How can I create multiple file from one?
Like, I have 1.json, but want to create 2.json + 3.json + 4.json out of it.

Most obvious way is to just cp 1.json 2.json and so on; but does Linux provide some way to do it in one command?

You can use a for loop:

for i in {2..4} ; do cp 1.json "$i".json ; done

You can also use tee:

cat 1.json | tee {2,3}.json > 4.json

Instead of using the braces, you can just list the names, too:

for i in 2 3 4 ; do cp 1.json "$i".json ; done

cat 1.json | tee 2.json 3.json > 4.json
