Re: How to grep some string(IP:port) from text file and print into txt file

Do you really want to grep your input? Grepping the input would essentially means to filter out some lines and keep the others. It seems (although your post is not entirely clear about what you want) that you only want to keep the first "field".

Here's a possible oneliner doing that:

$ echo '
> |    94.17.166.233:5060    |    unknown    |    disabled    |
> |    94.17.201.7:5060    |    unknown    |    disabled    |
> |    94.17.238.174:5060    |    unknown    |    disabled    |
> |    94.17.25.93:5060    |    unknown    |    disabled    |
> |    94.17.174.32:5070    |    unknown    |    disabled    |
> |    94.17.153.2:5080    |    unknown    |    disabled    |
> |    94.17.253.74:9999    |    unknown    |    disabled    |
> |    94.17.78.65:5060    |    unknown    |    disabled    |
> |    94.17.116.247:5060    |    unknown    |    disabled    |
> |    94.17.201.223:5060    |    unknown    |    disabled    |
> |    94.17.194.127:5060    |    unknown    |    disabled    |
