bash : read every line from text file starting at given line number

quadmore · 02-19-2009, 03:57 PM

Hello,

I have a complicated parsing script.

Say my parameter is line number 200. I know my file has more lines than the given parameter.

head -c 200 filename
would give me the first 200 which is not what I need.

What I need is every line starting at line number 200.

I was hoping not to have to nest yet another loop.

TIA for all suggestions,

Bert

sed -n '200,$p' textfile should work.

Note that the $ needs to be escaped or enclosed in single-quotes, or else your shell will interpret $p as if it were a variable.

Code:

tail -n+200 file

will give every line after (including) line 200 in file

Code:

awk 'NR>=200' file

All three solutions work perfectly on my system, I tip my hat to you.

Thank you very much.

Cheers,
