[GRASS-dev] g.mlist problem

[William Kyngesburye]

Same happens for me (OSX).  I walked thru the script commands  
manually, and it is indeed messing up on the first sed.

I see this in the sed man for Sed Regex info (OSX uses the BSD sed):

2.   The escape sequence \n matches a newline character embedded in the
      pattern space.  You can't, however, use a literal newline  
character
      in an address or in the substitute command.

Later, for the s/ function, it says:

A line can be split by substituting a newline character into it.
To specify a newline character in the replacement string, precede
it with a backslash.

Putting a real newline after the \ does the trick:

     g.list type=$type mapset=$mapset \
	| grep -v '^-\+$' \
	| grep -v "files available" \
	| grep -vi "mapset" \
	| sed 's/  */\
/g' \
	| grep -v '^$' \
	| grep "$search" \
	| sort \
	| sed -e "s/$/$MAPSET/"
