Shell Programming and Scripting

The first command enter the returned line into argument line parameter $* (so $1, $2, $3 ...)

see :

Code:

# echo $*

# set -- $(df -k . | tail -1)
# echo $*
/dev/md/dsk/d61 10326524 333529 9889730 4% /export
# echo $1
/dev/md/dsk/d61
# echo $2
10326524
# echo $3
333529
# echo $4
9889730
# echo $5
4%
# echo $6
/export
# echo $*
/dev/md/dsk/d61 10326524 333529 9889730 4% /export
# shift
# echo $*
10326524 333529 9889730 4% /export
# shift
# echo $*
333529 9889730 4% /export
# shift
# echo $*
9889730 4% /export
# shift
# echo $*
4% /export
# shift 2
# echo $*

The second command create a file of count block of 1k .
The count calculation is the total number of block divided by 100 multiplied by the threshold

this give the number of block required to fill up the FS to the wanted threshold, but we have to substract to this number of block, the number of block that are already allocated ($3).

So that count finally match the remaining number of 1K block needed to create the file that will fill the FS at the wanted threshold.

Hello, 2002anand:

What's the point of all this? What are you trying to accomplish?
