[SOLVED] Display file from line # to end of file

I know how to display contents at the end of beginning of a file or even at specific lines but how to you display a file from line # to the end of the file?

Thanks & Regards,

Code:

#!/bin/bash

startline=10
cat $1 | perl -nle "print unless $. < $startline"

Thanks.

I just found out this appears to work also:

Code:

sed -n 'line#,$p' file

Where line# is the line you want to start from.

Update: Hmmm. This doesnt work in a bash script as $p gets expanded and errors out. Tried double quotes but no go. :-(

Actually $p would only get expanded in a script if you do use double quotes. Single quotes and it works just fine for me.

Thanks grail but I am using a variable for the line number which is causing me the issue.

Code:

sed -n '$LINES,$p' file

Well that changes things, so like whenever you don't want special stuff to happen, just escape it:

Code:

sed -n "$LINE,\$p" file
