${var} is usefull when you want to include the variable in some echo output (in shell, in perl it can be print), that needs to be followed immediately by some string. Here is an example:
This wont work:
Code:
echo "$varsomething"

But this will:
Code:
echo "${var}something"

So basically saying, {} are indicating borders of variable's name.

/var/adm/messages vs /var/log/messages

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)

SCROLLKEEPER-REBUILDDB(8)				      System Manager's Manual					 SCROLLKEEPER-REBUILDDB(8)

NAME

       scrollkeeper-rebuilddb - rebuild the scrollkeeper document catalog database

SYNOPSIS

       scrollkeeper-rebuilddb [-p path ] [-v] [-q]

DESCRIPTION

       This rebuilds the ScrollKeeper database from the original OMF metadata files and documents.  Under normal situations, this tool is not nec-
       essary.	It is useful however if the database becomes corrupt, which could be caused by interruption of ScrollKeeper during  an	update	of
       the database.

       Errors and warnings are logged to /var/log/scrollkeeper.log.

OPTIONS

       -p path
	      Use path as the ScrollKeeper database directory.

       -v     Verbose.	Show warnings and error messages in addition to logging them to /var/log/scrollkeeper.log.

       -q     Run  in  quiet  mode, suppressing output of all but the most serious warning and error messages to STDOUT.  Note that most output to
	      the log file will be unchanged.

FILES

       /var/lib/scrollkeeper/scrollkeeper_docs
       /var/lib/scrollkeeper/TOC/<docnumber>
       /var/lib/scrollkeeper/<locale>/scrollkeeper_cl.xml
       /var/lib/scrollkeeper/<locale>/scrollkeeper_extended_cl.xml
       /var/log/scrollkeeper.log
