[augeas-devel] Modifying a comma separated list in the postfix main.cf file - possible?

[Graham Leggett]

Hi all,

I have a file /etc/postfix/main.cf that contains the following:

virtual_alias_maps = A, B, C

I want to perform the following three steps:

- Add a value D to the end, producing the following:

virtual_alias_maps = A, B, C, D

- Add a value E to the end, producing the following:

virtual_alias_maps = A, B, C, D, E

- Remove a value D from the comma separated list, producing the following. Notice how we don't know what position D is in the list:

virtual_alias_maps = A, B, C, E

Can this be done with the existing augeas postfix lens today? Does augeas have functionality to manipulate comma separated values, or is the only solution to this problem physically modifying the lens?

Regards,
Graham
