psupdate

NAME

       psupdate - update the ps database of kernel offsets

SYNOPSIS

       psupdate [path to uncompressed kernel image]

DESCRIPTION

       psupdate updates the /etc/psdatabase file to correspond to
       the   current    kernel    image    system    map    file,
       /usr/src/linux/vmlinux by default.

   Options
       If your system map file is not /usr/src/linux/vmlinux, you
       may give the name of an alternate map file on the  command
       line.  This is the only argument currently supported.

FILES

       /etc/psdatabase
       /usr/src/linux/vmlinux

NOTE

       The  database  produced by this version of psupdate is not
       compatible with the one produced by the  kmem-based  psup-
       date.  The procps version does not need some of the things
       contained in the kmemps database, so the  procps  database
       is  slightly  smaller  and has a different "magic" string.
       Also, the kmem-based version (as of v1.2.9) is  not  quite
       as up-to-date in some respects.  If, for some obscure rea-
       son, you want to use both the proc-  and  kmem-based  ver-
       sions  of  the  ps  suites,  you should keep two different
       databases and update both of them at boot (or  kernel-com-
       pilation)  time.   (Please  note  that kmemps, by default,
       puts its database in a different place anyway:  /var/run.)

AUTHORS

       Original code written by Branko Lankaster, horribly munged
       by Michael  K.  Johnson  in  a  desperate  effort  to  add
       /etc/psdatabase  support to procps.  Jeff Uphoff added the
       code to handle ELF-compiled kernels and  rewrote  much  of
       the other code.  Parts of this are still being re-written,
       and the support in ps for alternate namelists  will  hope-
       fully be added soon.
