How to remove line if it contains "-" and numbers [0-9]

So if the file is

abcd // no remove because it's has alphabets a-c // no remove because it has numbers 1-1 // remove because it has both number and hyphen a-1 // no remove because it contains alphabet 11 // no remove because it has no hypen

Only remove "1-1" because it contains only numbers and "-"

Try this. This is using perl and regex.

perl -lne '{if($_!~/\d{1,}-\d{1,}/){print $_;}}' input_file

try:

grep -vE "^([0-9]*\\-[0-9]+)|([0-9]+\\-[0-9]*)$" input.txt

or if your input doesn`t contain a line with just "-" character you can simply use:

grep -vE "^[0-9]*\\-[0-9]*$" input.txt
