Problem with sed

[Windowed]

Hello,
I have to delete a file any line excepting the lines between x and y. So I use

sed '15, 30 "d '

but I saw that this retrieves the rows in a variable I can use this solution. If someone has a solution to solve my problem, it will be highly appreciated.
Thank you in advance

Hi

but I saw that retrieves the rows in a variable I can use this solution.

With an overview of your code, it would be much more clearer for understanding. Possibly incremented a variable to count the number of rows processed. Please post your complete code and highlight the problem.

Hello
I have posted my code below
Here I retrieves the Max line

mal = $ (grep-n '0000aaaa '$ (i). Tsim.log | sed "s, \:; \ g" | gawk' (print $ 1) '| sed' $! D ')

Here I retrieves the Min line

mil = $ (grep-n 'Tsim> mem' $ (i). Tsim.log | sed "s, \:; \ g")

Then I would delete the entire line that is not in this interval but I do not find a way with sed.

sed '15, 41 "d '$ (i). tsim.log>> $ () BIN_ROM / Plan.txt

Amassing replace my 15 and 41 by my Maxline and Minlin variables if possible. All this his is in a loop.

Hello
I just tested the code and it works fine

/ bin / sh
sed $ 1, $ 2 \! d / etc / rc.d / rc.sysinit
exit 0

We must understand that the shell does not evaluate a variable if it is in single quotes. He estimated that if there is anything or quotes.
