I'm having trouble with this one. Maybe it's because I'm running version 11.5.1. Here's what I did:

  1. Created a file named bash.sh in the /shared folder.
  2. Ran the following command: chmod 755 /shared/bash.sh
  3. Ran the following command: bash /shared/bash.sh

The output looked correct, the desired octet was changed:

modify ltm virtual vs-name { destination 10.10.207.x:80 }

But, the actual VS destinations were not changed. Below is the contents of the bash.sh file:

!/bin/bash

tmsh list ltm virtual destination | tr '\n' ' ' \
| sed 's/ \+/ /g;s/ltm virtual/\nmodify ltm virtual/g;s/nation 10\.10\.206/nation 10.10.207/g';echo

the command is meant to generate the commands that can then either be put into a script or run manually. the following should generate a bash script with 'tmsh modify ltm virtual...' commands: echo '!/bin/bash' > /shared/bash2.sh; tmsh list ltm virtual destination | tr '\n' ' ' | sed 's/ \+/ /g;s/ltm virtual/\ntmsh modify ltm virtual/g;s/nation 10\.10\.206/nation 10.10.207/g' >> /shared/bash2.sh; chmod 755 /shared/bash2.sh
