I don't know what you mean by "only 1235". Do you mean with no leading or
trailing digits? I.e. A1235B is a match, but 01235 is not. Or do you mean
"a line which contains _only_ 1235 and no other characters?
For the first, this should work: egrep
'(^|[^[:digit:]])1235($|[^[:digit:]])'
({^|[^[:digit:])) matches the beginning of the ​string (^) or a non-digit
[^[:digit:]]
then the digits "1235
($|[^[:digit:]]) then matches the end of the string ($) or a non-digit.
Oh, what does this have to do with BASH????? And how is it a bug? IOW, this
looks like the wrong forum. This is not a general UNIX (or Linux) question
