Have a quick question. Please seecompare the line belowfollowing two lines:

ls -al -rws---r-x 1 root root 21872 2009-10-13 21:06 prg1

and, compared it to this

  -rwx---r-x 1 root root 21872 2009-10-13 21:06 prg2

That first line implies that anyone could getDoes the elevated rights and do asetuid bit on Sudo prg1 means, along with the read and execute bits for 'other' mean that an arbitraryany user could get the same program execution rights as thecan run it with root on prg1privileges? The prg2 also has read and execute for 'other', but does not prg2 ? I mean withhave the s "flag"setuid bit set on the first program.

Sorry if not explained properly, so does that mean it can still be run by any user but am new to the Unix environment.without root privileges?

Have a quick question. Please see the line below

Does the setuid bit on prg1, along with the read and execute bits for 'other' mean that any user can run it with root privileges? The prg2 also has read and execute for 'other', but does not have the setuid bit set, so does that mean it can still be run by any user but without root privileges?

Corrected grammar.
