I think it is still the same.

How about this ?

sed -n -e '/^Q:.*/p' nbu_faq.txt > file1.txt
cp nbu_faq.txt file2.txt


Then look at file1.txt and file2.txt and let me know if that is what you wanted.

This is what I got

Code:
[~/temp]$ cat ny.txt
Q: What is nbu?
A: blablabla...
Q: What is blablabla...?
A: blablabla...
Q: Why ....?
A: blablabla...


[~/temp]$ sed -n -e '/^Q:.*/p' ny.txt
Q: What is nbu?
Q: What is blablabla...?
Q: Why ....?

[~/temp]$ cp ny.txt file.2
[~/temp]$ cat file.2
Q: What is nbu?
A: blablabla...
Q: What is blablabla...?
A: blablabla...
Q: Why ....?
A: blablabla...

X2SYS_MERGE(1gmt)					       Generic Mapping Tools						 X2SYS_MERGE(1gmt)

NAME
x2sys_merge - Merge an updated COEs tables SYNOPSIS
x2sys_merge -Amain_COElist.d -Mnew_COElist.d DESCRIPTION
x2sys_merge will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second file should only contain updated COEs relatively to the first one. That is, it MUST NOT contain any new two tracks intersections (This point is NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had to recompute only the COEs between the edited files and the rest of the database. -A Specify the file main_COElist.d with the main crossover error data base. -M Specify the file new_COElist.d with the newly computed crossover error data base. OPTIONS
No space between the option flag and the associated arguments. EXAMPLES To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt SEE ALSO
x2sys_binlist(1), x2sys_cross(1), x2sys_datalist(1), x2sys_get(1), x2sys_init(1), x2sys_list(1), x2sys_put(1), x2sys_report(1) GMT 4.5.7 15 Jul 2011 X2SYS_MERGE(1gmt)
