After vi is opened, tabe can be used to open multiple files.
I want to finish it in one sentence.
For example, vi a.c.b.c.c. can open three tab pages at the same time.
vi -h | grep tabGet
-p[N] Open N tab pages (default: one for each file)
vi -p4 1.txt 2.txt 3.txt 4.txt
This also line
vi -p 1.txt 2.txt 3.txt 4.txt
Pro-test is feasible:)
