Top Forums UNIX for Beginners Questions & Answers Printing the user and group info Post 303040557 by apmcd47 on Thursday 31st of October 2019 12:59:09 PM

Code:
mygroup=$(groups $user)
printf "User_name: \"$user\"\nGroup_name: \"%s\"\n" ${mygroup#*:}

You embed the username in the format string in printf. The ${mygroup#*:} strips everything to the left of the ":". Printf will keep repeating until all items in mygroup have been printed.
