UNIX for Dummies Questions & Answers

IMHO there are 2 aspects:
From a unix point of vue any user who has a an access (except chroot stuff) to a box can accees to all directories and files except those very few where "others" have no perms at all(and user is not in <group>...)... Having access doesnt mean the user can do what he wants: This depends on if he is owner or belongs to the group that has privileges...( and depends of the privileges too...)

From a webserver point of vue: it depends all how the server is configured (users can be defined for web services but dont have unix account...)e.g. an apache server will only show (directories...) what you have configured in httpd.conf

Thanks for the reply.

I think i was not clear with 'access' in my previous post. , all I want to know in my script is a way to find if a 'userid' has read/write-permission to a file/dir. Again, 'userid' is not the owner of that file/dir and that 'userid' might be in a group.

thank you.

I haven got the time to write the script for you...
But I will give you some clues:

Code:

ant:/home/vbe $ id
uid=200(vbe) gid=2(bin) groups=20(users),60(oper),104(hpsmc),160(sasdba),200(dba),220(prod),,519(mysql)
ant:/home/vbe $ ls -ld . |awk '{print $3}'
vbe
ant:/home/vbe $ ls -ld . |awk '{print $4}'
bin
ant:/home/vbe $ groups vbe
 bin  dba hpsmc mysql ols oper prod  sasdba  users

You would need a loop to see compare group with user's groups

This thread could give some ideas also
