How can I get the source code for the linux utility tail?


linux tail uclinux

The tail utility is part of the coreutils on linux.

I've always found FreeBSD to have far clearer source code than the gnu utilities. So here's tail.c in the FreeBSD project:

linux tail uclinux

Poke around the uclinux site. Since they distributed the software, they are required to make the source available one way or another.

Or, you could read man fseek and guess at how it might be done.

NB-- See William's comments below, there are cases when you can't use seek.

linux tail uclinux

You might find it an interesting exercise to write your own. The vast majority of the Unix command-line tools are a page or so of fairly straightforward C code.

To just look at the code, the GNU CoreUtils sources are easily found on gnu.org or your favorite Linux mirror site.
