Hi,
there is one strange situation with directory permissions that I run into every now and then, and now I face it a gain with a webserver.
Situation (example):
drwxrwsr-x 14 user www-data 4096 Jul 28 11:06 .
drwxr-xr-x 2 www-data www-data 4096 Jul 28 11:06 subdir

Hi,
I've created a user named fwadmin, group named fwadmin and made the user belong to that group. I created the user and group using the 'User Manager' in Centos.
The user belongs to /etc/fw.Does this also mean that the group fwadmin belongs to /etc/fw. That is what I want.
But when I... (4 Replies)

What would be a practical way of making sure files I upload to/edit in a particular directory on a server always have the correct group permissions?
I'm forgetful, so I try to automate things like chgrp'ing the files when I'm done. I could write a script to be run by cron. Is that the only way,... (2 Replies)

chmod
CHMOD(1) General Commands Manual CHMOD(1)NAME
chmod - change mode
SYNOPSIS
chmod [ -Rf ] mode file ...
DESCRIPTION
The mode of each named file is changed according to mode, which may be absolute or symbolic. An absolute mode is an octal number con-
structed from the OR of the following modes:
4000 set user ID on execution
2000 set group ID on execution
1000 sticky bit, see chmod(2)
0400 read by owner
0200 write by owner
0100 execute (search in directory) by owner
0070 read, write, execute (search) by group
0007 read, write, execute (search) by others
A symbolic mode has the form:
[who] op permission [op permission] ...
The who part is a combination of the letters u (for user's permissions), g (group) and o (other). The letter a stands for all, or ugo. If
who is omitted, the default is a but the setting of the file creation mask (see umask(2)) is taken into account.
Op can be + to add permission to the file's mode, - to take away permission and = to assign permission absolutely (all other bits will be
reset).
Permission is any combination of the letters r (read), w (write), x (execute), X (set execute only if file is a directory or some other
execute bit is set), s (set owner or group id) and t (save text - sticky). Letters u, g, or o indicate that permission is to be taken from
the current mode. Omitting permission is only useful with = to take away all permissions.
When the -R option is given, chmod recursively descends its directory arguments setting the mode for each file as described above. When
symbolic links are encountered, their mode is not changed and they are not traversed.
If the -f option is given, chmod will not complain if it fails to change the mode on a file.
EXAMPLES
The first example denies write permission to others, the second makes a file executable by all if it is executable by anyone:
chmod o-w file
chmod +X file
Multiple symbolic modes separated by commas may be given. Operations are performed in the order specified. The letter s is only useful
with u or g.
Only the owner of a file (or the super-user) may change its mode.
