  chmod man page
When a symbolic link is encountered and you have not specified the -h flag, the chmod command changes the mode of the file or directory pointed to by the link and not the mode of the link itself.
This is equivalent to the command sequence: chmod g-w mydir chmod o-w mydir chmod g+x mydir chmod o+x mydir 3.
If the chmod subroutine or fchmod subroutine is unsuccessful, a value of -1 is returned, and the errno global variable is set to identify the error.

 Chmod - Wikipedia, the free encyclopedia
The initial letter is capitalized due to technical restrictions.
In the chmod command you use the combination of 3 numbers, the first number sets the permission for the owner of the file, the second for the group and the last for everybody else.

 chmod
The chmod utility shall change any or all of the file mode bits of the file named by each file operand in the way specified by the mode operand.
Some implementations of chmod never used the process' umask when changing modes; systems conformant with this volume of IEEE Std 1003.1-2001 do so when who is not specified.
chmod() function from the System Interfaces volume of IEEE Std 1003.1-2001 because that specification requires certain side effects upon alternate file access control mechanisms that might not be appropriate, depending on the implementation.

chmod permits you to produce useless modes so long as they are not illegal (for instance, making a text file execut- able).
If you use chmod to change the file group owner permissions on a file with ACL entries, both the file group owner per- missions and the ACL mask are changed to the new permis- sions.

 IRIX: chmod
Absolute changes to permissions are stated using octal numbers: chmod nnn file(s) where n is a number from 0 to 7.
Symbolic changes are stated using mnemonic characters: chmod a operator b file(s) where a is one or more characters corresponding to user, group, or other; where operator is +, -, and =, signifying assignment of permissions; and where b is one or more characters corresponding to type of permission.
Permissions are described in three sequences each having three characters: User Group Other rwx rwx rwx This example (meaning that user, group, and others all have reading, writing, and execution permission to a given file) demonstrates two categories for granting permissions: the access class and the Page 1 chmod(1) chmod(1) permissions themselves.

When using chmod to set or change file permissions, there are two notations that are recognized: Alpha: Use of the + and - operators to change one of the three types of access for each category.
For example: chmod 644 filename Changing the permissions: (we will get to the 'why' after this) Many people that are new to unix will use Alpha representation to change the permission of a file.
There is an option to chmod (-R) that will traverse a directory structure to change the modes of all files and subdirectories in the tree.

 chmod(txt) manual page
the svid2 compliant version of the chmod command ignores the umask value if who is not specified in the symbolic mode of the command (chmod [who] operation permission).
in other words, if you omit who from the chmod command line, the version of the command that is compliant with the svid2 standard behaves exactly as if you specified the character a as the value for who.
the version of the chmod command that is svid2 compliant also supports equivalents in absolute mode for the s permission in symbolic mode.

 HMUG: man chmod (1)
The chmod utility modifies the file mode bits of the listed files as specified by the mode operand.
An absolute mode is an octal number constructed from the sum of one or more of the following values: 4000 (the set-user-ID-on-execution bit) Executable files with this bit set will run with effective uid set to the uid of the file owner.
The chmod utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compat- ible with the exception of the perm symbol ``t'' which is not included in that standard.

 The chmod Command | Linux Journal
Chmod also provides a few command line options to simplify administrative tasks.
The -c option causes chmod to display messages only when files are changed, and the -f option suppresses messages about files that can't be changed.
Chmod also provides a --version option to display the version and --help to see a short help message.

chmod changes the permissions of each given file according to mode, which can be either a symbolic representation of changes to make, or an octal number representing the bit pattern for the new permissions.
chmod 660 filename           for files you want to edit, but not be visible to the world
So, ``chmod 664 filename'' gives the owner of the file read & write (4+2+0) permission, gives the group read & write (4+2+0) permission, and gives the rest of the world read-only (4+0+0) permission.

Chmod is simply a way of editing the permissions to a file - who gets to do what on it.
There are 3 groups of user in chmod, and 3 permission states that can be given to them.
Most FTP clients have it laid out in an easy to use graphical interface, which can be accessed by right clicking on the folder/file you wish to CHMOD, and selecting the appropriate option ("File Attributes", "CHMOD", "File Permissions" and "Properties" are some of the most likley options).

The chmod command allows changing of permissions by names, in a format similar to the way that they are printed on the screen after issuing the 'ls -l' command.

When the -c or -v options are specified, change notifications are written to standard output using the format, mode of %s changed to %0.4o (%s), with arguments of the pathname, the numeric mode, and the resulting permission bits as would be displayed by the ls command.

 What CHMOD? File Permissions Calculator - Classical Webdesigns, complete website design.
Check the Read/Write/Execute boxes to calculate the chmod values and chmod string, or enter the chmod value to retrieve the Read/Write/Execute options.
CHMOD (change mode) is a Unix command that tells the server how much access it can grant to a file (permissions).
So, we use chmod to set the permissions of the file so that anybody can read and execute (run) the database (assuming it's not secret), but only you can write to the database (i.e., update its contents).

The chmod command in UNIX interprets the first number for owner (yourself), second number for group (other users in your group), and the third for others (everyone else).
For example, chmod 666 filename will change file permission to read, write for all three user categories: owner, group and others.
chmod 660 filename only gives read and write access to the owner and group.
