默认安装的cygwin的bash shell并没有clear命令，于是有些shell程序需要用到的时候就蛋疼了：

Katherine@cclove ~$ cls-bash: cls: command not foundKatherine@cclove ~$ clear-bash: clear: command not foundKatherine@cclove ~$ which clswhich: no cls in (/usr/local/bin:/usr/bin:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/System32/Wbem:/cygdrive/c/Python27)Katherine@cclove ~$ which clearwhich: no clear in (/usr/local/bin:/usr/bin:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/System32/Wbem:/cygdrive/c/Python27)

搜索并装上ncurses就可以clear了：

Katherine@cclove ~$ which clear/usr/bin/clearKatherine@cclove ~$ ldd /usr/bin/clear        ntdll.dll => /cygdrive/c/WINDOWS/system32/ntdll.dll (0x7c920000)        kernel32.dll => /cygdrive/c/WINDOWS/system32/kernel32.dll (0x7c800000)        cygwin1.dll => /usr/bin/cygwin1.dll (0x61000000)        cyggcc_s-1.dll => /usr/bin/cyggcc_s-1.dll (0x6fcf0000)        cygncurses-10.dll => /usr/bin/cygncurses-10.dll (0x6f9b0000)

实际测试发现不起作用！
Ctrl + l(注意是小写的L)可以实现清屏的效果。
