sed command issue in script
Hi,

I am using sed command to extract data from my log file for a certain time interval. From and To "time" are my input arguments.
Now if i use the sed command on command line. I get the desired results and If i use it in script.It fails.
sed command as command line:
Code:
sed -n '/04-Mar-2015 12:51:08/,/04-Mar-2015 12:51:52/p' test.log | grep 'fail' >new.log

This one works fine.

In script , I am using
Code:
sed -n '/$FromTime/,/$ToTime/p' $logFile  > new_log.log

and as I input time while running script, I get below error
Code:
user@host> sh log.sh test.log 04-Mar-2015 12:51:08 04-Mar-2015 12:51:52
sed: 0602-419 Cannot find or open file 04-Mar-2015.

Can anyone help me what am i missing in script??I am new to scripting.Any help would be highly appreciated.

log

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

NAME

       log - Records input and output from a program

SYNOPSIS

       /usr/sbin/log <logfile> <command>

OPERANDS

       The file in which to record the interaction being logged.  The command to execute.

DESCRIPTION

       The  log  program  runs <command> and logs the input to and output from <command> to the <logfile> file.  Input and output are logged until
       <command> exits, the log program exits, and the exit status of <command> is returned.

       The log program is used by the system  installation  procedure  and  the  it(8)	command  to  create  the  /var/adm/smlogs/install.log  and
       /var/adm/smlogs/it.log installation log files.

RESTRICTIONS

       Because	the  log  program is used in the installation standalone environment, program size was the greatest concern in its implementation.
       The log program does not search for the PATH variable to locate <command> and error messages are terse.

       The log program causes <command> to take standard input from and write standard output and standard error to  UNIX  pipes.   Some  commands
       will  not  be able to operate in this environment; therefore, it is suggested that you use the script(1) command instead.  UNIX shells will
       not issue prompts when run from log unless the shell is started with an explicit interactive switch (-i for most shells).  For example, log
       foo.tmp /sbin/sh -i

       In the previous example, foo.tmp is the name of <logfile>.

       The  log  program  intercepts  end-of-file (usually Ctrl/d).  Therefore programs which normally receive end-of-file as an exit command must
       exit by some other means.

ERRORS

       Log open error

   Explanation:
       The log program was unable to open <logfile>. Verify that the directory exists and that ownerships and permissions are set correctly.

       Exec Error

   Explanation:
       The log program was unable to execute <command>. Verify that you specified a full pathname for <command> and  that  <command>  is  an  exe-
       cutable file.

       Fork Error

   Explanation:
       The log program was unable to create one of the processes it requires to log data.
