Find big and recently changed files

Goal

The folder testdata holds files of different sizes that were changed at different times. Print two sorted lists of files: first the ones bigger than 1 kilobyte, then a separator line, then the ones changed within the last 2 days.

Example

If testdata held big.log (3 KB, changed last week) and new.txt (10 bytes, changed an hour ago), your script prints:

testdata/big.log
---
testdata/new.txt

Rules

• Edit answer.sh. Search from testdata and list regular files only (-type f).
• Each list is sorted with | sort. The separator is a line containing only --- (echo "---").
• testdata/ is created fresh each time you run the test, so the file times are always current. Run the test once to see the files, then look inside the folder.
• find rounds sizes up to the next whole unit, so a 1,025-byte file counts as 2k.

What you'll practice

find -size and find -mtime.

Run it

gonomicon fetch week-1/02-06-find-by-size-and-age
cd 02-06-find-by-size-and-age
gonomicon test
gonomicon submit

Hints

1. -size +1k means bigger than 1 kilobyte. -mtime -2 means changed less than 2 days ago.
2. Add -type f so only real files show up, not folders.
3. Print the separator with echo "---" and sort each list.
