MySQL grep,egrep,fgrep

gerp Search a Pa tern from current directory.

egrep (grep -E in linux) is extended grep where additional regular expression metacharacters have been added like +, ?, | and ().

fgrep (grep -F in linux) is fixed or fast grep and behaves as grep but does not recognise any regular expression metacharacters as being special.
