NAME

       procinfo - display system statistics gathered from /proc

SYNOPSIS

       procinfo [ -fdDSbrhv ] [ -nN ]

DESCRIPTION

       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:

       Memory:
              See the man page for free(1)

       Bootup:
              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.

       system:
              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.

       uptime:
              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.

       context:
              The number of context switches, either since bootup or per interval.

       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.

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

OPTIONS

       -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.

INTERACTIVE COMMANDS

       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.

FILES

       /proc  The proc file system.

BUGS

       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.
