awk 'length >= 300' file

sed -n '/.\{300\}/p' file

[gentoo-user] [OT] find lines in text file by length

This is way OT, but I hope someone here can give me a quick answer:

I have a text-file. Individual lines of it run from 10 to several
thousand characters in length. Is there a simple* command that allows
me to only display the lines that are, say, at least 300 characters
long?

Thanks in advance, 

W


* simple of course includes appropriate incantations of sed/awk/perl/etc

Oh, and obviously

grep '.\{300\}' file

perl -ne 'print if /.{300}/' file

Hi,

Try something like

sed '/\w\{300,\}/!d' file

This should give you lines that have more than 300 word like
characters. If you put number after "," you may define the max number.
and you can change \w to match your needs => . .

Best regards
Petri
