Bash 向csv文件报告谁是ip

我想从ip池文件中读取ip并从中获取whois，然后将其报告到CSV电子表格文件。 我编写此脚本是为了执行以下操作：

#!/bin/bash
echo "ip,netname,org-name,remarks,descr,country,person,address,phone,origin" > csv
while read -r ip
do
whois $ip > whoisip
netname= cat whoisip | grep "netname"
orgname= cat whoisip | grep "org-name"
remarks= cat whoisip | grep "remarks"
descr= cat whoisip | grep "descr"
country= cat whoisip | grep "Country"
person= cat whoisip | grep "person"
address= cat whoisip | grep "address"
phone= cat whoisip | grep "phone"
origin= cat whoisip | grep "origin"
echo $ip,$netname,$orgname,$remarks,$descr,$country,$person,$address,$phone,$origin >> csv
done <pool

为什么第二个值为空？

我试图修复您的脚本：

#!/bin/bash
echo "ip,netname,org-name,remarks,descr,country,person,address,phone,origin" > csv
while read -r ip
do
    whois $ip > whoisip
    netname=`cat whoisip | grep -i "netname"`
    orgname=`cat whoisip | grep -i "org-name"`
    remarks=`cat whoisip | grep -i "remarks"`
    descr=`cat whoisip | grep -i "descr"`
    country=`cat whoisip | grep -i "Country"`
    person=`cat whoisip | grep -i "person"`
    address=`cat whoisip | grep -i "address"`
    phone=`cat whoisip | grep -i "phone"`
    origin=`cat whoisip | grep -i "origin"`
    echo $ip,$netname,$orgname,$remarks,$descr,$country,$person,$address,$phone,$origin >> csv
done <pool

“var=”后面不能跟空格。“var=cat whoisip | grep“netname”将尝试将var设置为字符串，而不是grep的输出。例如，请改用NETNAME=“$（grep NETNAME whoisip）”。注意，变量名应该大写，grep的输出应该被引用。有关其他几个指针，请参阅。我替换了NETNAME=“$（grep NETNAME whoisip）”，但第二个值仍然为空<代码>网络名称！=

NETNAME

谢谢大家，我的问题通过shellcheck.net解决了。

#!/bin/bash
echo "ip,netname,org-name,remarks,descr,country,person,address,phone,origin" > csv
while read -r ip
do
    whois $ip > whoisip
    netname=`cat whoisip | grep -i "netname"`
    orgname=`cat whoisip | grep -i "org-name"`
    remarks=`cat whoisip | grep -i "remarks"`
    descr=`cat whoisip | grep -i "descr"`
    country=`cat whoisip | grep -i "Country"`
    person=`cat whoisip | grep -i "person"`
    address=`cat whoisip | grep -i "address"`
    phone=`cat whoisip | grep -i "phone"`
    origin=`cat whoisip | grep -i "origin"`
    echo $ip,$netname,$orgname,$remarks,$descr,$country,$person,$address,$phone,$origin >> csv
done <pool

var=value  #Correct -> var has the value value
var= value #Incorrect -> var is empty
