how to bulk update /etc/fstab file

I have about 50 linux servers need updating the records inside /etc/fstab file.

The only change is from those that have netapp:/vol/vol_orabackup mounted to svm2nfs:/vol_orabackup.

The original is netapp:/vol_orabackup /orabackup nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,noac,vers=3,timeo=600

The destination is svm2nfs:/vol_orabackup /orabackup nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,noac,vers=3,timeo=600

Can I write a script and run the script to update it?

I heard about some configuration update tool, is there a tool I can use to manage all configuration files on linux. thank you.

I got the following lines as below, please give your advise:

#!/bin/bash

DIRECTORY=/orabackup2

if [ ! -d "$DIRECTORY" ]; then
  # Control will enter here if $DIRECTORY doesn't exist.
  mkdir /orabackup2
fi


#Create temporary file with new line in place

cat /etc/fstab | sed -e "s/netapp\:\/vol/svm2nfs/" > /tmp/test1

#Copy the new file over the original file

mv /tmp/test1 /etc/fstab

Open in new window
