Unfortunately, this nice idea is insufficient against the determined system cracker. In throwing away all the "here" document, it is ignoring a big hole. Try the following (works in both csh and sh here): cat <<eof `date` eof You get the current date on the output. So your system cracker can still insert any random command into the 'here' text and sharks will not detect it. Oh well. -- =Spencer ({ihnp4,decvax}!utah-cs!thomas, thomas@utah-cs.ARPA)
