variable from command

Hi, I'm trying to use a variable I receive from a command in my script but it doesn't seem to work.


Code:
cat $1|sed -n 's/.*\(|.*|.*|\).*/\1/p'|sed 's/|\(.*\)|.*|/\1/'

I need the output from that as my var. I tried with = before the command and after but that didn't seem to work.
$1 is file a were it filters out a string of text with sed.

Solutions?

Try this, it will read the value from user and frame the command to execute.
Code:
read var; cat $var | sed -n 's/.*\(|.*|.*|\).*/\1/p'|sed 's/|\(.*\)|.*|/\1/'

Code:
var=`sed -n 's/.*\(|.*|.*|\).*/\1/p'|sed 's/|\(.*\)|.*|/\1/' $1`

or
Code:
var=$(sed -n 's/.*\(|.*|.*|\).*/\1/p'|sed 's/|\(.*\)|.*|/\1/' $1)

Jean-Pierre.

None of the above seem to do what they should, maybe I should also mention, this variable needs to be the name of a file followed by an extension. at the moment I'm running the script but It doesn't do anything.
