Yes the problem is the linefeed in the replacement you pass to sed
in the end. You need to reolace the linefeeds read from the "re-
placements1.txt" file by '\\n' for sed to start to like them. One
way to do it would be e.g.
$SHELL --version && sed --version && LINE='echo ---' && $LINE &&
DRAFT='template1.txt' && cat $DRAFT && $LINE && INPUT='replacement1.txt' &&
cat $INPUT && XY=`sed ':a;N;$!ba;s/\n/\\\n/g' $INPUT` && $LINE && LANG=C sed
"s/# placeholder/$XY/" $DRAFT
With
XY=`sed ':a;N;$!ba;s/\n/\\\n/g' $INPUT`
you set XY to the files contents with linefeeds replaced by
'\\n' which is then acceptable to sed.
