shell scripting - Write in a file

Question

Shell scripting: I have below input file Contents of file1

-bash-4.2$ cat file1
sample.1.17.10.tar
test.1.17.10.tar
work.1.17.1.0.tar

Need to get output as below

From : > cat file2

    sample
    test
    work

From :>cat file3

1.17.10
1.17.10
1.17.10

It should generate two files by stripping the name and value as mentioned

Are you expecting output of three files above into one file? or you are trying to concat content of all tar files into file or you just need files name? — Sohan

I have input as file1 -> output should be in file2 and file3 — Anusha M

You just need the names? You already have them, they are file2 and file3 surely? — Mark Setchell

Don't you want 1.17.1.0 generated from work.1.17.1.0.tar ? — Walter A
