       procinfo - display system statistics gathered from /proc


       procinfo [ -fdDSbrhv ] [ -nN ]


       procinfo  gathers  some system data from the /proc directory and prints
       it nicely formatted on the standard output device.

       The meanings of the fields are as follows:

              See the man page for free(1)

              The time the system was booted.

       Load average:
              The average number of jobs running, followed by  the  number  of
              runnable  processes  and the total number of processes, followed
              by the PID of the last process run. The pid of the last  running
              process will probably always be procinfo’s PID.

       user:  The amount of time spent running jobs in user space.

       nice:  The amount of time spent running niced jobs in user space.

              The  amount  of  time  spent running in kernel space.  Note: the
              time spent servicing interrupts is not  counted  by  the  kernel
              (and nothing that procinfo can do about it).

       idle:  The amount of time spent doing nothing.

              The time that the system has been up. The above four should more
              or less add up to this one.

       page in:
              The number of disk blocks paged into core from disk. 1 block  is
              equal to 1 kiB.

       page out:
              The  number  of  disk  blocks  paged  out  of core to disk. This
              includes regular disk-writes.

       swap in:
              The number of memory pages paged in from swap.

       swap out:
              The number of memory pages paged out to swap.

              The number of context  switches,  either  since  bootup  or  per

       Disk stats(hda, hdb, sda, sdb):
              The  number  of  reads and writes made to disks, whether CD-ROM,
              hard-drive, or USB.  Shows all disks if they either are  an  hdX
              or sdX, or if they have a non-zero read/write count.

              Number  of  interrupts  serviced  since  boot,  or per interval,
              listed per IRQ.


       -nN    Pause N second between updates. This option implies -f.  It  may
              contain  a decimal point.  The default is 5 seconds. When run by
              root with a pause of 0 seconds, the  program  will  run  at  the
              highest possible priority level.

       -d     For  memory,  CPU  times,  paging,  swapping,  disk, context and
              interrupt stats, display values per second rather  than  totals.
              This option implies -f.

       -D     Same as -d, except that memory stats are displayed as totals.

       -S     When  running with -d or -D, always show values per second, even
              when running with -n N with N greater than one second.

       -b     Display numbers of bytes rather than number of I/O requests.

       -r     This option adds an extra line to the memory info showing ’real’
              free  memory,  just as free(1) does. The numbers produced assume
              that Buffers and Cache are disposable.

       -H     Displays memory stats in ’Human’ (base 1024) numbers (KiB,  MiB,
              GiB), instead of implied KBytes.

       -h     Print a brief help message.

       -v     Print version info.


       When  running  procinfo  fullscreen,  you  can  change its behaviour by
       pressing d, D, S, r and b, which toggle the flags  that  correspond  to
       their  same-named  commandline-options.   In  addition  you can press q
       which quits the program.


       /proc  The proc file system.


       All of these statistics are taken verbatim from the kernel, without any
       scaling.   Any  case where the kernel specifies that a particular field
       means something different from how it is documented in  this  man-page,
       the kernel always wins.

       Some  features  of  the  original  procinfo  were  elided, as they were
       considered non-useful, especially as many of them don’t change anymore,
       and have better utilities for listing/displaying them.


       free(1), uptime(1), w(1), init(8), proc(5).
