regex - How do I move files based on a certain character length range? -

i have next files in directory:

f.txt fi.txt fil.txt file.txt filen.txt filena.txt filenam.txt filename.txt filenametoolong.txt

i want move except lastly one. next regular look applies needs: ^.{1,13}.txt

however, using regex with "mv"

mv ^.{1,13}\.txt trashdir

results in

mv: cannot stat `^.1.txt': no such file or directory mv: cannot stat `^.24.txt': no such file or directory

i have checked , double checked regex syntax, , seems valid. missing?

mv command doesn't back upwards regex. can utilize find -regex option:

find . -maxdepth 1 -type f -regex '\./.\{1,13\}' -exec mv {} /trashdir +
