Schwanzersatzfaktor-Berechnung
Das folgende Shell-Script (by unbekannt) errechnet den Schwanzersatz-Faktor eines Linux-Rechners:
#!/bin/sh LC_ALL=C echo `uptime|grep days|sed 's/.*up \([0-9]*\) day.*/\1\/10+/'; \ cat /proc/cpuinfo|grep MHz|awk '{print $4"/30 +";}'; free|grep '^Mem' \ |awk '{print $3"/1024/3+"}'; df -P -k -x nfs | grep -v 1k \ | awk '{if ($1 ~ "/dev/(scsi|sd)"){ s+= $2} s+= $2;} END \ {print s/1024/50"/15+70";}'`|bc|sed 's/\(.$\)/.\1cm/'

For each file or directory
for mydir in web* do if [ -d "$mydir" ] then rm -r ./$mydir/generic/ cp -r ./generic/ $mydir echo "$mydir - done" fi done

Rename all files and directorys
This was written for Korn but it probbly works in SH / Bash too it will rename all the file's and directorys in numerical order. be carfull there are no go backs "Why would i want this?" well i could tell you but i would have to...
#!/bin/ksh i=1 echo " have you put this file in the directory you want renameing?" echo "are you shore you want to rename all files?" echo "if so delete the read line below" echo "and the # infrount of the for mv" read for x in `ls | grep -v file.ksh | grep -v moveresults.txt` do i=$(($i+1)); echo $x $i # mv $x $i > moveresults.txt done
Don't do this at home, kids:
bash fork-bomb (will turn your computer into a bomb). may be prevented by using ulimits or other stuff.
