No, I meant bs=3. That is what it seemed to require from empirical testing.

You are correct. It appeared to require it but that was my mistake (probably from still using the sync option at the time).

You might even do bs=4M.

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 SEE ALSO
