At first, this looks like something left over from the "-i" parameter supplied to ausearch to interpret the values in the audit records to give you that plaintext. But more likely, it is an alias in ~/.bashrc, ~/.bash-profile, ~/.profile, /etc/bashrc, /etc/bash.bashrc, /etc/profile, /etc/profile.d/* that is nannying you to be sure you meant to delete what you are asking to delete. This can be overridden with -f. rm(1) options preceed the filespec. > Alan - RGB -- Richard Guy Briggs <r...@redhat.com> Sr. S/W Engineer, Kernel Security, Base Operating Systems Remote, Ottawa, Red Hat Canada IRC: rgb, SunRaycer Voice: +1.647.777.2635, Internal: (81) 32635 -- Linux-audit mailing list Linux-audit@redhat.com https://listman.redhat.com/mailman/listinfo/linux-audit
