Force shutdown of a Linux server

This could be useful when you really need to shutdown... some kind of a "Vulcan Key" to the kernel :)

#echo 1 > /proc/sys/kernel/sysrq
#echo o > /proc/sysrq-trigger

Log transfer and update script

The ideas of this script are:
-Download all the files for yesterday (the date must be inside the filename) and save in disk for 61 days.
-Download all the new files generated any day for other days (something like "residual logs... the system generates the log for the day n-1 the n day, but maybe any of the n-m (m<61) day, the system generates another log for any of the n-m days... and the script must download it, verifying the content for every day in the ftp against the disk... it's that clear :P

So, it's not very finished yet, but here is:
(I know, all the comments and vars are in spanish... but just watch a Cheech and Chong's movie and you'll be ok)

AYER=`/bin/date +"%Y%m%d" --date "24 hour ago"`
LOGFILE="/path/to/log"
REMOTEHOST="x.x.x.x"

PASS="pass"
DESTINO="/path/to/disk"

#### ARCHIVOS MENSAJERIA DIA ANTERIOR
