I have a string

joe-dimech-varp123.23-drw.msf
peter-erch-varp2.23-drw.msf
pawlu-donje-seru-varp3123.23-drw.msf

I want to remove the entry containing the varp tag (The varp is followed by a number)

I want to get

joe-dimech-drw.msf
peter-erch--drw.msf
 pawlu-donje-seru-drw.msf

$ sed 's/varp[0-9][^-]*-//' infile
joe-dimech-drw.msf
peter-erch-drw.msf
pawlu-donje-seru-drw.msf

Regards,
Birei
