Hi Viktor and Dominic, If I do the following on Ubuntu 16.04 LTS:
$ echo "1 2" | egrep '[[:digit:]]\s[[:digit:]]’
1 2
… where “1 2” are highlighted in bash
Am I correct that since this POSIX regex for the digits AND the \s is still
being interpreted, my system must support the GNU regex extensions ?
Thanks,
- J
