Hi

#chmod g+s test

[Bharat Katkar]

Hi,
By the way, "S" is not a sticky, sticky bit is repesented by "t" in the permissions field of a file.

Hi

"t" comes only if file is linked

[Thierry Poels_1]

correct,

S in first rwS is SETUID, small "s" if execute permission is not granted
S in second rwS is SETGID, small "s" if execute permission is not granted
t in last rwt is sticky bit

regards,
Thierry.

You can know sticky bit informations there in chmod man page.

4000 (= u=s) Set user ID on file execution (file only)
2000 (= g=s) Set group ID on file execution (file only)
1000 (= u=t) Set sticky bit

To change to stikcy bit use as,

chmod 1775 test

We are using sticky bit so that,

specific file can be renamed / deleted by that owner there.

Muthu.

Slight correction to Theirry's statements... S and T are displayed if the corresponding execute bit isn't set. s and t display if the corresponding execute bit is set.

aaaaargghh,

I stand corrected. It seems I mixed things up :(

rw- + chmod u+s = rwS
rwx + chmod u+s = rws

sorry

can someone assign negative points to me ;-)
