Use awk:

Code:

/logdir/logfile_2008:08:13_Comp.Z \
/logdir/logfile_2008:08:14_Comp.Z \
/logdir/logfile_2008:09:01_Comp.Z \
/logdir/logfile_2008:09:14_Comp.Z'

start=20080814
end=20080901
newvar=$(
printf "%s\n" $var |
 awk -F_ -v start=$start -v end=$end '
  {
   date = $2
   gsub( /:/,"",date )
  }
 date >= start && date <= end { printf "%s ", $0 }
'
)

strclean

strclean(8)						      System Manager's Manual						       strclean(8)

NAME

       strclean - Removes outdated STREAMS error log files

SYNOPSIS

       /usr/sbin/strclean [-d logdir] [-a age]

FLAGS

       Specifies  a  maximum  age  in  days for the STREAMS error log files if this not the default age of 3.  The value of age must be an integer
       greater than or less than 3.  Specifies a directory for the location of the STREAMS error log files to  be  removed  if	this  is  not  the
       default directory /var/adm/streams.

DESCRIPTION

       The  strclean  command cleans the STREAMS error logger directory of log files (error.mm-dd) that contain error messages sent by the STREAMS
       log driver (strlog).  If no other directory is specified (the logdir argument), the command removes error log files in the /var/adm/streams
       directory.  If no other age is specified (the age argument), the command removes error log files that have not been modified in 3 days.

       The strclean command is executed by the cron daemon on a periodic basis.

EXAMPLES

       To remove the day-old error log files from a directory called /tmp/streams, enter: strclean -d /tmp/streams -a 1

FILES

       One or more error log file or files on which strclean operates.	The mm.dd in the filename indicates the month and day of the messages con-
       tained in the file.

RELATED INFORMATION

       Commands: strerr(8), cron(8).

       Interfaces: strlog(7).  delim off
