Rename files in bash scripted based on file modified date

Question

It has been awhile since I have had to drive into shell scripting. However, I have a shell script where I'm renaming files based on the file extension from a ftp upload.

Currently, the files are uploaded to the server via an FTP process. All files are renamed from filename.txt to filename.dat. What I would like to do is only rename the files based on the file's modified date after a certain number of minutes.

i.e. all files whose modified time is greater than five (5) minutes.
-mtime -5.

Below is my shell script:

#!/bin/bash
for name in /u/easy/ep2/data/download/*.txt; do
    newname=${name%.txt}.log
    mv "$name" "$newname"
done

Answer 1

You need +5 for more than 5 minutes.

find /u/easy/ep2/data/download -maxdepth 1 -name '*.txt' -mtime +5 \
    -exec sh -c 'mv "$1" "${1%.txt}.log"' arg0ignored {} \;

Edit

Example:

$ find /tmp -maxdepth 1 -name '*.txt' -mtime +5 -exec sh -c 'echo mv "$1" "${1%.txt}.log"' x0 '{}' \;
mv /tmp/1.txt /tmp/1.log
mv /tmp/2.txt /tmp/2.log
