LESSECHO(1) General Commands Manual LESSECHO(1)NAME
lessecho - expand metacharacters
SYNOPSIS
lessecho [-ox] [-cx] [-pn] [-dn] [-mx] [-nn] [-ex] [-a] file ...
DESCRIPTION
lessecho is a program that simply echos its arguments on standard output. But any metacharacter in the output is preceded by an "escape"
character, which by default is a backslash.
OPTIONS
A summary of options is included below.
-ex Specifies "x", rather than backslash, to be the escape char for metachars. If x is "-", no escape char is used and arguments con-
taining metachars are surrounded by quotes instead.
-ox Specifies "x", rather than double-quote, to be the open quote character, which is used if the -e- option is specified.
-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.
-mx Specifies "x" to be a metachar. By default, no characters are considered metachars.
-nn Specifies "n" to be a metachar, as an integer.
-fn Specifies "n" to be the escape char for metachars, as an integer.
-a Specifies that all arguments are to be quoted. The default is that only arguments containing metacharacters are quoted
