@Ramesh_srk

Yes Ramesh the directory has a lot of files having xyz* files.

@kshji

Thanks a lot. Its working as expected.

Just wanted to clarify one more thing. There are more than 100 xyz* files present in the directory and I'm checking for only today's file which will be one or two and the others are old files. If I use a for loop will it not take more time?

coz I have search for a lot of different files in different directories created for the day. All these directories will have 100 of files with the same starting charcters as the ones I search for. So if I use a "for" loop wont the script take more time and more CPU utilization. Just wanted to know.

In between your explanation of unix treats the variables and conditions is very helpful. Thanks a ton for that too.

Thanks

uupoll

uuaids(8c)																uuaids(8c)

Name
       uucompact, uumkspool, uurespool, uupoll - uucp utilities

Syntax
       uucompact -ssystem
       uumkspool system ...
       uurespool [ -t# ]
       uupoll system ...

Description
       All of the commands are located in

       The  command  compacts  uucp  system spool directories and associated subdirectories. If system is ALL, then all existing uucp system spool
       directories are compacted.  Otherwise, only the specified system spool directory is compacted.  If no system is	specified,  is	compacted.
       If  is stopped before it is finished, it can be restarted without reprocessing directories.  The command continues processing where it left
       off during it's previous instantiation.

       The command makes a per system spool directory and associated subdirectories for each of the specified systems.	For example, if system	is
       mk3 and if the local system name is penny, the following directories are created:
	       /usr/spool/uucp/sys/mk3
	       /usr/spool/uucp/sys/mk3/C.
	       /usr/spool/uucp/sys/mk3/X.
	       /usr/spool/uucp/sys/mk3/D.
	       /usr/spool/uucp/sys/mk3/D.penny
	       /usr/spool/uucp/sys/mk3/D.penny
       The  command  moves files from old spool directories to	new spool directories.	Because the structure of the spool directories has changed
       from older versions of it is necessary to respool old spooled files to new spool directories in at least two instances:

       o    When installing the current version of

       o    When creating a new system spool directory for each system.

       In the latter case, it is necessary to move files from to the new spool directories.  To ease this task, moves files that have been spooled
       in  one	of 4 formats and respools them under the new spooling structure.  The format is specified by the -t# option, where the number sign
       (#) can be any one of the following:

       o   Original spool - All files are in

       o   Split spool - Contains the subdirectories

       o   Modified split spool -  Contains all subdirectories listed in split spool, and

       o   Used when a new system directory has been created and spool files must be moved from the DEFAULT directory to the new system directory.

       The command forces a connect attempt to the named systems even if recent attempts have failed, but not if the file prohibits the call.  For
       example, the file will prohibit the call if it is the wrong time of day.  Thus, the should be monitored for messages about the connection.
