Because I only wanted the first line. Sometimes

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.

With sed I can pick out what line or lines I want. Makes it universal. Once I learn how to do something I tend to stick with it.
With Linux, here is always 11 ways of doing everything. With Raku (Perl 6) there is always 101 ways of doing everything.
Makes both Linux and Raku fun to work with. I do program somewhat in Windows, but it is no where near as much fun.
