Batch to rename using text file for new name

Issue

I am batch exporting filenames and I have no control over the ouput name of each file. I need to rename each filename to a specific standard. I have created a text file that has the exported filename in one column and what the filename should be renamed to in another column.
Is there a way to write a script that can use the text file to lookup the old name and rename it to the new name?

Solution

You have the old name and new name in two columns in a file. I will call the file "names.txt". Here is the script that will rename all of them in a batch.

var string names ; cat "names.txt" > $names
while ($names <> "")
do
    var str line ; lex "1" $names > $line
    var str oldname, newname ; wex "1" $line > $oldname ; wex "1" $line > $newname
    system rename ("""+$oldname+""") ("""+$newname+""")
done

This script is in biterscripting.

You can download it free from http://www.biterscripting.com . It installs in minutes.

Save the script in file C:Scriptsrename.txt. Start biterscripting. Enter the following command.

script rename.txt

It will rename all the files one by one. Then export them.
