Genesis2000脚本命令大全1.switch的用法,注意每一个case必须要以breaksw结尾否则会继续执行下一个case的命令(1)另外,$<的意思是取得使用者的stand input(2)echo若加上-n的选项,则游标会停留在该行最后echo-n"Input one color:"set STOPLIGHT=$<switch($STOPLIGHT)case red:echo"red"breakswcase orange:echo"orange"breakswcase green:echo"green"breakswdefault:echo"you input$STOPLIGHT"endsw--------------------------------------------------------------------2.利用set来取得变数,set ABC="I am ABC"也可以利用`command`来取得命令且外,case也可以用万用字元*来代替set VER=`uname-r`switch($VER)case5.5:echo"run the setup of$VER"breakswcase5.3:echo"run the setup of$VER"breakswcase5.*:echo"like5.x"breakswcase4.*:echo"like4.x"breakswdefault:echo"no

ok"endifendifend#后来看过sed的更进一步用法,发现先前写的太笨了,试试这个#sed/font/d$file>${file}1#一次OK,我真是大笨蛋--------------------------------------------------------------------11.功能:将指定的档案中,出现第一次【回】的那一行,加上<ti tle>xxxx</title>foreach file(sky*.html)set filetitle=ftitle#主要部份为sed部份s/^*//表示将该行第一个字元前的空白删除echo"<title>`grep回$file|head-1|sed-e's/^*//'`</tit
