I installed Cygwin, choosing a fairly minimal set of packages. In a terminal, I tried to do 'clear' to clear the terminal, but I get bash: clear: command not found How do I get this to work? Marnix Klooster Install the Cygwin package ncurses ; it is in the Utils category. Krishna Murthy This should do: alias clear='printf "\033c"' just use this shortcut: Alt+F8 and Ctrl-L to skip page Jared French It's nice to have the clear.exe program for bash script files, so: Windows Cygwin detail for clear.exe program command. Download Cygwin setupx86.exe or whatever it's call at http://cygwin.com/ Run it

I'm trying to create a simple app that draws rectangles within the Canvas tag. I've got the Canvas resizing to fullscreen, but whenever I resize the viewport, Canvas clears. I'm trying to prevent it from clearing and just keeping the content thats within it. Any ideas? http://mediajux.com/experiments/canvas/drawing/ Thanks! /* * This is the primary class used for the application * @author Alvin Crespo */ var app = (function(){ var domBod = document.body; var canvas = null; var canvasWidth = null; var canvasHeight = null; return { //Runs after the DOM has achieved an onreadystatechange of

This is a design question, concrete code not submitted to protect my bottom. When working with Hibernate the standard workflow is as follows: Open Session Start Transaction Do the business (read and modify data) Commit Transaction Close Session with possibly iterations through 2-4. What are reasonable use cases for Session.clear()? A: The concrete problem I have is a (big) piece of code which loads and modifies entities, then clear()s the session, essentially throwing away the changes that were made. (The business task to be accomplished does not include modifying the entities, so the code

I have been pulling my hair for this since quite long time. I have researched for an hour on how to clear a console in Java. All I found was dirty hacking either by printing a bunch of lines or executing this Runtime.getruntime.exec("cls/clear"); However, nothing seems to be working for me. Isn't there really any a way of clearing the console in Java like in C ( clrscr(); ). Isn't there any external library by which this can be achieved. Please let me know if anyone has ever done this before using a proper function, library etc. instead of dirty hacking. If your terminal supports ANSI escape

I look on Stack Overflow, and didn't find the solution, I know how to override style if style exists, just change its property. But now I have a strange style to override Here is an example of what I have First I have this one: .slikezamenjanje img{ max-width: 100%; max-height:150px; padding-right:7px; } Now I need to override that style with just this one: #zoomTarget .slikezamenjanje img { max-width: 100%; } The problem is that first style appends second, but I don't want that, in this second style what I need is just one line, not to append from the first style? Instead of override you can

How do I clear all the EditText fields in a layout with a Clear Button . I have a registration Activity that has about 10 different EditTexts . I know I could go and grab a reference to each specifically and then set.Text("") ; But I am looking for a more dynamic elegant way. Possibly grab the Layout and loop through all the items in there looking for EditText types and then setting those to "" . Not sure how to do that though and tried searching on the web for it but no luck. Any sample code? necixy The answer by @Pixie is great but I would like to make it much better. This method works fine

I know the clear command that 'clears' the current screen, but it does this just by printing lots of newlines - the cleared contents just get scrolled up. Is there a way to completely wipe all previous output from the terminal so that I can't reach it even by scrolling up? Alok Singhal To clear the terminal manually: ⌘ + K Command + K for newer keyboards To clear the terminal from within a shell script; /usr/bin/osascript -e 'tell application "System Events" to tell process "Terminal" to keystroke "k" using command down' A better way to clear screen from within a script...

This question already has an answer here: Why is my function call that should be scheduled by setTimeout executed immediately? [duplicate] 3 answers I want to let an element fade in, and stay on the page for 7 seconds before it fades out. And I can cancel it anytime. I defined the following functions. But when I called info_timeout.setup(ele, 'some msg here') , the ele just faded in and faded out immediately. Am I missing something? var info_timeout = { show_info: function(){ this.ele.html(this.msg).fadeIn('normal'); this.id = setTimeout(this.hide_info(), 7000); }, hide_info: function(){
