Shell Programming and Scripting

hey everyone.

i was on unix writing a script to rename all my files. and i've been running into problems. i really think this script has potential but i dont know how to get it as to wheres there are no errors. heres basically the steps i used. if some can write the script using the steps i plotted out and tell me where i went wrong in the setup. i would appreciate it. im running sh hopefully ill get into bsh which im more confortable in. check it out thanks


1. Rename a file upon the user’s request. If the file exists, prompt the user for confirmation before renaming the file. The screen should prompt the user for
a. “Name of file you want to rename.” Use the “\c” escape character.
b. “New name of file” Use the “\c” escape character.
c. “File Exist” to avoid overriding a file.
d. “File $oldname changed to $newname”
e. “Do you want to rename another file?” If the user selects “yes” the system should refresh the screen and if the user selects “no” the system should exit to the prompt sign.
f. Refresh the screen to go back to the menu until the user selects the exit option

can you post your script??
