How to get the cursor position in bash?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: In a bash script, I want to get the cursor column in a variable. It looks like using the ANSI escape code {ESC}[6n is the only way to get it, for example the following way: # Query the cursor position echo -en '\033[6n' # Read it to a variable read -d R CURCOL # Extract the column from the variable CURCOL="${CURCOL##*;}" # We have the column in the variable echo $CURCOL Unfortunately, this prints characters to the standard output and I want to do it silently. Besides, this is not very portable... Is there a pure-bash way to achieve this ?

How would you get it to return the strings surrounding the cursor / selection? E.g.: 'This is', '', ' a text' . If the word “is” is highlighted, then it would return 'This ', 'is', ' a text' . 回答1: With Firefox, Safari (and other Gecko based browsers) you can easily use textarea.selectionStart, but for IE that doesn't work, so you will have to do something like this: function getCaret(node) { if (node.selectionStart) {

I'd like to do it in pure CSS, are there any methods? 回答1: If the parent element has a solid color background, you can use pseudo-elements to create the effect: div { height: 300px; background: red; position: relative; } div:before { content: ''; position: absolute; top: 0; right: 0; border-top: 80px solid white; border-left: 80px solid red; width: 0; } http://jsfiddle.net/2bZAW/ P.S.
