First off, i suggest you format the code better. Some errors you made probably because you lost oversight. Once you have debugged your code you might revert it the tightly-packed format which probably saves space (and maybe some small amount of execution time) but until then i suggest you use a more easier-to-read style. Start any "-e" on a separate line, properly (and significantly) indent logical blocks, use empty lines to separate logical blocks, etc..
Code:
# remove name, tripcode and post number nodes that are only for mobile view
-e '$ s_\(<div id="\)pim\([0-9]\{1,25\}\).\{1,1000\}\(\1\(pi\|f\)\2\)_\3_g'
If i get it right you create several groups but only use the third one in the replacement. at least the first can safely be removed, no? You will need the second for the multiplier clause (1-1000), but the nested grouping at the end of the regexp is probably superfluous in parts too. I suppose these are leftovers from developing the regexps.

@bakunin, I decided to use groups again instead. The mobile stuff removal works fine. The first backreference is created to capture the part before the id starting with pim, i.e. the container of mobile stuff.
The second backreference is created to capture the reply's post number. In the third backreference I'm using the first just to make the command shorter and the second one must be there for the command to work on the same reply.
Ok, so then I realised that the line deletion somehow messed up the file and how sed just won't inject the S2, so I turned around 360 degrees, walked away and used egrep/echo for these.
Code:
egrep "^(<!DOCTYPE|<meta |</head>)" $LOC.html > a
head -n2 a > $LOC.html
echo $S2 >> $LOC.html
tail -n1 a >> $LOC.html
rm a
And then I noticed boardBanner"\{0,250\}, that needed to be corrected.
This was a pain in the ass to fix
How do I mark this thread as solved?
