The chmod (short for change mode) command is used tomanage file system access permissions on Unix and Unix-like systems. There arethree basic file system permissions, or modes, to files anddirectories:

• read (r)
• write (w)
• execute (x)

Each mode can be applied to these classes:

• user (u)
• group (g)
• other (o)

The user is the account that owns the file. Thegroup that owns the file may have other accounts on the systemas members. The remaining class, other (sometimes referred toas world), means all other accounts on the system.

You can view the modes on files and directories by executing this command:

ls -l

In the following example, file1 is readable and writable to theuser and readable to everyone on the system. file2 is readable,writable and executable by everyone. file3 is readable, writableand executable only to the user:

Hi everyone I was trying to open a file (a keygen to be more precise).it was non-executable so I used chmod +x command in terminal and everything went. While chmod is useful for changing existing permissions, what sets up the initial and default permissions that the system applies to new files? If you open the OS X Terminal and run the.

To change the permissions of a file, one uses the chmodcommand, with the following syntax:

chmod [references][operator][modes] filename

The references are shorthand (u,g, or o) for each class. Theoperator determines whether to add (+),remove (-) or explicitly set (=) theparticular permissions. The modes are read(r), write (w), or execute(x).

For example, to add the execute permission for the user tofile1:

chmod u+x file1

To remove the write permission for others for file2:

chmod o-w file2

You can combine multiple references and modes to set the desired access allat once. For example, to explicitly make file3 readable andexecutable to everyone:

chmod ugo=rx file3

The all (a) mode is the same as ugo, allowingthe previous command to be expressed as:

chmod a=rx file3

For more information on changing permissions, run this command:

man chmod
