Raakh · 04-04-2009, 11:43 AM

Hello,

Presently my permissions are:
-bash-3.1$ ls -l /usr/lib/oracle/xe/app/oracle/product/10.2.0/server
/bin/oracle-rwxr-x--- 1 oracle dba 74016852 Feb 19 2006 /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/oracle

but I want to set permissions like this:
-rwsr-s--x 1 oracle dba 74016852 Feb 19 2006 /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/oracle

Kindly help

Thanks & best regards

For an explanation please see: http://www.zzee.com/solutions/chmod-help.shtml

Code:

chmod 6751 /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/oracle

for better understanding
read - 4
write - 2
execute - 1

sticky bit - 1
SUID - 2
SGID - 4

x | xxx | xxx | xxx
rwx rwx rwx
| | |
owner group others

1st bit stands for sticky bit, suid, sgid

so as u needed

-rwsr-s--x, it'l be

- | rwxS | r-xS | --x

6 7 5 1

SUID & SGID = 2+4=6
owner->rwx = 4+2+1=7
group->r-x = 4+1=5
others->--x = 1=1

so it becomes as " chmod 6751 /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/oracle "
