替代猫了一个bash脚本的？ [英] Alternative to Cat out of a bash script?

问题描述

我有以下的问题。

exec 3<>/dev/tcp/$1/37491

echo -ne 060e2b3 00$hexdec$cmdhex | perl -pe 's/([0-9a-f]{2})/chr hex $1/gie' >&3

cat <&3

我有我一个十六进制字符串发送到与所取得的端口/ tcp连接的服务器。但由于我通过一个终端使用腻子我的第一个问题是，XML响应返回总是说腻子和它不逃避。我也需要把后面的答复有时在数组中，我曾尝试

i have a server in which i send a hex string to with the port / tcp connection made. BUT since i am using putty through a terminal my first issue is that the XML response back always says PuTTY and it doesnt escape. I also need to put the replies back sometimes in an array and i have tried

array=`cat <&3`

echo "Array items:"
for item in ${array[*]}
do
    printf "   %s\n" $item
done

和我相信，因为猫不正确退出它只是保持打开阵列不这样做？

and i believe since the cat is not exiting properly it just stays open the array is not done?

推荐答案

你需要指定一个超时？

while read -t 5 line <&3; do 
    echo "$line"
    (( Lines++ ))
done
exec 3>&-
