old parameters from the properties file before using sed, e.g.
# get old parameters
$ export oldUsername=$(grep mysql.username $FILE | cut -d'=' -f2)
$ export oldPass=$(grep mysql.pass $FILE | cut -d'=' -f2)
# set new parameters
$ export newUsername=NEW_USERNAME
$ export newPass=NEW_PASS
# change parameters
$ sed -i "s/$oldUsername/$newUsername/g" $FILE
$ sed -i "s/$oldPass/$newPass/g" $FILE

It would be nice if you could break down each section of the command. This would help people less experienced in bash and possibly help them fix similar problems in the future based on what they learn here.
