hello.I am new to this site.Infact first timer. :)

I am creating a file "xyz.txt" in unix.Saving some values in it.
This whole thing is in a script,and i need to run the script several times.
Each time the script runs i want it to overwrite the previous content.

Any help regarding this will be truly appreciated.

Each time you execute your script, the file should be overwritten unless the "xyz.txt" file was created with only read permission for the owner.

As a beginner, you probably have questions about file permissions, ownership, and the chmod command. This link is probably as good as the thousands of links on the web:


Let me know if you have any further questions.
