Linux UNIX script unable to edit
Hello every one,

I am a newbie , I am trying to run the script .sh file , but when I run this, I need this backup file to store at some location called " /A/B " ,but this location should only consist the latest backup file. which mean at any time this location only consists the latest backup file that is run.
But I am unable to edit the script file as I dont know much about it, Can any one give me your valuable suggestions and how to change the script so that I can have only the latest file at location "/A/B ".

Thanks
Karthik

ls -t lists files ordered by date, you can get the latest that way. Putting its output through head -n 1 will print only the first, i.e. newest, file.
Code:
LATEST_FILE="$(ls -t /A/B | head -n 1 )"

echo "The latest file is ${LATEST_FILE}"
