## NAME
       procinfo - display system statistics gathered from /proc


## SYNOPSIS
       **procinfo **[ _-fdDSbrhv_ ] [ _-n_N ]


## 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)](https://www.chedong.com/phpMan.php/man/free/1/markdown)**


### 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 in‐
              terrupts 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
### -n_ -f.  It  may  contain  a  decimal
              **point.  **The default is 5 seconds. When run by root with a pause of 0 seconds, the pro‐
              gram will run at the highest possible priority level.

### -d     
              values per second rather than totals. This option implies **-f.**

### -D      -d, 

### -S      -d  -D,  -n N
              with **N **greater than one second.

### -b     

### -r     
              [free(1)](https://www.chedong.com/phpMan.php/man/free/1/markdown) does. The numbers produced assume that Buffers and Cache are disposable.

### -H     
              plied KBytes.

### -h     

### -v     

## 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, espe‐
       cially as many of them don't change anymore, and have better utilities for listing/displaying
       them.
