These are all the dirs in my server:

? bin boot dev etc home lib lost+found media media2 misc mnt net opt proc root sbin selinux srv sys tmp usr var

why there is a "?" dir?

Thanks very much.

BTW: the touch command was found on my server(wiered).

I list the bin dir:

alsacard cp dd env hostname loadkeys more ps sed tcptraceroute alsaunmute cpio df ex igawk loadkeys.static mount pwd setfont traceroute6 arch csh dmesg false ipcalc logger mountpoint raw setserial tracert awk cut dnsdomainname fgrep kbd_mode login mv red sh view basename date doexec gawk keyctl ls netstat redhat_lsb_init sleep ypdomainname bash dbus-cleanup-sockets domainname gettext kill mail nice rm sort cat dbus-daemon dumpkeys grep ksh mailx nisdomainname rmdir stty chgrp dbus-monitor echo gtar ksh93 mkdir pgawk rpm su chmod dbus-send ed gunzip link mknod ping rvi sync chown dbus-uuidgen egrep gzip ln mktemp ping6 rview tar

touch is missing, how can i get it back?
