Re: Problem with positional output

Yes, an example usually helps, prevents misinterpretation. I tried to 
provide one:

$ cat example.txt
param 1|param 2|param 3|param 4

The suggested sed solution does not work correctly, as the first .* is 
greedy and gobbles up the first '|' character:

$ sed 's!\(.*\)|\(.*\)|\(.*\)!\1!' example.txt
param 1|param 2

Adding one more 'hold pattern' works correctly, I think.

$ sed 's!\(.*\)|\(.*\)|\(.*\)|\(.*\)!\1!' example.txt
param 1

Instead of .* one could also use [^|]* expression.
