Quick Start

You need to have Rust installed.

# Install latest *release* version of headtail
$ cargo install headtail

# Install local development version of headtail from inside the git repo
$ cargo install --path .

# Use it on a file - prints the first 10 and last 10 lines
$ headtail somebigfile.txt

# Pipe stdout to it - prints the first 10 and last 10 lines
$ somecommand | headtail

# Print the first 25 and last 5 lines of a file
$ headtail somebigfile.txt -H 25 -T 5

# Print the default amount of first lines, but only 3 last lines
$ headtail somebigfile.txt -T 3

# Do the default thing...but then keep tailing the file and print
# out anything new that is appended to it.
$ headtail somebigfile.txt -f
