cowsay 命令很有趣，显示器上面显示一头奶牛。cowsay 基本上是一个文本过滤器。向其中发送一些文本，你就会得到一头奶牛说出你的文本。如果你觉得一头会说话的奶牛还不够，奶牛也会思考。你所要做的就是运行 cowthink。
cowsay [-bdgpstwy] [-h] [-e eyes] [-f cowfile]
[-l] [-n] [-T tongue] [-W wrapcolumn] [message]
FILE The CSV file to operate on.
If omitted, will accept input as piped data via STDIN.
The -W specifies roughly (where the message should be wrapped. The default is equivalent to -W 40 i.e. wrap words at or before the 40th column.
If any command-line arguments are left over after all switches have been processed, they become the cow's message. The program will not accept standard input for a message in this case.
There are several provided modes which change the appearance of the cow depending on its particular emotional/physical state. The -b option initiates Borg mode; -d causes the cow to appear dead; -g invokes greedy mode; -p causes a state of paranoia to come over the cow; -s makes the cow appear thoroughly stoned; -t yields a tired cow; -w is somewhat the opposite of -t, and initiates wired mode; -y brings on the cow's youthful appearance.
The user may specify the -e option to select the appearance of the cow's eyes, in which case the first two characters of the argument string eye_string will be used. The default eyes are 'oo'. The tongue is similarly configurable through -T and tongue_string; it must be two characters and does not appear by default. However, it does appear in the 'dead' and 'stoned' modes. Any configuration done by -e and -T will be lost if one of the provided modes is used.
The -f option specifies a particular cow picture file (''cowfile'') to use. If the cowfile spec contains '/' then it will be interpreted as a path relative to the current directory. Otherwise, cowsay will search the path specified in the COWPATH environment variable. To list all cowfiles on the current COWPATH, invoke with the -l switch.
If the program is invoked as cowthink then the cow will think its message instead of saying it.
