Pick a string not whole the line containing that string..Help!

[Guest Networkingkool]

Hi everybody, I am new to this forum. Now I have a trouble and need your helps.

For example: I have a text file (text.txt) containg string : "aaaaaaaaaaaaaa computer adsfjasldkfjasjflk asdlfkjwoeifj 12345"

My Object is to use command line to output only string "12345"

I tried to use command findstr "[1-9]$" C:\123\text.txt. The output of command is exactly the whole line containing the string "12345" not

the string "12345" as I want.

Anyone have better idea?

Thank for any suggest.
