Using find , you can try:

find . -type f -regex ./test[0-9]\\*.csv.\\* -exec ls -l {} +

Or, using sed , you can try

$ ls -l | sed '/^d/d;/ test[0-9]*\\.csv.*/!d'

(not sure if digits are mandatory -- if they're, then replace * by + )

There are 2 commands in this sed .

1. /^d/d deletes any row that starts with a d (exclude directories)
2. / test[0-9]*\\.csv.*/!d removes any row that doesn't match the regex you want to filter by.
