Selecting a part of a file and copying that into new file in Linux

Question

How can I copy a particular content of a file into a new file using Linux?

For example I have file called test.log file and it contains some 1000 lines. From those 1000 lines I need to copy the lines between 200 - 700 lines.

Is there any single line command in LINUX/UNIX?

Answer 1

试试这个：

sed -n '200,700p' logfilename > destinationFilename

Answer 2

try this line:

awk 'NR>700{exit}NR>=200{print $0 > "newfile"}' yourlog

the line above will stop processing after line 700. it is helpful if your log file is huge.
