Redirecting stdout into several programs

[LonelyStar]

Hi,

I want to write a bash script wich analyzes an email, it gets from stdin using the mess822 packet.
I want to extract the from and the to field.
I can extract the from field like this:

from_line=`822field from`

Which takes stdin and extracts the from field.
Can do the same with the to field, but how can I do both? After the line above, there is no stdin left for

to_line=`822field to`

to analyze. How can I pipe stdin into both comands?

Thanks!
Nathan

Try the 'tee' command. It can copy stdin to stdout and multiple files; you can also copy to stdout more than once.
