retrive lines from a file using AWK command
Dear friends,
please tell me how to get some required lines from a file and write to another file using AWK command.
i.e.,
if a file contains,

abcdefghigk
12345
lmnopqrstuv
678910
wxyz


please tell me how to get lines(line count is always 2 and it's contineous) mentioned in blue colour from above file and write the same to another file.

thanks in advance,
swamymns

Are they always the second and third lines of the input file? If so, something like:

Code:
awk 'NR==2 || NR ==3' inputfile > outputfile

Alternatively, if it's always the line matching 12345 and the line after it:

Code:
awk '/12345/ { print ; getline; print }' inputfile > outputfile
