Solution 1

Try the following regular expression

PERL

[^a-zA-Z0-9]+

The example follows

echo "abc---012" | sed -e 's/[^0-9a-zA-Z][^0-9a-zA-Z]*/ /g'
#output
abc 012

FYI: .+ is equivalent to ..*

PERL

[^a-zA-Z0-9]

example follows

echo "abc---012" | sed -e 's/[^0-9a-zA-Z]/ /g'
#output
abc   012
