Can I grep only the first n lines of a file?
...awk for a single process without |:
awk '/your_regexp/ && NR < 11' INPUTFILE
On each line, if your_regexp matches, and the number of records (lines) is less than 11, it executes the default action (which is printing the input line).
Or use sed:
sed -n '/your_regexp/p;10q' INPUTFILE
