我正在尝试做两件事:1.测试IP地址的有效性。2.在具有多个IP地址的文件中搜索IP地址。“ ips”是文件。到目前为止,这就是我所拥有的。每次我运行脚本时,都会得到以下信息:ip地址是否在文件中都无所谓,我总是会得到“未找到并保存IP地址”。请帮忙。谢谢高级
$ ./test1
IP address: 202
Not Valid. Please re-enter the ip address
IP address: 202.124.64.0
IP address NOT found, and saved
IP address: 109.234..232.0
Not Valid. Please re-enter the ip address
IP address: 109.234.232.0
IP address NOT found, and saved
剧本:
#!/bin/bash
while true; do
echo -e "IP address: \c"
read ip
function valid_ip()
{
local stat=1
if [[ $ip =~ [0-9]{1,3}\.[0-9{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ ]]; then
OIFS=$IFS
IFS='.'
ip=($ip)
IFS=$OIFS
[[ ${ip[0]} -le 255 && ${ip[1]} -le 255 && ${ip[2]} -le 255 \
&& ${ip[3]} -le 255 ]]
stat=$?
fi
return $stat
}
if valid_ip $ip; then
if grep 'valid_ip $ip' ips; then
echo "IP address found, and saved"
else
echo "IP address NOT found, and saved"
fi
else
echo "Not Valid. Please re-enter the ip address"
fi
done
保持这样的功能:
valid_ip() {
local stat=1
ip="$1"
if [[ $ip =~ [0-9]{1,3}\.[0-9{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ ]]; then
OIFS=$IFS
IFS='.'
a=($ip)
IFS=$OIFS
[[ ${a[0]} -le 255 && ${a[1]} -le 255 && ${a[2]} -le 255 && ${a[3]} -le 255 ]]
stat=$?
fi
return $stat
}
然后将其称为:
while true; do
reap -p "Enter an IP address: " ip
if valid_ip $ip; then
echo "IP address found, and valid"
break;
else
echo "Not Valid. Please re-enter the ip address"
fi
done
