LESSECHO(1) General Commands Manual LESSECHO(1)NAME
lessecho - expand metacharacters, such as * and ?, in filenames on Unix systems.
SYNOPSIS
lessecho [-ox] [-cx] [-pn] [-dn] [-a] file ...
DESCRIPTION
This manual page documents briefly the lessecho command. This manual page was written for the Debian GNU/Linux distribution because the
original program does not have a manual page.
lessecho is a program that simply echos its filename arguments on standard output. But any argument containing spaces is enclosed in
quotes.
OPTIONS
A summary of options are included below.
-ox Specifies "x" to be the open quote character.
-cx Specifies "x" to be the close quote character.
-pn Specifies "n" to be the open quote character, as an integer.
-dn Specifies "n" to be the close quote character, as an integer.
-a Specifies that all arguments are to be quoted. The default is that only arguments containing spaces are quoted.
