Is this a home work question?

What is the "real world problem"?

i am trying to retrieve all the function call from an obj file and each call ends with values like these so i need to remove them to get only the calls

Should be something like:

sed 's/\([^#]*\)#.*/\1/' file

or:

awk -F# '{print $1}' file

Another way,

cut -d'#' -f1 file
