How to output a range of lines from a file?
Easy enough with
sed -n 123,230p filename
This will output filename content, from line 123 to line 230, inclusives. Notice the
p letter after the last line number, this is what instruct
sed to print to stdout.
A tip when working with large files: Add
230p, to prevent
sed to keep scanning until
EOF (end of file). The whole command would then be:
sed -n '123,230p;231q' filename
