Re: to remove leading and trailing blank lines

Note: blank line => /^$/ i.e., one which has no characters, not even
spaces &/or TABs in it.

sed -e '
# delete all leading blank lines
/./,$!d
/./b
# accumulate a bunch of consecutive blank lines
# then delete that bunch only if u run out of lines.
:a
  $d
  N
/\n\n*$/ba
' yourfile
