i want to insert the value of datafine.log in a variable.
First, you should notice that funny things ca happen if the content of the file is more than the (probably expected) one line of text. Some caution is advised before you use data in this way therefore.

Aside from these considerations it is quite easy:

Code:
var=$( < /path/to/file )

$( .... ) is a subshell which runs the commands inside the brackets and puts it output on the line, similar to a variable expansion. The command < /path/to/file is a simple redirection which means the output is the content of the file.

I hope this helps.

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
