i have a file acc.sh which has about 10 lines and then i have defined $var which has a line number in it (say 5). i want to extarct from line 5 to the end of the file and put the output into another file. I have used
sed -n $var,'$p' acc.sh | tee abc.sh

sed: -e expression #1, char 1: unknown command: `,'

use > not |
Code:
sed "$var,\$ p" acc.sh > abc.sh
