Shell script to copy files from one location to another location and rename add the current date to every file

Question

I have a folder in my server which contains some files  These are automated that means everyday we get new files automatically which will overwrite the old ones  So want to take a back up for this data   How can i copy all these files in to a another folder by renaming the files with current date while copying   ex   i have a folder named folder1 which contains 4 files  path for this folder is home webapps project1 folder1   aaa csv bbb csv ccc csv ddd csv   now i want to copy all these four files in to a different folder named folder2  path for this folder is home webapps project1 folder2  while copying these files i want to rename each file and add the current date to the file  so my file names in folder2 should be     aaa091012 csv bbb091012 csv ccc091012 csv ddd091012 csv   I want to write a shell script for this  Please give me some idea or some sample scripts related to this

There is a proper way to split the filename and the extension: Extract filename and extension in Bash

You can apply it like this:

date=$(date +"%m%d%y")
for FILE in folder1/*.csv
do
    bname=$(basename "$FILE")
    extension="${bname##*.}"
    filenamewoext="${bname%.*}"
    newfilename="${filenamewoext}${date}.${extension}
    cp folder1/${FILE} folder2/${newfilename}
done

cp --archive home webapps project1 folder1  aaa bbb ccc ddd  csv home webapps project1 folder2 rename  s   csv     date   m d Y  csv    home webapps project1 folder2  aaa bbb ccc ddd  csv   Explanation    --archive ensures that the files are copied with the same ownership and permissions  foo bar baz  is expanded into foobar foobaz  rename is a commonly available program to do exactly this kind of substitution    PS  don t use ls for this

You could use a script like the below   You would just need to change the date options to match the format you wanted      bin bash  for i in  ls -l  directroy  do cp  i  newDirectory  i  date   m d Y  done
