My dear friend, recently I was frustated by bioinformatic homework. It is abut
unix, so I come here to get help.
write a command that copies the last 100 lines of the one log file to a file
in your home directory.
Thanks a lot!

I think it might be "tail" instead of last.
tail -n 100 log_file > ~/

: last -n 100 log_file > ~/

Thanks, it works! When I open the new file (the oringinal file is
access_log)in my home directory and try to read it, it says "wtmp begins Tue
Dec 21 17:12:55 2004", what is means? Thanks!
