i would like to write a script in bash to merge two files (file1 file2) in a file 3 line by line from each files. And not with awk I don't really know how to start it. I actually try with head and tail.

so you got a file1 with :

a
b
c

and another file 2 :

1
2
3

so if you execute the script as follow : ./script.sh file1 file2 it print :

a
1
b
2
c
3

Please share sample data and desired results since "Merge" isn't enough information to know what you are trying to do. – JNevill Dec 12 '19 at 19:28

Side by side? Interleaving? – Benjamin W. Dec 12 '19 at 19:32
I did some changes sorry and thanks for your returns @JNevill – YoloSama Dec 12 '19 at 19:35
Are you sure that both files have the same amount of lines? What if one file contains "1 2 3" and the other "a b c d e", should the result be "a 1 b 2 c 3 d e" or should an error message be displayed? – Dominique Dec 12 '19 at 19:36
@Dominique yes that's it ! – YoloSama Dec 12 '19 at 19:37
I wonder what the source of both these files is, and if the problem isn't better solved 'upstream', as it were. – Dec 12 '19 at 19:39
