truncate a text file in CLI?

hottdogg · 09-04-2005, 09:46 AM

I'm not a linux expert, sorry for the dumb question.

How to truncate some lines in a file and put the result in created-by-fly new file.

For example, taking only line 43-50 from foo.txt and put the result in bar.txt where bar.txt is created directly in 1 command. Do you know what I mean?

Maybe using piping or redirection or something...I don't know.

Please help. Thx.

Use sed. The command would look something like:

sed -n '43,50p' foo.txt > bar.txt

See:
man sed
