BPATCH(1)                    BSD Reference Manual                    BPATCH(1)

NAME
     bpatch - patches a.out files, including kernel and /dev/kmem

SYNOPSIS
     bpatch [-bcwls] [-r] [-N namelist] [-M memfile] location [value]

DESCRIPTION
     The bpatch utility is a quick hack that allows patching of values in
     a.out(5) format files, including kernel or /dev/kmem for the running ker-
     nel.  location is a symbol name, or a decimal/hex/octal number.  value is
     the value to be stored, according to the type options.

     The type options specify the value type to be written:

     -b    Specify value type as 'byte as number'

     -c    Specify value type as 'byte as character'

     -w    Specify value type as 'short/u_short'

     -l    Specify value type as 'long/u_long'

     -s    Specify value type as 'string'

     The -r option indicates that the running kernel is being patched rather
     than a.out.

     The -N namelist option can be used to specify the name of the kernel
     namelist file to be used.  The -M memfile option can be used to specify
     the name of the memory file to be used, this implies -r.
