I have few log files around 100MBs each. Personally I find it cumbersome to deal with such big files. I know that log lines that are interesting to me are only between 200 to 400 lines or so.
What would be a good way to extract relavant log lines from these files ie I just want to pipe the range of line numbers to another file.
For example, the inputs are:
filename: MyHugeLogFile.log
Starting line number: 38438
Ending line number: 39276
Is there a command that I can run in cygwin to cat out only that range in that file? I know that if I can somehow display that range in stdout then I can also pipe to an output file.
Note: Adding Linux tag for more visibility, but I need a solution that might work in cygwin. (Usually linux commands do work in cygwin).
Sounds like a job for sed:
sed -n '8,12p' yourfile
...will send lines 8 through 12 of yourfile to standard out.
If you want to prepend the line number, you may wish to use cat -n first:
cat -n yourfile | sed -n '8,12p'
