script to check for a condition inside a file
Hi
I am writing a script file which sends the log files along with their size in a folder named log to a file called temp.log using the following cmd:
ls -st 190_GSTV_HUX_003QISCGSK026** >> /home/user/temp.log

the temp.log looks like this:
16 190_GSTV_HUX_003QISCGSK026_message070321.log
21 190_GSTV_HUX_003QISCGSK026_activity070321.log
10 190_GSTV_HUX_003QISCGSK026_error070321.log

now i need to write a script which checks for the error log file size inside the temp.log
ie., i need to check if the error log file(190_GSTV_HUX_003QISCGSK026_error070321.log) size is zero or not from the file temp.log

is there any cmd to do the same?

any help is greatly appreciated
thanks in advance!!

jfs_fscklog

jfs_fscklog(8)						   Extract/Display JFS fsck Log 					    jfs_fscklog(8)

NAME

       jfs_fscklog - extract a JFS fsck service log into a file and/or format and display the extracted file

SYNOPSIS

       jfs_fscklog [ -d ] [ -e device ] [ -f output.file ] [ -p ] [ -V ]

DESCRIPTION

       jfs_fscklog  with option -e device extracts the contents of either the most recent or immediately prior (specified with option -p) JFS fsck
       service log from the specified device, and writes the output to a file.	The file name may be specified with the -f option, or the  default
       file name is <pwd>fscklog.new.  If the -p option is used, the default file name is <pwd>fscklog.old.

       jfs_fscklog with option -d formats and displays the contents of the extracted file.

       jfs_fscklog with options -d and -e device extracts and displays the JFS fsck service log.

OPTIONS

       -d     Format and display a previously extracted JFS fsck service log.

       -e device
	      Extract  the  JFS fsck service log from device and store it in a file.  (device is the special file name corresponding to the actual
	      device from which the fsck log will be extracted (e.g.  /dev/hdb1 )).

       -f file.name
	      Specify the file name, overriding the default file name.	When used with -e device, file.name specifies the name of  the	file  into
	      which the JFS fsck log will be extracted.  When used with -d, file.name specifies the name of the extracted file whose contents will
	      be formatted and displayed.

	      file.name must be 127 characters or less in length.

	      file.name will be created in the present working directory unless it is fully qualified.

       -p     Extract the prior log (as opposed to the most recent log).

       -V     Print version information and exit (regardless of any other chosen options).

EXAMPLES

	Extract the most recent JFS fsck log on /dev/hda5 into <pwd>fscklog.new:

	      jfs_fscklog -e /dev/hda5

       Extract the most recent JFS fsck log on /dev/hdb3 into /temp/l9651107.log:

	      jfs_fscklog -e /dev/hdb3 -f /temp/l9651107.log

       Display the JFS fsck log that was extracted into /temp/l9651107.log:

	      jfs_fscklog -d -f /temp/l9651107.log

       Extract and display the previous JFS fsck log from /dev/hda8:

	      jfs_fscklog -e /dev/hda8 -d -p
