Up until a recent release of grep I could execute this command in
cygwin and it worked without any problems.
echo 20081013193545 | egrep -Eo '[0-9]{1,2}'
This same command still works on other distributions such as centos,
rhel4, rhel5, fedora core 9, etc.
in cygwin:
$ echo 20081013193545 | egrep -Eo '[0-9]{1,2}'
egrep: unknown option -- E
Usage: egrep [OPTION]... PATTERN [FILE]...
Try `egrep --help' for more information.
in other distros:
$ echo 20081013193545 | egrep -Eo '[0-9]{1,2}'
