Are not valid commands, the last field will be ignored. It is equivalent to:
It does not set permissions for a folder, but rather determines with what permissions new files and directories will be created by the user that uses that umask.
What does
produce? Does the folder exist? What does not work exactly?

Hi, I'm new to unix -solaris.
I've just upgraded a third party software product and am testing
it to see if new files created in a test database directory were being created properly and they aren't. They're owned by the user that created the file, instead of poppa and the group of their files... (2 Replies)
In our file system, the SGID for a directory is set right now. Any new files created in this directory will automatically be assigned the same group from the parent directory.
Is there a way to inherit the file permission from the parent directory as well? The OS is Solaris 2.8.

i've set the permissions to 700 on dir3, dir2, and dir1 to prevent them from... (3 Replies)

Hi.

umask
UMASK(2) Linux Programmer's Manual UMASK(2)NAME
umask - set file mode creation mask
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
mode_t umask(mode_t mask);
DESCRIPTION
umask() sets the calling process's file mode creation mask (umask) to mask & 0777 (i.e., only the file permission bits of mask are used),
and returns the previous value of the mask.
The umask is used by open(2), mkdir(2), and other system calls that create files to modify the permissions placed on newly created files or
directories. Specifically, permissions in the umask are turned off from the mode argument to open(2) and mkdir(2).
The constants that should be used to specify mask are described under stat(2).
The typical default value for the process umask is S_IWGRP | S_IWOTH (octal 022). In the usual case where the mode argument to open(2) is
specified as:
S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP | S_IROTH | S_IWOTH
(octal 0666) when creating a new file, the permissions on the resulting file will be:
S_IRUSR | S_IWUSR | S_IRGRP | S_IROTH
(because 0666 & ~022 = 0644; i.e., rw-r--r--).
RETURN VALUE
This system call always succeeds and the previous value of the mask is returned.
CONFORMING TO
SVr4, 4.3BSD, POSIX.1-2001.
NOTES
A child process created via fork(2) inherits its parent's umask. The umask is left unchanged by execve(2).
The umask setting also affects the permissions assigned to POSIX IPC objects (mq_open(3), sem_open(3), shm_open(3)), FIFOs (mkfifo(3)), and
UNIX domain sockets (unix(7)) created by the process. The umask does not affect the permissions assigned to System V IPC objects created
by the process (using msgget(2), semget(2), shmget(2)).
