# The `s6-head` program

s6-head prints the first lines of its input files.

## Interface

         s6-head [ -S ] [ -1..9 | -n lines | -c chars ] file...

s6-head acts as the generic head utility.

## Extra options

- `-S` : safe mode. s6-head stops reading its input files right after getting all the lines it needs. The rest of the stream can then be handled by other utilities without any data loss.
- `-1..9` : equivalent to `-n 1` .. `-n 9`.
- `-c` chars : cuts after chars characters instead of lines lines.

## Posixness

s6-head is suitable as a Single Unix head program.
