[iphone] I want to search for files and compress them.

file folder test
1.jpeg
10.jpeg
100.jpeg
250.jpeg
1000.jpeg

find . -type f | xargs grep . -e '[0-9]' >test.txt
find . -type f | xargs grep . -e '[0-9]{1,3}' >test.txt
"{}" symbols in regular expressions are not reflected.

find . -name "*" | xargs grep . -e (?test.txt
"[0-9])(?![0-9]): command not found"

It will look like this.

zip: command not found
"zip.wasm" Download this and put it in the test folder.
"*"This doesn't seem reflected.

zip.wasm test.zip "*.jpeg"
zip error; Nothing to do! (test.zip)

Anyway how can I compress a jpeg up to 250 with command?
