I have a file test.txt, it is a very large file, want to create another file test1.txt, which has only first 10 lines of test.txt

How can I do that from unix command?

Thanks

Hi,

just do as follows:
cat text|head > text1

If you want more than 10 lines use
cat text|head -20 > text2

Hi,

just type the following:

cat dept.dat | head > dept1.dat

or if you want more than 10 lines:
cat dept.dat | head -20 > dept2.dat

or see man head, man tail

Reagrds,
