Variable not working correctly
On my unix box everytime I use the underbar character "_" I run into trouble
when using it to concatenate two names. The OS reads in the underbar and
looks to the next character, handling it differently.
On one of your replies, someone demonstrated correctly that when you
concatenate, keep the other names plus the underbar character all within
double quotes. That way, the OS will treat the underbar as a literal character instead of (probably) a meta-character.

setuname
setuname(1M) System Administration Commands setuname(1M)
NAME
setuname - change machine information
SYNOPSIS
setuname [-t] [-n node] [-s name]
DESCRIPTION
The setuname utility changes the parameter value for the system name and node name. Each parameter can be changed using setuname and the
appropriate option.
Either or both the -s and -n options must be given when invoking setuname.
The system architecture may place requirements on the size of the system and network node name. The command will issue a fatal warning mes-
sage and an error message if the name entered is incompatible with the system requirements.
OPTIONS
The following options are supported:
-n node Changes the node name. node specifies the new network node name and can consist of alphanumeric characters and the special char-
acters dash, underbar, and dollar sign.
-s name Changes the system name. name specifies new system name and can consist of alphanumeric characters and the special characters
dash, underbar, and dollar sign.
-t Temporary change. No attempt will be made to create a permanent change.

NOTES
setuname attempts to change the parameter values in two places: the running kernel and, as necessary per implementation, to cross system
reboots. A temporary change changes only the running kernel.
