I'm stuck updating some old v2.9.x scripts to work with v3.17 but I can't find a way to clear a defined global variable.
Can anyone post the command(s) necessary to clear an already defined global variable?
I've reviewed the only available documentation (http://wiki.mikrotik.com/wiki/Scripting) but it doesn't even mention clearing global variables.
Cheers
Re: How do you clear a global variable?
By clearing you man delete it? It is not possible, only thing you can do is to set it to nil.

Greetings!
The variables are in
/system script environment
Do a print and then use
remove X
where X is the line number of the variable you want to delete.

Re: How do you clear a global variable?
Thanks for the replies the '/system script enviroment' method works great. I was really getting tired of unneeded global variables.

I use the NO-IP mikrotik scrip, and every now and then, I run this command "/system script environment remove [find user="admin"]" to remove everything, so that I can do a forced IP update
but of course now after a upgrade , the old scripts doesn't work!!!

There is no "user" field in "/system script environment". That is probably why it is not running.

exactly... older versions of ros always said user=admin ... new version...nope
I've changed all the :global to :local ..no more issue's
Re: How do you clear a global variable?
Starting with v6.2 you can unset global variables:
Code: Select all
[admin@pe0] /system> :global aa 1
[admin@pe0] /system> :environment print
aa=1
[admin@pe0] /system> :set aa
[admin@pe0] /system> :environment print
[admin@pe0] /system>

Script to clear all variables
:if ([:len [/system script environment find]] != 0) do={
:for E from=0 to=([:len [/system script environment find]] - 1) do={
/system script environment remove $E
}}
:if ([:len [/system script environment find]] != 0) do={
:for E from=0 to=([:len [/system script environment find]] - 1) do={
/system script environment remove $E
}}
Re: How do you clear a global variable?
Could just use:Script to clear all variables
:if ([:len [/system script environment find]] != 0) do={
:for E from=0 to=([:len [/system script environment find]] - 1) do={
/system script environment remove $E
}}
Code: Select all
/system script environment remove [find]And you can easily make it only delete a variable with a specific name if need be.
Code: Select all
/system script environment remove [find name="ThatVar"]Remember that you need FULL ADMIN permissions to do either of these.
Re: How do you clear a global variable?
Thanks, I was not aware that you can simply add a [find] at the end of the command to remove.Could just use:Script to clear all variables
:if ([:len [/system script environment find]] != 0) do={
:for E from=0 to=([:len [/system script environment find]] - 1) do={
/system script environment remove $E
}}The command doesn't complain if nothing is found.Code: Select all/system script environment remove [find]
And you can easily make it only delete a variable with a specific name if need be.When using WinBox you can also go to "System -> Scripts -> Environment tab" where you have a full list of all global variables and can delete any you you want. You can even change the value of a global variable in this menu.Code: Select all/system script environment remove [find name="ThatVar"]
Remember that you need FULL ADMIN permissions to do either of these.
Re: How do you clear a global variable?
The "[find]" simply selects all objects that matches the search criteria and added them to an array.Thanks, I was not aware that you can simply add a [find] at the end of the command to remove.
If there is more than one object the "remove" command is simply repeated for each object in the array. Same way as if you had done a ":foreach" loop.
