问题 So, here's what I have: I created a small batch file to record the results of a ping test to a text file.

Ideally, the output would be something like this: updated: userData.txt renamed: picture.jpg -> background.jpg copied: song.mp3 -> song.mp3.bkp Is it possible? --name-status also doesn't

问题 I have a php script that generates a pdf report. When we go to save the pdf document, the filename that Acrobat suggests is report_pdf, since the php script is named report_pdf.php. I would like to dynamically name the pdf file, so I don't have to type the appropriate name for the report each time that I save it. Asking on a news group, someone suggested this, where filename="July Report.pdf" is the intended name of the report <? header('Content-Type: application/pdf'); header('Content

问题 When my team first started out with SVN we all just used our first names when committing to the repository, however, now that our team has grown, we are running into issues because we just hired a second Mike . What we would like to do is change everybody's usernames to be the same as the username on their computer (first name initial + last name).
