The EASY way? "( source /etc/*-release; echo $PRETTY_NAME )". 'source' executes the commands in the file(s) which, in this case, are simple variable assignments. 'echo' prints the contents of one of those variables. Finally "( ... ; ... )" executes the two commands one after the other in a subshell. When the subshell exits (after the echo command), the variables will be forgotten. > > -- > Regards, > Alf Stockton > > -- For more information, please reread.
