Hello,Here is the example:??
??file name? ? first row??file1.txt? ? ?abc.txt??file2.txt? ?
?bed.txt??file3.txt? ? ?gogo.txt??.?.?file1243.txt? ? last.txt????
I want to use loop because I need to read the first row information for first
file, and then rename the file, then go to next file. I'm not sure if this
is right way to approach my goal. Any suggestion will be
appreciated.?Thanks,?Kai    On Friday, September 16, 2022 at 10:38:32 AM PDT,

 Hello,

Please post the first row of 2 or 3 files and the expected result.

You can rename files with ?file.rename. This function is vectorized its
on arguments so you do not need a loop, only the source and destination
filenames. Both vectors should have the same length, if not strange
things will occur including data loss.

Hope this helps,
