7.1 Appendix A - A script for creating host directories

#!/usr/bin/bash
#This is a script for creating host directories using the
#directory scheme illustrated before in this document.
#It is written on Solaris and I did not test it on Linux.
#Execute it at the ws directory.
#Needs as input a file containing space separeted IP
#addresses named addr, for example bash# ./script addr
#This file must be like this: 195.251.160.10 195.251.160.11 195.251.160.13 ....

#Do not forget to edit the i variable and the while statement to specify
#the range of the addresses you want to ping
