Define current date? The same as today's date, or less than 24 hours old? Does the file have a specific name or is there more than one or different? Any limitation on which shell (bash, bourne, perl, etc.)

Suppose there is one file    ABC_08082014.txt  present in one folder.
Folder contains  2 files ... one for current day and other for yesterday.
ABC_07082014.txt   --- yesterday file
ABC_08082014.txt

So my requirements is check the todays file is present or not.
If todays file is not preasent then create the todays file.
If file is present then give the error message that file is already created.

Need Unix shell script.

Here ya go...

Of course you will have to change new/ to the path of your directory, and this will also just create an empty txt file with todays date.

#!/bin/bash
TD=`date +%d%m%Y`
CHECK=`find new/ -type f -mtime -1 | grep -oh $TD`

if [ "$TD" = "$CHECK" ]; then
	echo "FILE EXISTS"
else
	echo "TODAYS FILE DOES NOT EXIST"
	echo "Creating todays file.."
	touch "new/ABC_$TD.txt"
fi

Assuming the filenames use the date format you showed, then do

#!/bin/bash
TODAY=$(date +%d%m%Y)

cd /to/your/folder

if [ -f ABC_$TODAY.txt ]
then
      echo "File already exists for today"
else
     touch ABC_$TODAY.txt
fi
