Remove first 15 line

bobo · #1 (**permalink**) 01-27-2006

Friends,

I have a file with 1000 lines. How can I remove the first 15 lines and 20 lines from BOTTOM of the file UP.

Many thanks!

Thank you Vino

What about 20 lines from bottom up. And the files' line-number are randomly come in. sometimes, 850, 900, 700 ....

wc -l filename | awk '{ printf "%d",$1-20'} | xargs -I {} head -{} filename

or

sed -n "1,$(($(wc -l file1 | awk '{print $1'})-20)) p" filename

try the second one in ksh

try the following

ex file_name
:1,5d (specify the range of lines to delete)
:wq!

specify the range correctly to delete the lines.

cheers,
Gaurav

Code:

lines=$((`sed -n '$=' samplefile` - 20)); awk '{ if(NR > 15 && NR < '$lines') print}' samplefile
