check if directory and file exists
Code:
cp $PATHLOGS/$DATE/*.* $TMP/logs_tmp/
cp $PATHLOGS/$DATE1/*.* $TMP/logs_tmp/



Before copying the files I have to check if the directory $DATE1 and $DATE2 exists.
If directory exists then, check if the folder contains some files.
if the file exists then, check if the file size is greater than 0.

If any of the above condition doesn't satisfy in the above directory, I have should stop the script executing.

shtool-tarball

SHTOOL-TARBALL.TMP(1)					      GNU Portable Shell Tool					     SHTOOL-TARBALL.TMP(1)

NAME

       shtool-tarball - GNU shtool command for rolling standardized tarballs

SYNOPSIS

       shtool tarball [-t|--trace] [-v|--verbose] [-o|--output tarball] [-c|--compress prog] [-d|--directory directory] [-u|--user user]
       [-g|--group group] [-e|--exclude pattern] path [path ...]

DESCRIPTION

       This command is for rolling input files under path into a distribution tarballs which can be extracted by tar(1).

       The four important aspects of good open source software tarballs are: (1) unpack into a single top-level directory, (2) top-level directory
       corresponds to the tarball filename, (3) tarball files should be sorted and (4) arbitrary names for file owner and group.

OPTIONS

       The following command line options are available.

       -v, --verbose
	   Display some processing information.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

       -o, --output tarball
	   Output tarball to file tarball.

       -c, --compress prog
	   Pipe resulting tarball through compression program prog.

       -d, --directory directory
	   Sets the top-level directory into which the tarball unpacks.  By default it is tarball without the trailing ".tar.*" extension.

       -u, --user user
	   The user (owner) of files and directories in the tarball to user.

       -g, --group group
	   The group of files and directories in the tarball to group.

       -e, --exclude pattern
	   Exclude files and directories matching comma-separated list of regex pattern from the tarball. Directories are expanded before the
	   filtering takes place. The default filter pattern is ""CVS,\.cvsignore,\.svn,\.[oa]$"".

EXAMPLE

	#   Makefile.in
	dist:
	    ...
	    V=`shtool version -d short ...`; 
	    shtool tarball -o foobar-$$V.tar.gz -c 'gzip -9' 
			   -u bar -g gnu -e 'CVS,.cvsignore' .

HISTORY

       The GNU shtool tarball command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1999 for GNU shtool.

SEE ALSO

       shtool(1), tar(1), compress(1).
