Shell Programming and Scripting

Hey,

Can someone pls give me an idea on how to write a shell script for the below requirement.

I am generating lot of .txt files in a unix directory through a etl tool, now I need to write a shell script which will move these files to another directory(\abc\xyz\source), but in the \abc\xyz\source same file may exsit , if the file with the same name is exsiting then I need to remove the exsiting file file and replace those files with the newly created file from the ETL tool.

Example:- In my source dir I have the below files.
1.txt
2.txt
3.txt

and in the target directory I have

4.txt
5.txt
3.txt
1.txt

Now I want the shell script to move all the files from source dir and replace the files in the target directory, this replace should happen for only those files which are exsiting in the source dir.so my output should be as below.

1.txt
2.txt -- this should be replaced, i.e existing file should be removed and new file should be placed here.
3.txt -- this should be replaced, i.e existing file should be removed and new file should be placed here.
4.txt
5.txt

Thx,

just use mv with -f option (do not prompt before overwriting)

Code:

$ mv -f /abc/xyz/source/* /abc/xyz/target/

Hey Thanks a lot.., I was thinking all the other ways except the mv -f.


Once again Thanks a lot.

Thx,
Shruthi
