shell - Regex: Find files not ending with numeral suffix -

i need make command returns files without numeral suffix (*.0, *.123, ...)

have example 3 files:

gg.p  qqq.449  rtr55

i want find these:

./rtr55 ./gg.p

i tried find them using grep. got results no effect.

find -type f | grep -v '\.[0-9]+$'

(this command returned:)

./qqq.449 ./rtr55 ./gg.p

so there regex format error. know, how fix it?

the + operator belongs extended regular expressions. there many workarounds:

find -type f | grep -v '\.[0-9]\+$' find -type f | egrep -v '\.[0-9]+$' find -type f | grep -e -v '\.[0-9]+$' find -type f | grep -v '\.[0-9][0-9]*$'
