Hi David,
awk 'length($0) == 0 && e == 1 { next }
{ e = length($0) == 0 }
{ print }'
results in:
awk: syntax error near line 2
awk: illegal statement near line 2
Oh, line 1. `awk --posix' here suggests length would like parenthesis.
awk '!length() && e {next} {e = !length()} 1'
That didn't help, "awk: syntax error near line 1".
Sigh. Could it be Solaris is *so* old and crufty it has `oawk' in place
as the default awk? Does it have a `nawk' for new awk, IOW the one
matching _The Awk Programming Language_ by Aho, Weinberger, and
Kernighan, 1988? Some 25 years ago?
Apparently, /usr/xpg4/bin/awk is POSIX compliant. Can build and test
instructions for nmh on Solaris not state /usr/xpg4/bin needs to be up
the front of PATH?
I wonder if `diff -b' is the wrong approach as it's applying the -b
to the whole file.
That's OK. mhfixmsg uses an external program to present html, so the
output can have arbitrary spacing. I want to ignore that in the test.
Yep, but that's just on the one line of formatted HTML output; the -b
is causing diff to ignore any other changes introduced elsewhere. :-)
Might not matter, I agree.
Cheers, Ralph.
