Add usera to a group, change the ownership of those programs to that group and
give execute permissions for that program only to user and group.
# groupadd groupa
# gpasswd -a usera groupa
# chown root:groupa /usr/bin/foo # Where foo is the program you want to
# chmod 754 /usr/bin/foo
7 = read, write and execute (for root), 5 = read, execute (for group members),
4 = read only (for non-group members)
SuSE may have a graphical tool for one or more of the above operations, though
I do not know about that.
"Where shall I begin, please your Majesty ?" he asked.
"Begin at the beginning,", the King said, very gravely,
"and go on till you come to the end: then stop."
