When you want to install a package which needs its own, unpriviledged, user, you can always do it from the System Preferences. But what if you want to use the command-line?

I'm not sure from where this script originated, but I reproduce it here because it's been useful to me.

#!/bin/sh echo "Enter username:" read newuser echo "Enter the full name for user $newuser's:" read long_name echo "Will $newuser an Admin user (y/N)?" read is_admin new_uid=`nidump passwd . | awk -F: '{print $3f}' | sort -n|tail -1` new_uid=`expr $new_uid + 1` nicl . -create /users/$newuser nicl . -create /users/$newuser uid $new_uid nicl . -create /users/$newuser realname "$long_name" nicl . -create /users/$newuser passwd "" nicl . -create /users/$newuser gid 20 nicl . -create /users/$newuser shell "/bin/tcsh" nicl . -create /users/$newuser home "/Users/$newuser" nicl . -create /users/$newuser _writers_passwd $newuser passwd $newuser ditto /System/Library/UserTemplate/English.lproj /Users/$newuser chown -R $newuser:staff /Users/$newuser nicl . -read /users/$newuser if [ "$is_admin" = Y -o "$is_admin" = y ] then nicl . -append /groups/wheel users $newuser nicl . -append /groups/admin users $newuser nicl . -read /groups/wheel nicl . -read /groups/admin fi

I saved this as ~/bin/addu and then did
