Dumping Audio stream from flv (using mplayer)

List detailed information about a ZIP archive
list zipfile info in long Unix ``ls -l'' format.

Remount an already-mounted filesystem without unmounting it
Necessary for fsck for example. The remount functionality follows the standard way how the mount command works with options from fstab. It means the mount command doesn't read fstab (or mtab) only when a device and dir are fully specified. After this call all old mount options are replaced and arbitrary stuff from fstab is ignored, except the loop= option which is internally generated and maintained by the mount command. It does not change device or mount point.

List the URLs of tabs of the frontmost Chrome window in OS X
This also works with Safari if you just change the application name. Replace $ window 1 with $ windows to list the URLs of tabs in all windows instead of only the frontmost window. This also includes titles: $ osascript -e{'set o to""','tell app"google chrome"','repeat with t in tabs of window 1','set o to o&url of t&"\n"&" "&title of t&"\n"',end,end}|sed \$d .
