Swap Space

Could someone please explain how you know how much swap space you have on your system. See below:

Code:
# swap -s
total: 8225048k bytes allocated + 4863488k reserved = 13088536k used, 4008032k available

# swap -l
swapfile             dev  swaplo blocks   free
/dev/dsk/c3t0d0s1   32,25     16 4100912 4100912
/data/swap/swap2048m  -       16 4194288 4194288
 
#format
1       swap    wu       0 -   402        1.96GB    (403/0/0)     4100928
 
#df -h

swap                   3.8G   1.0M   3.8G     1%    /etc/svc/volatile
swap                   3.8G   144K   3.8G     1%    /tmp
swap                   3.8G    48K   3.8G     1%    /var/run


admin@sealyaus1 # swap -s
total: 8215744k bytes allocated + 4867656k reserved = 13083400k used, 4013088k available

total: 8215744k bytes allocated - the total amount of swap space, in units of 1024-byte blocks, that is currently allocated as disk-backed swap space.

4867656k reserved - the total amount of swap space, in units of 1024-byte blocks, that is not currently allocated but is claimed by memory for future use.

13083400k used - the total amount of swap space, in units of 1024-byte blocks, that is allocated plus reserved.

4013088k available - the total amount of swap space, in units of 1024-byte blocks that is currently available for future use (ie for reservation and allocation)

The total = 8215744k from swap -s command
using format = 1.96GB
df -h = 3.8GB

Does the total from the 2 swap spaces in the swap -l command equal the df -h value ie
1.96GB + 2048mb, if so where does the rest come from to get total 8215744k

Thanks

NAME
fntsample - PDF and PostScript font samples generator SYNOPSIS
fntsample [ OPTIONS ] -f FONT-FILE -o OUTPUT-FILE fntsample -h DESCRIPTION
fntsample program can be used to generate font samples that show Unicode coverage of the font and are similar in appearance to Unicode charts. Samples can be saved into PDF (default) or PostScript file. OPTIONS
fntsample supports the following options. --font-file, -f FONT-FILE Make samples of FONT-FILE. --font-index, -n IDX Font index for FONT-FILE specified using --font-file option. Useful for files that contain multiple fonts, like TrueType Collec- tions (.ttc). By default font with index 0 is used. --output-file, -o OUTPUT-FILE Write output to OUTPUT-FILE. --other-font-file, -d OTHER-FONT Compare FONT-FILE with OTHER-FONT. Glyphs added to FONT-FILE will be highlighted. --other-index, -m IDX Font index for OTHER-FONT specified using --other-font-file option. --postscript-output, -s Use PostScript format for output instead of PDF. --svg, -g Use SVG format for output. The generated document contains one page. Use range selection options to specify which. --print-outline, -l Print document outlines data to standard output. This data can be used to add outlines (aka bookmarks) to resulting PDF file with pdfoutline program. --include-range, -i RANGE Show characters in RANGE. --exclude-range, -x RANGE Do not show characters in RANGE. --style, -t "STYLE: VAL" Set STYLE to value VAL. Run fntsample with option --help to see list of styles and default values. --help, -h Display help text and exit. Parameter RANGE for -i and -x can be given as one integer or a pair of integers delimited by minus sign (-). Integers can be specified in decimal, hexadecimal (0x...) or octal (0...) format. One integer of a pair can be missing (-N can be used to specify all characters with codes less or equal to N, and N- for all characters with codes greather or equal to N). Multiple -i and -x options can be used. EXAMPLES
Make PDF samples for font.ttf and write them to file samples.pdf: fntsample -f font.ttf -o samples.pdf Make PDF samples for font.ttf, compare it with oldfont.ttf and highlight new glyphs. Write output to file samples.pdf: fntsample -f font.ttf -d oldfont.ttf -o samples.pdf Make PostScript samples for font.ttf and write output to file samples.ps. Show only glyphs for characters with codes less or equal to U+04FF but exclude U+0370-U+03FF: fntsample -f font.ttf -s -o samples.ps -i -0x04FF -x 0x0370-0x03FF Make PDF samples for font.ttf and save output to file samples.pdf adding outlines to it: fntsample -f font.ttf -o temp.pdf -l > outlines.txt pdfoutline temp.pdf outlines.txt samples.pdf AUTHOR
