FFM(1)

NAME
	ffm

SYNOPSIS
	kirara/ffm [-f $num] [-F $sep] [-v] [-m] [-K] $pat_file [$file ....]

DESCRIPTION
	Ffm reads files in the arguments and shows lines that match one of
	strings in $pat_file.
	
	Ffm is different from grep in that it understands fields and
	the matching is fields oriented. On the other hand the matching is
	simple match, not regular expression.

	The options are
	 -f $num: $num is a field number that begins with 1,2,...
	 -F $sep: field separator
	 -v : show lines that do not match the pattern.
	 -m : substring match from the beginning of field.
	 -K : append matched key length at the end of field.
	If $num not be given, then ffp shows lines if one of the fields matches
	to one of strings in $pat_file.
	If $sep is zero length string, then lines are single field.

	There are many examples that grep is not suitable to resolve.
