Hello Helpme

Can I ask what your end goal is? I don't see where variables S1 S2 S3 are defined.

Thanks
P

From original document that's variable will auto generate, i already test if give that variable initialize but that regexp function will exist same bug....

ena cli scrip
set var a "12345:54321:98765"
set var s1 0
set var s2 0
set var s3 0
set var s0 0
set var x $TCL(regexp -all -- {([\d]{1,5}):([\d]*):([\d]{5})} $a s0 s1 s2 s3)

sh var
----------------------------------------
Count : 9
----------------------------------------

------------------------------------------------------------------
variableName variableValue
-------------------------------- --------------------------------
a 12345:54321:98765
CLI.SESSION_TYPE telnet
CLI.USER admin
s0 0
s1 0
s2 0
s3 0
STATUS 0
x 1
------------------------------------------------------------------

The regsub function always only do the match function but variable will not assign ...

so i think that is a bug.

I use ActiveTCL test that above two command the match variable function will ok.

I was trying this out on what is my current version of firmware 15.6.3.1 and it is definitely true that all you can do with regexp is determine if a string matches a pattern. There are no match variable assignments and regsub will do nothing useful.

This is very disappointing because to work around this, an awful lot of extra and quite complex coding is needed. I am going to load up a recent version of XOS and see if anything has changed.

What about using Python instead of CLI scripting?
