Check These Out
Takes all the .3gp files in the directory, rotates them by 90 degrees, and saves them in the lossless ffv1 encoding.
If this rotates in the wrong direction, you may want transponse=1
Re-encoding to ffv1 may result in a significant increase in file size, as it is a lossless format. Other applications may not recognize ffv1 if they don't use ffmpeg code. "huffyuv" might be another option for lossless saving of your transformations.
The audio may be re-encoded as well, if the encoding used by your 3gp file doesn't work in a avi container.
from my bashrc ;)
This command lets you select from 10 different BBC stations. When one is chosen, it streams it with mplayer.
Requires: mplayer with wma support.
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22)
(all files & folders on destination server/folder will be deleted)
parallel can be installed on your central node and can be used to run a command multiple times.
In this example, multiple ssh connections are used to run commands. (-j is the number of jobs to run at the same time). The result can then be piped to commands to perform the "reduce" stage. (sort then uniq in this example).
This example assumes "keyless ssh login" has been set up between the central node and all machines in the cluster.
bashreduce may also do what you want.
G - uses VT100 line drawing
a - shows command line arguments of process
p - prints PID of process
For other options, man pstree :)
This command will tell lynx to read keystrokes from the specified file - which can be used in a cronjob to auto-login on websites that give you points for logging in once a day *cough cough* (which is why I used -accept_all_cookies).
For creating your keystroke file, use:
$ lynx -cmd_log yourfile
Nothing advanced, it just finds filenames that are stored with ISO-8859-1 characters and and converts those into UTF-8. Recommended to use without the --notest flag first so you can see what will be changed.
