Well, if your interested anyway...
Code:
 awk -F\| '{ for(i=1;i < NF;i++) { if(i > 1) printf("|"); printf("%s",$i); } print ""; }'  infile

Code:
awk -F '|'  'BEGIN { OFS="|" }
                 { $NF="" ; print }
'   infile

And if like remove last |
then
Code:
awk -F '|'  'BEGIN { OFS="|" }
                 { $NF="" ; print }
'   infile | sed 's/|$//'

using shell
Code:
cat infile | while read line
do
        echo "${line%|*}"
done

Awk (and sed for that matter) never cease to amaze me...
I always write too much of a "program" when I do mine...

Couple of small issues - dont know if they're a problem.
Field separator of pipe goes missing, and there is an extra separator on the end...

sorted:
Code:
awk -F '|'  '{ OFS="|"; NF-- ; print }'
