In principle they are the same, but one should use ${var} if $var is immediately followed by an alphanumerical character or an underscore (_) . The curly brackets are also necessary if you want to refer to more than nine positional parameters, e.g. ${10)

The /var/adm/messages in Solaris seem to log more system messages/errors compared to /var/log/messages in Linux.
I checked the log level in Linux and they seem OK.
Is there any other log file that contains the messages or is it just that Linux doesn't log great many things? (2 Replies)

Hello, I recently found that my /var/sadm/install/contents, ~/admin/default, /var/spool/patch and /var/spool/pkg files were empty.

modload
MODLOAD(8) BSD System Manager's Manual MODLOAD(8)
NAME
modload -- load a kernel module
SYNOPSIS
modload [-fP] [-b var=boolean] [-i var=integer] [-s var=string] module
modload -p [-b var=boolean] [-d var] [-i var=integer] [-m plist] [-s var=string]
DESCRIPTION
The modload utility loads a kernel module specified by the module parameter into the running system.
Modules are loaded from the default system module areas unless the module parameter contains a path separator character ('/').
The options to modload are as follows:
-b var=boolean Pass the module a boolean property with the name var. boolean may be either true or false.
-d var When used in conjuction with -m, delete var from the plist specified.
-f When a module is loaded, the kernel checks if the module is compatible with the running kernel and will refuse to load mod-
ules that are potentially incompatible. This option disables compatibility checks. Note: an incompatible module can cause
system instability, including data loss or corruption.
This option is also required for re-enabling a builtin module that was disabled using modunload(8).
-i var=integer Pass the module an integer property with the name var and integral value integer.
-m plist When used in conjuction with -p, merge new options with an existing property list contained in plist.
-P This option tells the kernel not to load an associated property list.
-p Output a property list suitable for loading along with a module. When using this option, you do not need to specify a mod-
ule. Use -m and -d to read and modify an existing property list.
-s var=string Pass the module a string property with the name var and string value string.
DIAGNOSTICS
The modload utility exits with a status of 0 on success and with a nonzero status if an error occurs.
SEE ALSO
module(7), modstat(8), modunload(8)
HISTORY
The modload command was designed to be similar in functionality to the corresponding command in SunOS 4.1.3.
