FSPEC(5)

NAME
fspec - format specifications in text files

DESCRIPTION
The ed(1), newform(1), and tabs(1) utilities are able to read a tabulator specification from the first line of a file. The general format of format specification lines is

    <:fspec:>

other characters (specifically comment characters for the actual file format) may surround the format specification. fspec consists of multiple fields separated by spaces. Each field starts with a single character giving its type; the characters interpreted by the tools in this collection are:

t   Followed by a tabspec as described in tabs(1). For example, the line `<:t-c2:>' selects COBOL compact format.

s   Followed by a number; causes the output line to be truncated at the given column.
