@Kusalananda and those seeing a VTC duplicate to unix.stackexchange.com/questions/432332/â€¦, it sounds to me like they want to remove/delete lines that end in digits, not "remove just the digits"

I still want to know how many digits (s being used twice in the Q/title) are needed at the end to remove the line; 1, or more?

Very simple to do:

awk '/[^0-9]$/ print ' inputfile

Or, if you care to preserve empty lines,

awk '! /[0-9]$/ print ' inputfile

Or in case you are interested in grep too, following simple grep may help also.

grep -v '[0-9]$' Input_file
