Above is output from 2.9.5 x86 and mips.

Anyone know how to correctly do compare unequal?

maybe try to left one space between 'comment' and "!=".

Edgars

tried

:foreach i in=[/user find comment !=""] ...
:foreach i in=[/user find comment != ""] ...
:foreach i in=[/user find comment \!= ""] ...

all errored with

no such argument (=)

find command may only check equasions (i.e., whether the value of the given property is equal to something). please use something like that:

:foreach i in=[/interface find] do={:if ([/interface get $i type] != "ether") do={ :put $i}}

thank you for the last reply, confirmed the following works:

:foreach i in=[/user find] do={:if ([/user get $i comment]!="") do=[:put [/user get $i name]]}
