new file mod's

Aaron Gray · External Since: Jun 01, 2005 Posts: 197

How do I make Cygwin ("GNU/Linux clone", horror of all horrors !) generate
new files with a different set of file attributes as even for text files it
is making them executable, and its pissing me off on using svn diff as it is
marking new files as being executable there too.

Anyway is there a command line chmod but sets the default file creation
attributes ?

Many thanks in advance,

Aaron

Ah umask ! Great but Windows is still WindoZ and is creating text files as
executable. Great nice security feature, I don't say.

Sorry for the noise,

Aaron

And remember that the umask /removes/ permissions rather than setting them.
For instance, a umask of 022 will
- remove the group write permission, if it would otherwise have been set, &
- remove the other write permission, if it would otherwise have been set

You cannot use umask to /set/ permissions.

Generate how? Text editor? Copying? Downloading? What filesystem?

That's something completely b0rken OR you have a configuration error,
as the executable should not be on by default. Initial mode is
normally controlled by the shell involved with the 'umask' command.
For a Bourne style shell like bash:

[compton ~]$ help umask
umask: umask [-S] [mode]
The user file-creation mask is set to MODE. If MODE is omitted, or if
`-S' is supplied, the current value of the mask is printed. The `-S'
option makes the output symbolic; otherwise an octal number is output.
If MODE begins with a digit, it is interpreted as an octal number,
otherwise it is a symbolic mode string like that accepted by chmod(1).
[compton ~]$ umask
022
[compton ~]$

Note that the mask says bits NOT to set, and a '2' turns off the Write
bit. Note also that even with a mask of zero, the eXecute bit is never
set by default.

THE EXCEPTION TO THIS RULE is if you have the filesystem set as one
that doesn't have UNIX permissions - such as FAT and friends. Because
they have no permissions (or ownership, etc.), these attributes are
faked with the 'mount' command used to make the filesystem accessible.
This may show up in /etc/fstab. For that, "man mount"

All very well, useful to know, and good, but that does not help poor old
Windows !

Yep its the text editor + Windows !

Notepad does the same so it is Windows, doing it for bat and cmd but also
..txt files.

Thanks Moe,
