=======================

i'm not talking about deleting any files, just deleting duplicate *.exe 
commands from my command hash, so they don't auto-complete when i press 
<TAB>. the *.exe commands would be there (and be available if called), i 
just wouldn't have to look at them when i tab-complete.

ls -ilh `which cat cat.exe`

that tells me that the two commands are hard-linked; they share the same 
inode. it seems the same way for all of the commands that appear in my 
PATH with and without a ".exe" suffix.

so the question remains: is it "safe" to delete all *.exe files from my 
command hash? or should i first check for the same command, in the same 
place, without the ".exe" suffix?
