Sed

[Vanquish]

I want to delete 1st 2 lines and 1st empty space and last empty space in a text file
in a script.

ABCDEFG
-------
AANHITW
ABEAWGI
ABEGIGI

i dont need 1st 2 lines and remove spaces before and after each line.
does
sed -e '/ /d' '1,2,$d' infile >> outfile


Thanks

Try this...

sed -e '1,2d' infile | sed -e 's/^ *//' | sed -e 's/ *$//' > outfile

Probably a way to do it with fewer commands, but that worked for me.

The first part removes the first 2 lines, next remove all whitespace at the beginning of each line, then remove all whitespace at the end of each line. Hope that helps

infile:

ABCDEFG
-------
AANHITW
ABEAWGI (<- 2 whitespaces here)
ABEGIGI

outfile:

AANHITW
ABEAWGI
ABEGIGI

Beginner's luck I suppose. Is there anyway to markup text so its viewed as monospace, something like

 in html? I noticed the presence of the leading whitespace was almost indistinguisable.

Lee, unfortunately not at this time. It has been mentioned a few times, but no joy yet.

If you want, make your suggestion in the 'Forum Issues' thread over in the HPUX/General section. Thats the home for it!
