try:
Code:
awk -F"[.]" '{print $1}' 123.dat

also:
Code:
sed 's/[.].*//' 123.dat

also:
Code:
cut -d . -f 1 123.dat

also:
Code:
while read i ; do echo ${i%.*} ; done < 123.dat

There are many other utilities that can return the first field of a record based on a delimiter but I do not think the cat command has any arguments that delimits fields.
