cant use sed or awk
i cant use sed or awk so i was thinking of something like using head and tail to split up the file but it aint working quite right, plus it doesnt fit with the notion of adding any argument
head -$N file > f1
tail -$N file > f2
cat f1 #need to echo and cat $1 here# f2 > newfile
mv! newfile file #needs to retain file name
could n be subbed for a variable that halfs the wc -l or something.
if anyone can shed some differing light upon this idea i wud b eternally grateful
