a bash question about while

hello

when I run this at command-line mode:

Quote:

[root@localhost ~]# addr=221.216.157.121:3128
[root@localhost ~]# echo "http://"$addr"/"
http://221.216.157.121:3128/

that is ok!

but, if I run it within while on a bash-script:

Quote:

while read line
do
http_proxy="http://"${line}"/"
echo ${http_proxy}
done < httpname

httpname file content is 221.216.157.121:3128

but echo ${http_proxy} display \/tp://221.216.157.121:3128

why, and thx for any idea.

All I can say is: "Works for me"

Did you copy and paste the IP into the file
somehow? Maybe have a look with a hex
editor or something?

Cheers,
Tink

Do you get the same behaviour if you change

Code:

echo ${http_proxy}

Code:

echo "${http_proxy}"

Also, you're not actually quoting the $(line) part of the assignment, you don't need the inner pair of quotes.

thx eddiebaby1023,but .....

I try the method as your suggestion, but still failed

and , I find the line

Quote:

http_proxy="http://"${line}

must change as

Quote:

http_proxy='http://'${line}

then , the bash script work fine.
