filenames - How to use wildcard in the middle on the string? bash -

i writing bash script

my files like: file="${nodeid}_00000_19700101010${ts}_udp_filtered.pcap". possible instead of 00000 utilize 5digit number? thought using

file="${nodeid}_*_19700101010${ts}_udp_filtered.pcap"

sometimes have 00001, 00004, etc.

something like

echo "${nodeid}"_[0-9][0-9][0-9][0-9][0-9]_19700101010"${ts}"_udp_filtered.pcap

note, * , [something] won't expand in quotes, variables quoted above.
