This is why we need code tags! The command is
Code:
$ ls -la | sed 's/  */|/g'

We need 2 spaces in the sed command. nilesrex probably typed both spaces but they are combined without code tags.

nilesrex used -n and put a p and the end of the substitute command. This will have the effect of supressing any lines that did not have some spaces to convert. There won't be any lines like that with my version of ls so I used the more simple command.
 
Regexp::Common::delimited(3pm)				User Contributed Perl Documentation			    Regexp::Common::delimited(3pm)

NAME
Regexp::Common::delimited -- provides a regex for delimited strings SYNOPSIS
use Regexp::Common qw /delimited/; while (<>) { /$RE{delimited}{-delim=>'"'}/ and print 'a " delimited string'; /$RE{delimited}{-delim=>'/'}/ and print 'a / delimited string'; } DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface. Do not use this module directly, but load it via Regexp::Common. $RE{delimited}{-delim}{-esc} Returns a pattern that matches a single-character-delimited substring, with optional internal escaping of the delimiter. When "-delim=S" is specified, each character in the sequence S is a possible delimiter. There is no default delimiter, so this flag must always be specified. If "-esc=S" is specified, each character in the sequence S is the delimiter for the corresponding character in the "-delim=S" list. The default escape is backslash. For example: $RE{delimited}{-delim=>'"'} # match "a " delimited string" $RE{delimited}{-delim=>'"'}{-esc=>'"'} # match "a "" delimited string" $RE{delimited}{-delim=>'/'} # match /a / delimited string/ $RE{delimited}{-delim=>q{'"}} # match "string" or 'string' Under "-keep" (See Regexp::Common): $1 captures the entire match $2 captures the opening delimiter (provided only one delimiter was specified) $3 captures delimited portion of the string (provided only one delimiter was specified) $4 captures the closing delimiter (provided only one delimiter was specified) $RE{quoted}{-esc} A synonym for $RE{delimited}{q{-delim='"`}{...}} SEE ALSO
