permission

[kacou]

I want to give the permission 'read' on “/var/adm/sulog“ to the user Joe.

[Pete Randall]

So what's your question?

Have you thought of using sudo? The file has the permissions it has for a reason.

You can give read only to everyone with:
chmod a+r /var/adm/sulog

Otherwise you'll need to create an ACL. See setacl(1), aclv(5):

if you want to give permission to the user you can use what is mentioned above.

but alternatively you can apply ACL to that user only on that particular user.

hi,

the owner of /var/adm/sulog is root.and permission is rw for owner.
if you want to read sulog with Joe user,
you can easly add the Joe user to the root group from /etc/group.

[Mustafa Gulercan]

hi,
sorry for missing,
final step you must change permission -rw-rw---- sulog.

mustafa

[kacou]

can you give me the syntaxe, command?

[Jeeshan]

#chmod 550 sulog

[kacou]

syntaxe to add "joe" in the /etc/group

[Pete Randall]

1. vi /etc/group
2. locate the root group line
root::0:root
3. At the end of this line, add "joe"


Pete

[Jeeshan]

the /etc/group folder contains the goup name, not user name.
when you apply command
#groupadd
the groupname has been added in /etc/group file.

[Pete Randall]

From man 4 group:

group contains for each group the following information:

+ group name

+ encrypted password

+ numerical group ID

+ comma-separated list of all users allowed in the group


Pete

[Mustafa Gulercan]

hi,
#chmod 660 /var/adm/sulog
and edit the file /etc/group as following;

vi /etc/group
add the Joe user and of the line,
root::0:root,joe

mustafa

Already mentioned by Mark earlier - why not using "sudo" to view the file???

Dear Kacaou

regarding permission in simple way understand how to give permission

rwx
r is read
w is write
x is execute

x has the value 1
w has the value 2
and read has the value 4
and in which order we have to give
user-group-others
for example
if u are giving chmod 777 then permission of the file will be rwx-rwx-rwx means
read+write+execute(4+2+1) and u are giving these permission to the user, group and others, so everybody will get grant permission
based these calculation u can assign permission in simple way depends on requirement
thanks and regards

>Sajjad: x has the value 1 ...
>based these calculation you can assign permission in simple way

Instead of using stinkin' numbers you can use the symbolic form.
The man page says this about the numeric form: (Obsolescent)

(You only have to know about numbers for the chmod ftp command.)

[Torsten.]

Consoder this:
by adding Joe to the root user group you will grant access for Joe also to many other files.
Do you want to do this?

Again, I would suggest to setup a sudo-command for reading this particular file.
