Shell Programming and Scripting

Hi! I've a file as shown below

Code:

1 hello
2 how
5 are
3 you
4 hello
5 world

Every statement consists of line numbers at the beginning which are not in sequence.

Now I want to select all the line numbers which are present between the line numbers specified by the user..

For example if the user gives the following input,
starting line number START=2
and ending line number END=4

Then I want all the line numbers which are in between 2 and 4(including START and END) in the given program..
The output has to as shown below

Code:

2
5
3
4

How can I accomplish this??
Thanks in advance..

Code:

$ cat tst
1 hello
2 how
5 are
3 you
4 hello
5 world
$ START=2
$ END=4
$ awk -v s="$START" -v e="$END" '$1==s{f=1}$1==e{print;f=0}f' tst
2 how
5 are
3 you
4 hello
$

If you only need the first column

Code:

$ awk -v s="$START" -v e="$END" '$1==s{f=1}$1==e{print $1;f=0}f{print$1}' tst
