But it looks like the ifcfg-rh module for NetworkManager will use an 
IPV6_TOKEN line, if present, e.g.,

  /etc/sysconfig/network-scripts/ifcfg-ens0:
...
IPV6_TOKEN=::53

myscript '$plusmore' 

should work. note the single quotes.

If you can't use single quotes, I don't know how to use it,, but there
is probably something more arcane that would work, were one a guru.

Have you read thru 'man bash', carefully, looking for informatiion on
quoting?

there is also a document named Advanced Bash Scripting that gives lots
of gory details about doing odd things in Bash that might be helpful.
Google is your friend.

Sounds like you're pretty constrained if you can't escape $plusmore so 
alternatives may not be possible either but, if possible, put the contents 
represented by $plusmore in a file and {read,redirect the output from} the file 
in myscript. Another option might be to put the contents represented by 
$plusmore in an environment variable and access that from myscript.  The only 
other option I can think of is to try a different scripting language (awk, 
perl, tcl, python, you-name-it) to try and get around the issue.

You MUST escape the $ in plusmore. If you don't, the calling shell will
try to expand it, and replace it with whatever is in that variable. If
it's not defined, you'll get an empty string. All this happens *before*
myscript is even called.

I'll add that escaping the $ can be done in other ways. Instead of a
backslash, you can also do:

myscript '$plusmore'

Single quotes prevent variable expansion. However, if you are simply
unable to quote $plusmore in some way, then you're stuck.

Hi Jerry,

The problem is that bu the time you're in your script it's already too late.

myscript   "$plusmore"

basically says take the contents of the environment plusmore and pass that to 
the script.

if you call

myscript   '$plusmore'

you will get what you want.

[CentOS] Simple bash question

[Jerry Geis]

I am calling a bash script and passing in somestring that includes a "$"

myscript   "$plusmore"

I want to assign in the myscript the $1 arg to something like
MYTEXT="$1"

when I do that I dont get what I'm expecting. if I do
MYTEXT='$1'
I still dont get what I'm expecting.

On the first assignment of MYTEXT I do not want the "$" to be treated as a
shell variable. I cannot find out how to do that.

I do not have the option of escaping the call to myscipt "\$plusmore". I
cannot do that.

What am I missing.

[CentOS] NetworkManager and multiple dhcp router option

[Nux!]

Hello,

Our DHCP server broadcasts a router option consisting of 2 IPs.
Ideally they should both be set as default routes with different metrics, 
however this is not what is happening, only the first one gets used.
Anyone has any tips how to convince NetworkManager to do this?

Cheers
