Tricky recursive removal (find with grep)

Tricky one:

I want to do several things all at once to blow away a directory (rm -rf <dir>)

1) I want to find all files recursively that have a specific file extension (.ver) for example.
2) Then in that file, I want to grep for an expression ( "sp2" ) for example.
3) Then I want to blow away only that top level directory that contains that .ver file that contains the "sp2" match (the .ver is nested a few deep)


So for example:

A .ver file might be located here:
./KB981322/update/update.ver

and in that file I find the expression "sp2".


I want to blow away (rm -rf ) the top level directory "/KB981322/"

Other update.ver files may contain the expression "sp3" and I do not want to touch those.

I know how to do a find with grep, but not get the top level directory and pass that to rm -rf.

elf32_fsize(3ELF)					       ELF Library Functions						 elf32_fsize(3ELF)

NAME
elf32_fsize, elf64_fsize - return the size of an object file type SYNOPSIS
cc [ flag ... ] file ... -lelf [ library ... ] #include <libelf.h> size_t elf32_fsize(Elf_Type type, size_t count, unsigned ver); size_t elf64_fsize(Elf_Type type, size_t count, unsigned ver); DESCRIPTION
elf32_fsize() gives the size in bytes of the 32-bit file representation of count data objects with the given type. The library uses version ver to calculate the size. See elf(3ELF) and elf_version(3ELF). Constant values are available for the sizes of fundamental types: Elf_Type File Size Memory Size ELF_T_ADDR ELF32_FSZ_ADDR sizeof(Elf32_Addr) ELF_T_BYTE 1 sizeof(unsigned char) ELF_T_HALF ELF32_FSZ_HALF sizeof(Elf32_Half) ELT_T_OFF ELF32_FSZ_OFF sizeof(Elf32_Off) ELF_T_SWORD ELF32_FSZ_SWORD sizeof(Elf32_Sword) ELF_T_WORD ELF32_FSZ_WORD sizeof(Elf32_Word) elf32_fsize() returns 0 if the value of type or ver is unknown. See elf32_xlatetof(3ELF) for a list of the type values. For the 64-bit class, replace 32 with 64 as appropriate. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Stable | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ SEE ALSO
