bitterbpp

Description: bitterbpp is Linux DVD ripping software, a GUI interface for MPlayer, specifically for transcoding DVD titles (video, audio, and subtitles) to Matroska file format. It has some nice features.

Free Download

Disclaimer: bitterbpp may not be used to make illegal copies of DVD movies; in fact, it functionally cannot since it depends entirely on MPlayer and lsdvd to read and process the DVD structure. So if you cannot legally (local laws, etc) make a backup copy of a DVD you legally own, you may not use this software in conjunction with MPlayer to do so. In fact, if for you the previous statement is true, I wouldn't even visit the MPlayer site, let alone download MPlayer.

Design: bitterbpp is designed as a lightweight, feature rich GUI "wrapper" to MPlayer, lsdvd and various other related software. As such, bitterbpp is an application written in Perl, utilizing the Gtk+ 2.x Perl bindings. Since it has some typically non-portable methods and system calls designed for Linux compatible systems, I don't suggest using this in any untested environment (Mac OS X, Windows, etc).

Feature list: Recompresses any selected movie track in 2 passes (or n passes if desired) using one of four configurable codecs, to fit chosen space and scaling requirements. Scaling calculations are based on bits per pixel estimates, hence the name bitterbpp; Unlimited audio tracks (in original AC3 or DTS, or recompressed to OGG Vorbis) and unlimited subtitle tracks, with proper language support.

Argument list too long when copying/deleting/moving files on Linux

If you do a lot of command line stuff in Linux, sooner or later you'll come across the "argument list too long" error when copying, moving, deleting, listing etc files in a directory that contains a lot of files. This post looks at a couple of ways of solving this problem.
will result in errors like this:

-bash: /bin/mv: Argument list too long
-bash: /bin/cp: Argument list too long
-bash: /bin/rm: Argument list too long
-bash: /bin/ls: Argument list too long

To workaround the problem you can use xargs or find, or a combination of the two.

Using the "ls" command, you could do this to move all the files from source into target:

ls -1 ./*.dat | xargs -i mv {} /home/user/targe/

Using find to do the same move from source to target, you could do this:

find . -name "*.txt" -maxdepth 1 -exec mv {} /home/user/targe/ \;

or this, using xargs instead of the -exec flag:

find . -name "*.txt" | xargs -i mv {} /home/user/targe/
