Is there an easy way via the command line to truncate them to just the
first five characters (which would be just their ID number)?
This works for me, but is probably overkill:
for file in *; do
new_name=$(echo $file | sed 's/^\([0-9]\{5\}\).*/\1/')
echo Renaming "$file" to "$new_name"
mv -v "$file" "$new_name"
done
You can change the \{5\} to whatever number you want to indicate the
number of digits to capture in a row.
