Well, regexp syntax is different to shell glob syntax.
In the shell, * means "0 or more characters".
In a regexp, * means "0 or more of the preceeding item" and is thus
illegal at the start of a regexp (no preceeding item there) - forgiving
programs may well treat it as a literal * there.
Try this
ps ax | grep -i real
With grep the regexp does not need to match the whole line.
Also bear in mind that the ps command is ofteni, um, overly helpful -
it will crop long lines rather than display them. By including the "u"
option you may be cropping enough stuff to remove "realplay" from the
listing. Maybe.
