Doesn't works ,
It's because you missed scrutinizer's point.

[0-9]* matches zero or more digits, so it matches the beginning of the line (containing zero digits)
[0-9][0-9]* matches one or more digits

Code:
echo "abce1234jklm" | sed 's/[0-9][0-9]*/ & /'

works as you want

Bipinajith ,
this is nice coding btw, and it too worked for me: Thanks a lot.

Code:
awk '{ match($0,/^[0-9]*/); print substr($0, RSTART, RLENGTH) " " substr($0, RSTART+RLENGTH) } ' file

Can this be used?
Code:
sed 's/[0-9]+/ & /'

This should match minimum one digit?
[0-9]+ gives the same [0-9][0-9]*?

You can with GNU sed en BSD sed -E (extended regex) option...
Code:
sed -E 's/[0-9]+/ & /' file

with regular sed an alternative to the earlier solution would be:
Code:
sed 's/[0-9]\{1,\}/ & /' file
