From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

that's why root owns my .bash* stuff
I don't think that actually works; the attacker could just remove .bashrc and create a new file with the same name.
If the .bashrc is immutable, the attacker can't remove it.
That's how it works.
The home directory would need to be immutable, not bashrc.
?
It's .bashrc, not bashrc, and .bashrc is in the home directory.
If .bashrc is immutable, it can't be removed from home.
It's the directory that needs to be writable to delete files, not the file itself.
Although the immutable bit (if that's what you're talking about - I thought you meant unsetting the write bit) might change that, I'm not sure.
you're right. that's something i wanted to look into. guess setfacl would do the trick?
"chattr +i" is what I use to make things immutable
thanks
I made a small mistake in my last post It is "chattr +i" to make immutable and "chattr -i" to remove immutability.
