use a shell script:

for coord in `cat mycoord.txt` ; do 
   east1=`echo $coord  | cut -f1 -d'|'`
   north1=`echo $coord | cut -f2 -d'|'`
   east2=`echo $coord  | cut -f3 -d'|'`
   north2=`echo $coord | cut -f4 -d'|'`
   echo  >> output.txt
   echo "LINE: [$east1, $north1 ; $east2, $north2]" >> output.txt
   r.profile input=foo output=- \
      profile=$east1,$north1,$east2,$north2 >> output.txt
done


that assumes format of mycoord.txt is "east1|north1|east2|north2"
