A problem for sed? Remove parts of a string
Hi,
My knowledge about sed is limited but I have a problem that I think can be solved with sed.

I have a variable in a shell script that stores a lot of path/filenames and the delimitter between them is a space (they all exist on the same line). One part of the filename is the file creation date.
Below an example of how a the variable store three instances of path/filenames:

/logdir/logfile_2008:08:12_Comp.Z /logdir/logfile_2008:08:13_Comp.Z
/logdir/logfile_2008:08:14_Comp.Z

I want to remove all path/filenames that doesn´t match an user specified interval of dates (handled earlier in the script). For example, maybe I have choosed the start date to 2008:08:14. That means that the instances with the dates 2008:08:12 and 2008:08:13 should be removed from the variable and the path/filename with the date 2008:08:14 should be kept in the variable.

How may this be solved with sed (or some other unix tool)?

Thanks,
Rick

amtoc

AMTOC(8)						  System Administration Commands						  AMTOC(8)

NAME

       amtoc - generate TOC (Table Of Contents) for an Amanda run

SYNOPSIS

       amtoc [-a] [-i] [-t] [-f file] [-s subs] [-w] [--] logfile

DESCRIPTION

       Amtoc generates a table of contents for an Amanda run. It's a perl script (if you don't have perl, install it first!).

OPTIONS

       -a
	   The output file name will be label-of-the-tape.toc in the same directory as logfile.

       -i
	   Display help about amtoc.

       -t
	   Generate the output in tabular form.

       -f file
	   Write the output to a file ('-' for stdout).

       -s subs
	   Evaluate the output file name from subs, with $_ set to label-of-the-tape. The -a option is equivalent to -s 's/$_/.toc/'.

       -w
	   Separate tapes with form-feeds and display blank lines before totals.

       --
	   Marks the last option so the next parameter is the logfile.

       logfile
	   (use '-' for stdin)

OUTPUT FORMAT

       The standard output has five fields separated by two spaces:
       #  Server:/partition  date  level  size[Kb]
       0  daily-05:  19991005  -  -
       1  cuisun15:/cuisun15/home  19991005  1	96
       2  cuinfs:/export/dentiste  19991005  1	96
	 ...
       103  cuisg11:/  19991005  0  4139136
       103  total:  -  -  16716288

       In tabular format (-t), this would look like:
	 #  Server:/partition		date	  lev  size[Kb]
	 0  daily-05:			19991005    -	      -
	 1  cuisun15:/cuisun15/home	19991005    1	     96
	 2  cuinfs:/export/dentiste	19991005    1	     96
	 ...
       103  cuisg11:/			19991005    0	4139136
       103  total:			-	    -  16716288

USAGE

       The easiest way to use it is to run amtoc right after amdump in the cron job:
       amdump daily ; logdir=`amgetconf daily logdir` ; log=`ls -1t $logdir/log.*.[0-9] | head -1` ; amtoc -a $log

       which will generate /usr/local/etc/amanda//daily/tape_label.toc. You may also want to call amtoc after an amflush.
