adding entries to a /etc/export file

[GUVNIJJAR]

I need advise on how you would amend entries on a /etc/exports file via command line.   When i had an entry via using the exportfs -p, it overrides my entry, such as i have added the below entry :

exportfs -p rw=10.25.4.151:10.25.4.150:10.24.152:10.25.4.161:10.25.4.162:10.25.4.163,root=10.25.4.151:10.25.4.150:10.25.4.152:10.25.4.161:10.25.4.162:102.25.4.163

I Know want to remove the ip address 102.25.4.163 from the root access, and add an IP 10.25.4.163.   How can i write this without writing the whole command again.

Also after adding, do i need to run the exportfs -a command .

You can't. You will have to use some external processing to extract information, change it and replace the line again.

And yes, if you changed just /etc/exports, you will need to run "exportfs -a" (or just for this entry) to activate it.
