## Install

## lis(1)

check for indent style

## Synopsys

	lis [-s tab|space] [file ...]

## Description

The `lis` utility prints a set of errors to standard error if there are
lines inside each `[file ...]` that don't use `[-s]` for indenting.
If `[-s]` is not specified, the default value is `tab`. If `[file ...]`
is absent, `lis` reads from standard input.

## Exit Status

The `lis` utility exits `0` on success, and `>0` if an error occurs.

## Examples

Check for spaces indenting

	$ echo " bar" > foo
	$ lis foo
	:1:1: Spaces detected

Check for tabs indenting

	$ echo "	bar" > foo
	$ lis -s space foo
	:1:1: Tabs detected

## lts(1)

## Synopsys

	lts [file ...]

## Description

The `lts` utility prints a set of errors to standard error if there are
lines inside each `[file ...]` that has trailing tabs or spaces

## Examples

Check for trailing tabs

	$ echo "bar    " > foo
	$ lts foo
	:1:4: Trailing tabs detected

Check for trailing spaces

	$ echo "bar " > foo
	$ lts foo
	:1:4: Trailing spaces detected

## lml(1)

check for maximum line length

## Synopsys

	lml [-l num] [file ...]

## Description

The `lml` utility prints a set of errors to standard error if there are
lines inside each `[file ...]` that exceed `num` characters. If `num`
is not specified, the default value is 72 characters. If `[file ... ]`
is absent, `lml` reads from standard input.

## lfn(1)

check for final newline

## Synopsys

	lfn [file ...]

## Description

is missing the final newline. If `[file ...]` is missing, `lfn` reads
from standard input.

## Exit Status

The `lfn` utility exits `0` on success, and `>0` if an error occurs.

## Examples

Check for missing final newline

	$ echo "bar" > foo
	$ printf "baz" >> foo
	$ lfn foo
	foo: Missing final newline

## ltn(1)

## Synopsys

	ltn [file ...]

The `ltn` utility prints an error to standard error if any `file ...`
has trailing newlines. If `[file ...]` is missing, `ltn` reads from
standard input.

## Exit Status

The `ltn` utility exits `0` on success, and `>0` if an error occurs

## Examples

Check for trailing newlines

	$ echo "bar" > foo
	$ echo "baz" >> foo
	$ printf "\n" >> foo
	$ ltn foo
