I have created two scripts, one with hardcoded and another one with extract from file instead of hardcoded,
script:1
--------
#!/bin/ksh
filename="$one/file1.dat"
if [ -f $filename ]
then
echo "$filename has arrived." >> $logfile
else
echo "$filename has NOT yet arrived." >> $logfile
fi
:>
Result:
$one/file1.dat has arrived.
script:2
--------
#!/bin/ksh
outfile=$HOME/outputfile.lst
splitfile=$HOME/splitfile.lst
infile=$HOME/inputfile.lst
rm -f $infile
rm -f $splitfile
rm -f $outfile
sqlplus -s << sqlEOF
$user/$pass
whenever sqlerror exit 1
set head off pages 0
set feedback off
spool $infile
SELECT files
FROM tab1;
spool off
sqlEOF
cat $infile | while read filename time
do
checkfile=$filename
echo $checkfile,$filename >> $splitfile
if [ -f $checkfile ]
then
echo "$checkfile has arrived." >> $logfile
else
echo "$checkfile has NOT yet arrived." >> $logfile
fi
done
Here after execute the script sh script2.sh
1. $infile contains,
$one/file1.dat 101010
$one/file2.dat 110011
$two/file1.lst 090909
$two/file2.lst 110011
2. splitfile shows,
$one/file1.dat,$one/file1.dat
$one/file2.dat,$one/file2.dat
$two/file1.lst,$two/file1.lst
$two/file2.lst,$two/file2.lst
3. outfile shows,
$one/file1.dat has NOT yet arrived.
$one/file2.dat has NOT yet arrived.
$two/file1.lst has NOT yet arrived.
$two/file2.lst has NOT yet arrived.
Here those above files are presents in UNIX directory still it shows NOT yet received and the same is working for script 1 (hardcoded with one single file) and script 2 is NOT working.
Please help me...

DIFF(1) General Commands Manual DIFF(1)
NAME
diff - differential file comparator
SYNOPSIS
diff [ -efbh ] file1 file2
DESCRIPTION
Diff tells what lines must be changed in two files to bring them into agreement. If file1 (file2) is `-', the standard input is used. If
file1 (file2) is a directory, then a file in that directory whose file-name is the same as the file-name of file2 (file1) is used. The
normal output contains lines of these forms:
n1 a n3,n4
n1,n2 d n3
n1,n2 c n3,n4
These lines resemble ed commands to convert file1 into file2. The numbers after the letters pertain to file2. In fact, by exchanging `a'
for `d' and reading backward one may ascertain equally how to convert file2 into file1. As in ed, identical pairs where n1 = n2 or n3 = n4
are abbreviated as a single number.
Following each of these lines come all the lines that are affected in the first file flagged by `<', then all the lines that are affected
in the second file flagged by `>'.
The -b option causes trailing blanks (spaces and tabs) to be ignored and other strings of blanks to compare equal.
The -e option produces a script of a, c and d commands for the editor ed, which will recreate file2 from file1. The -f option produces a
similar script, not useful with ed, in the opposite order. In connection with -e, the following shell program may help maintain multiple
versions of a file. Only an ancestral file ($1) and a chain of version-to-version ed scripts ($2,$3,...) made by diff need be on hand. A
`latest version' appears on the standard output.
(shift; cat $*; echo '1,$p') | ed - $1
Except in rare circumstances, diff finds a smallest sufficient set of file differences.
Option -h does a fast, half-hearted job. It works only when changed stretches are short and well separated, but does work on files of
unlimited length. Options -e and -f are unavailable with -h.
FILES
/tmp/d?????
/usr/lib/diffh for -h
SEE ALSO
cmp(1), comm(1), ed(1)
DIAGNOSTICS
Exit status is 0 for no differences, 1 for some, 2 for trouble.
BUGS
Editing scripts produced under the -e or -f option are naive about creating lines consisting of a single `.'.
