setting security bits on UNIX

setting security bits on UNIX

[Ned]

Hi all,

I don't know how to take off protection from one of my files
Tried umask 022, umask 0, etc, nothing works. The chmod command didn't work either. I don't know the values that I need to put in.
The ls -l fileName command should give me:
-rwxr-xr-x
but not all dashes as it does now.
It's an html file that needs to be read and executed by anybody.
Please help.

Many thanks in advance!
Ned

For even more information, do a "man chmod" for all the gorry details on
file permissions.  Since you're dealing with a text file, you should
probably not need the execute permission on the file so then chmod 644
would be plenty adequate.  Note that chmod 644 would yield
- -rW-r--r--...

Umask determines a default permission given to eny newly created files
under your current user account.

Umask is only for setting the default security settings for that user.

Re: setting security bits on UNIX

[Joseph C. Lininger]

Ned,
Wehn calculating the number you should pass to chmod, the following information is useful. read
is worth 4, write is worth 2, and execute is worth 1. Adding these gives you a single octal
number which represents the permition. Three of these numbers are used to represent user,
group, and world permitions. Thus rwxr-xr-x would be 755.

The umask command represents the permitions to remove from newly created files. You start with
666 for files and 777 for directories. Most systems use a umask of 022, which results in 644
for files and 755 for directories.

Equal causes can produce very unequal effects.

I'm not sure why chmod won't work unless you are not the owner of the
file.  Try:

chmod 755 filename.html

where filename.html is the file you want to make available.  Umask is
used to set the default file permissions, not to change the
permissions on the fly.  See the man pages for chmod, umask, and bash
for more info.  HTH, and have a _great_ day.
