1The following are demonstrations of the whatexec.d script. 2 3 4Here we run it while a few commands are also executed, 5 6 # ./whatexec.d 7 PEXEC EXEC OK TYPE 8 bash /usr/bin/clear Y #!/u\0 9 bash /sbin/sh Y \177ELF\0 10 clear /usr/bin/tput Y \177ELF\0 11 bash /export/home/brendan/DOOM.EXE N MZ\644\0 12 ^C 13 14whatexec.d has first found that "clear" was run, which has a type that 15begins with "#!" - a script. clear runs "sh" and "tput", both ELF files. 16 17We finish by attempting to run a MZ file, "DOOM.EXE", which is rejected 18(OK is "N"). 19
