.TH LOWERCASE 1

.SH NAME

lowercase \(en make text lowercase

.SH SYNOPSIS

lowercase (-f)

.SH DESCRIPTION

Lowercase prints text from standard input to standard output as lowercase.

.SH DIAGNOSTICS

Lowercase will print an error message and exit with the appropriate status from sysexits(3) if it attempts
to process a glyph outside the supported encoding range; this is to not inadverdently mangle multi-byte
characters. The -f option exists to override this and process every character anyway.

.SH BUGS

Lowercase is not Unicode aware unless it's compiled with the USE_ICU flag, which requires libicu.
This isn't tested to any extent.
.PP
Lowercase is redundant to usages of tr(1) among other POSIX-specified utilities.

.SH HISTORY

Lorinda Cherry demonstrates using a lowercase utility in the AT&T film
.I UNIX: Making Computers Easier To Use.
