comment How do I get the MD5 sum of a directory's contents as one sum?
@CMCDragonkai: What do you mean? In the first case, we do sort the list of file names. In the second case, we purposely do not because part of the emphasized anything in the first sentence is that the order of files in a directory has changed, so you wouldn't want to sort anything.

comment What does :: do in script of sed
Yes, sorry, I assumed you knew enough sed to recognize something like s/foo//, so all I had to do was point out that s:foo:: does the same thing. Both mean "Remove the first instance of foo on each line of the input when writing to the output."

comment Why can't close my eth0 by command `ifconfig eth0 down`?
@it_is_a_literature: Are you certain your system actually has an eth0? I know it shows up in the list above, but that could just be because of prior misconfiguration. For example, maybe your system is using Consistent Network Device Naming, so your Ethernet interface is called something other than eth0. Or, maybe your system is wifi-only, so there is only wlan0.

@it_is_a_literature: Reboot your box and try again. I suspect your previous manual ifconfig commands have confused the ifdown program.
