I'm hoping one of you experts out there can help me. I'd like to
delete a file signiture from the top and bottom of a file. I know I
need to use sed, but my sed isn't that good. Could someone please help
me write a sed command. I would appreciate any help.
At the top of the file I have:
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
NotDashEscaped: You need GnuPG to verify this message
And at the bottom I have
-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.5 (GNU/Linux)

=3RVS
-----END PGP SIGNATURE-----
Why use sed? How about:
cat file | head --lines=-3 | awk '{if (/-----BEGIN PGP SIGNATURE-----/)
exit; print $0;}'
The head --lines=-3 prints the file after skipping the first three
lines. The little awk program prints everything until it gets to the
PGP signature line.
Cheers,
Dave
