#!/bin/bash
#del blank lines
#Author Hahazhu 24/12/06
savefile="/tmp/tmp.$$"
function usage(){
echo "Usage:`basename $0` file"
exit 1
}
function notice(){
echo "`basename $0` is not exists"
exit 1
}
if [ $# -eq 0 ];then
usage
else
if [ -r $1 ];then
cat $1|sed "/^$/d"|tee $savefile
echo "Do you want save results?[Y/N]"
read ANS
case $ANS in
Y|y)
mv $savefile $1
if [ $? = 0 ];then
echo "Save ok!"
fi
rm -f $savefile
