How to copy text with ed to new file ?
Alright, so in ed i do a subsititution:

Code:
ed file << 'HERE'
s/.*h2.*>\(.*\)<.*/\1/p
HERE

This gives me my desired line:

Code:
Errors found while checking this document as XHTML 1.0 Transitional!

But how would i put this line in a temporary file ?

It's been so long, does ed search for the right line with just an s, no address?

Good question... it's been so long Smilie

ed on OS X was acting differently to on Linux. I don't know which was correct, so I used g to address the lines, which seemed to agree with both.

Code:
$ cat file1
Some blah
<h2>Errors found while checking this document as XHTML 1.0 Transitional!</h2>
some more blah
<h2>Errors found while checking this document as XHTML 1.0 Transitional!</h2>
even more blah

OS X:
Code:
ed file1 << HERE
1,$ g/<h2>/
s/.*h2.*>\(.*\)<.*/\1/
. w file2
HERE

Output:
Code:
Errors found while checking this document as XHTML 1.0 Transitional!

Code:
ed file1 << HERE
g/<h2>/
1,$ s/.*h2.*>\(.*\)<.*/\1/
. w file2
HERE

Output:
Code:
Errors found while checking this document as XHTML 1.0 Transitional!


CentOS
Code:
ed file1 << HERE
1,$ g/<h2>/
s/.*h2.*>\(.*\)<.*/\1/
. w file2
HERE

Output:
Code:
Errors found while checking this document as XHTML 1.0 Transitional!


Code:
ed file1 << HERE
g/<h2>/
1,$ s/.*h2.*>\(.*\)<.*/\1/
. w file2
HERE

Output:
Code:
even more blah

I thought that this should be enough:
Code:
ed file1 << HERE
1,$ s/.*h2.*>\(.*\)<.*/\1/
. w file2
HERE

which on OS X was correct, but on CentOs was giving the "even more blah" output.

ex seems to work the same on both without g:
Code:
ex file1 << HERE
1,$ s/.*h2.*>\(.*\)<.*/\1/
. w file2
HERE

Output:
Code:
Errors found while checking this document as XHTML 1.0 Transitional!
