Default permissions

Dermot Beirne — Wed, 09 May 2001 10:48:03 GMT

Hi have inherited a system that was not very well taken care of. It is running HPUX 10.20 If something seemed suspect, the first thing tried was chmod 777 on the whole directory, etc! I would like to start by getting the permissions back to normal. Is there somewhere I can get a list of what the default permissions of all the key system directories, e.g. /etc /dev, etc. should be.
Thanks.
Dermot

Hi Dermont,

well I guess at first I think you need to have a reference system, to look up what you want to set.

I would start there with
ls -l | cut -c2- | awk '{ print "chmod " $1 " " $9 }' >file_to_be_edited.sh

In this file_to_be_edited.sh globaly exchange
--x -> 1
-w- -> 2
-wx -> 3
r-- -> 4
r-x -> 5
rw- -> 6
rwx -> 7

and so on ...

Check (!) and execute it, and I guess 85% is done.
Do corresponding if user and group has been changed in addition.

Base your listing on
ls -l `find /etc -print`
if you need to recurse the subdirs (this will take time).

Compare the above output of both systems to find diffrences.

Hope this helps
Volker

All the default permissions for the key system directories and files are in;

/var/adm/sw/products/OS-Core/UX-CORE/INFO

Search this file (INFO) for path and mode commands;

grep -e path -e mode INFO

and it will list paths (files or dirs) and their permissions after each one. If several paths are together before a mode entry then all the files/dirs have the same permissions as the following mode entry. You should be able to write a script to read all this in and apply it.

Hi Dermot:

Andreas Voss wrote an elegant awk script to rectify this very problem. See this thread for his script:
