Check the permissions of a user
Users enter a user and a path to the directory.
Returns the result is the child folders and files in the folder the user to enter and rights that
that user on the directory.
for example:
suppose we have the Public folder as follows:
If user enter:
-Kenshin
or /home/kenshin/Public
output:
Code:
abc: kenshin: rw
my shell:
Code:
echo "Enter User:" read user grep "$user" /etc/group
but not very feasible, one can help me, help me plzzz, thank very much
What I need to do is: I need to use the grep command to search for pattern in directory and sub-directories. And also I need to show the permission of file been seached by the grep command.
Could any one please suggest me?

Hi,
For a particular set of files, am trying to check if they are writable. i.e., checking whether they are having permissions greater than 755.
Am able to check this using the statement:

mnthome
mnthome(1) BSD General Commands Manual mnthome(1)NAME
mnthome -- mount an AFP (AppleShare) home directory with the correct privileges
SYNOPSIS
mnthome [-v] [-d] [-m mntpath] [-n] [-b] [-p password] [-i] [-x mount point] [-u] [-s]
DESCRIPTION
The mnthome command unmounts the AFP (AppleShare) home directory that was automounted as guest, and remounts it with the correct privileges
by logging into the AFP server using the current username and password. This command also allows you to have guest access turned off on your
AFP server too and still have AFP home directories work with "su".
When you ssh into another computer using an account that has an AFP home directory or you "su <netuser>" where <netuser> is an AFP home
directory user, then the resulting home directory will not have the correct access privileges.
This is because automount is assuming NFS behavior which assumes that all computers share the same user/group privileges and mounts volumes
using "no security" and lets the client enforce privileges based on the current user.
AFP is different since the privileges are based on the user that logged into the server. Since automount does not put up an authentication
dialog asking for an user name and password, automount mounts the fileserver using guest login. Thus you end up with getting the world
access privileges and the privileges are shown via "mapping". You also would have to allow guest access to the server to that sharepoint.
Mapping makes all the files/folders appear like they are owned by the current user. Even those items not really owned by the current user
show up as being owned by the current user. The server provides user access rights (UARights) which is a summary of what the access rights
are regardless of the category (owner, group, world) from which they were obtained. When doing "mapping", the AppleShare client will take
these UARights and show them as the owner rights. So, everything looks like it is owned by the current user and the owner rights are set to
the UARights. Thus if you had access to that file/folder before, then you still do.
The options are:
-v Display version number.
-d Print debugging information.
-m Alternative mount point is specified with the -m option followed by a path to an existing directory. Normally, the volume is mounted
in /Network/Servers/ or /var/automount/Network/Servers/.
-n Do not force the unmount of the previous mount point.
-b Exec the user's shell after mount of home.
-p A password may be specified with the -p option followed by a password. If this option is not used, then the user will be prompted to
enter in a password.
-i Display information about the AFP home mount point.
-u Attempt to unmount the current home directory mount.
-x This option must be followed by a path to an existing AFP mount point. Display information about the mount point.
-s Skip preflight check to see if the currently mounted home directory is already correctly mounted for the user.
EXAMPLES
The following example illustrates how to mount an AFP home directory:
mnthome
This example shows how to print the debugging information and provide a password:
mnthome -d -p foobar
SEE ALSO mount(2), unmount(2), mount(8)mount_afp(8)BUGS
I get the mounting url from the "home_loc" attribute and the mountpath from the "home" attribute (with the path from home_loc subtracted
out). If your AFP home directory automounts in a different location, then you need to use the -m option to specify an alternative mount
point.
I cant figure out how to cd out of the current home dir so I can do the unmount and then restore the user back into the new home dir. If you
are in the AFP home directory when you use mnthome, you automatically get put back into that same directory when mnthome leaves. If mnthome
works, then your current directory is a dead directory and you need to "cd ~" to get to your new home directory.
If the server with the home directory was already mounted by another user, you will not be able to replace it with a mount made by your user
id. The original mount must be first unmounted by the mounting user or root.
HISTORY
The mnthome command first appeared Mac OS X version 10.3.
RETURN VALUES
0 mnthome successfully remounted the AFP home directory.
[EINVAL] Invalid arguements were passed in.
[EPERM] The current AFP home directory could not be unmounted by mnthome because the current user does not have the correct
access. The current AFP home directory was probably mounted by another user first.
[EAUTH] Incorrect password.
