[X-Unix] Urgent question about accidentally deleted files

[Aaron]

In the course of testing a shell script, I accidentally deleted all of the following files from my home directory:

.CFUserTextEncoding
.DS_Store
.Xauthority
.bash_history
.cshrc
.eno
.fonts.cache-1
.gdb_history
.gtk-bookmarks
.lesshst
.login
.prismPrefs
.profile
.rnd
.tcshrc
.viminfo

1) Which of these files can I totally ignore without losing anything? (I don't use bash or gdb. I do use tcsh. But if I need to run a bash script, will there be any problems.)

2) Which ones can be replaced using earlier versions? I'm presuming that .tcshrc and .login can, even if the earlier versions are from my Tiger startup. (I'm using Leopard now.)

3) Any other considerations? (Don't tell me about backing up. I'm getting set up to use time machine, but i don't even know if that would let me only recover specific files without replacing other new files.)

 - TIA
