Summary: lost+found for SysV


According to the System V Admin Guide (c) 1985, pg 3-34, 3-35:

	"As a general guide, the number of [i-node] slots to reserve
	 is about ten percent of the number of i-nodes allocated for
 	 the file system."

The following shell script accepts as argument $1 the number of
inodes in the file system, then creates files in modulo 50 increments
up to 10% of the argument.  Your current directory should be
the empty file system.


Note:  the "rm" statements at the end of this script may blow up if the
	file system is sufficiently large (error is "arg list too big" or
	some such nonsense). If this happens, change the lines to:

		rm [A-M][0-9]*
		rm [M-Z][0-9]*   etc.

	or just try rm *

if [ "${#}" -gt "1" ] | [ "${#}" = "0" ]
then
	echo "Usage:  $0 n"
	echo "	where n = number of i-nodes in file system."
	exit 1
fi

# Loop for mod 50 of 10% of $1

n=`expr \( \( $1 / 10 \) +1 \) /50`
if [ "$n" = "0" ]
then
	n=1
fi

#  Create 50 files at a time
