Hi Robert, Just rolling dice, but is it possible that the append only attribute is set on the files in question?
For instance, I have the attribute set on a file named *testing* (the append attribute is shown by the 'a' flag): # lsattr testing -----a---------- testing When I try to remove *testing* with the append flag set: # rm testing rm: remove regular empty file ‘testing’? y rm: cannot remove ‘testing’: Operation not permitted If that flag is set on your problematic files, the unsetting the flag will allow you to delete them: # chattr -a testing # rm testing rm: remove regular empty file ‘testing’? y BTW - You have to use lsattr to see the append flag; a normal ls will not show it...
