Interesting. It will print the first lines or the last lines. Thank you!
Sed allows me to pick which ones I want.
'head' prints the first N lines (10 by default). See also 'tail'.
You said you wanted the first line, so 'head' is the obvious command, but as with most things in UNIX/Linux, there is more than one way of doing it.
