two useful scripts

• pgbench_suite.sh

- Use pgbench to benchmark a postgresql database
- “-m 1″ show sharedmem, “-m N” set sharedmem to N mb
- “-a” to help or just edit the first lines to configure it.

• sub2vid.sh

- Use mencoder/mplayer to add a subtitle file into a video file or to reencode it in other format.
- “-h” to help or edit the first lines to configure.

Enjoy :)
