Locking a file when using VI to prevent multiple-edit sessions by diff users
At the office, we often have to edit one file with VI. We are 4-6 workers doing it and sometimes can be done at the same time.
We have found a problem and want to prevent it with a file lock. Is it possible and how ?
problem :
Worker-a starts edit VI session on File-A at 1PM
Worker-b starts edit VI session on File-A at 1:05PM
worker-a changes 100 lines and exit/saves at 2:00PM
worker-b changes 1 line and exit/saves at 2:15PM
as result, changes done by worker-a are lost
we even had cases where losts of lines being edited were lost.
if we could lock the file upon editing it with VI, it woud prevent others from editing it and would have to wait for whomever is in to finish before being able to edit it.
