You don't need them in the file itself.

^ and $ have special meanings to grep -- ^ means "Beginning of the line", and "$" means "end of the line."

So "^word$" would search for a line that starts, and ends, with word. It wouldn't match "wword" or "wordd".

So this doesn't sound relevant to what you want, since you're not looking for a regex at the beginning or end of a line. You're looking for an exact string in a column.

awk is very good at dealing with columns... How about:

Code:
awk '
# Save the list of strings to look for into the array A, so A["stringtofind1"]=1 etc.
NR==FNR{ A[$1]++; next};

{      # Check each column for the exact string.  If found, print the line and break the loop.
        for(N=1; N<=NF; N++) if(A[$N]) { print ; break }
}' controlfile logfile
