http://www.unix.com – greetings, i have an executable that reads its config from an xml file. this executable needs to be started as the current user. there is a line in the xml file that contains the following: Code: <option name="USER_ID" value="myuserid"/> the current value is an actual user id (mine) as it was populated when i configured the executable with a supplied gui. what i'd like to do is put $USER there instead. is something like this possible? joe.
