Sorting file lines numerically by chromosome?

Question

I have genetic variant data with several columns, currently my variants/lines are in the wrong order and need to be sorted by chromosome. I've tried a few ways to do this using answers from similar questions but none work, mostly giving me empty files.

currently my chromosome order is:

1
10
11
12
13
14
15
16
17
18
19
2
20
21
22
3
4
5
6
7
8
9

these lines need to be sorted in order ascending from 1 to 22.

I've tried:

sort -k 1,1 -k2,2n file.avinput > test.avinput

sortBed -i file.avinput >  test.avinput 

sort -k1,1V -k2,2g file.avinput > test.avinput

bedtools sort -g file.bed> test.avinput #gives *ERROR: Need -i BED file.

These run but when I try head test.avinput it gives me nothing, or when I check with awk '{print $1}' test.avinput | sort -u the order is still wrong - what else can I try to change this?

An example of how a couple lines looks is this:

File.avinput: #3 columns are chromosome, start and end - I have no header

1    10  11
10   200 201
2    20   21
22   2000 2001

Expected ordered output

1    10  11
2    20   21
10   200 201
22   2000 2001

Currently trying any form of using sort -n gives me an empty file.

UPDATED according to changed task.

File file1 with your data created:

$ cat file1
1    10  11
10   200 201
2    20   21
22   2000 2001

Now we sort the file lines and write results to file2:

$ cat file1|sort -n > file2

Or we can even simplify it:

$ sort -n file1 > file2

Checking the results in file2:

$ cat file2
1    10  11
2    20   21
10   200 201
22   2000 2001
