Help with calculating frequency of specific word in a string
Input file:
Desired output file:
Perl script that I have tried:
Command I have tried:
My purpose is to calculate the frequency of "Z" at each string in detail.
However, I only able to total sum all the frequency of "Z" in each string.
Hello,
I require a perl script that will read a .txt file that contains words like
224.199.207.IN-ADDR.ARPA. IN NS NS1.internet.com.
4.200.162.207.in-addr.arpa. IN PTR beeriftw.internet.com.
arroyoeinternet.com. IN A 200.199.227.49
I want to focus on words:

Hi All ,
I have different strings (SQL queries infact) of different lengths such as:
1. "SELECT XYZ FROM ABC WHERE ABC.DEF='123' "
2. "DELETE FROM ABC WHERE ABC.DEF='567'"
3. "SELECT * FROM ABC"
I need to find out the word coming after the... (1 Reply)
Hi,
I have a file containing the frequency's of an element sorted in ascending order. The file looks something like this:

Hello,
I'm almost there with scripting, and I've looked at a few examples that could help me out here. But I'm still at a lost where to start. I'm looking to parse each line in the log file below and save the output like below.

fb.modes(5) Linux frame buffer utils fb.modes(5)NAME
fb.modes - frame buffer modes file
DESCRIPTION
/etc/fb.modes contains an unlimited number of video mode descriptions. The general format of a video mode is:
mode
geometry <xres> <yres> <vxres> <vyres> <depth>
timings <pixclock> <left> <right> <upper> <lower> <hslen> <vslen>
options <value>
rgba <red,green,blue,alpha>
endmode
OPTIONS
geometry options:
xres visible horizontal resolution (in pixels)
yres visible vertical resolution (in pixels)
vxres virtual horizontal resolution (in pixels)
vyres virtual vertical resolution (in pixels)
depth display depth (in bits per pixel)
timing options:
pixclock
length of one pixel (in picoseconds)
left left margin (in pixels)
right right margin (in pixels)
upper upper margin (in pixel lines)
lower lower margin (in pixel lines)
hslen horizontal sync length (in pixels)
vslen vertical sync length (in pixel lines)
rgba options (only valid with truecolor):
red red color bitfields (in length or length/offset)
green green color bitfields (in length or length/offset)
blue blue color bitfields (in length or length/offset)
alpha alpha color bitfields (in length or length/offset)
other options:
the first value of this options is the default
hsync {low|high}
the horizontal sync polarity
vsync {low|high}
the vertical sync polarity
csync {low|high}
the composite sync polarity
gsync {low|high}
the sync on green polarity
bcast {false|true}
enable or disable broadcast modes. If enabled the frame buffer generates the exact timings fot several broadcast modes (e.g.
PAL or NTSC). Note that this option may not be supported by every frame buffer
extsync {false|true}
enable or disable external resync. If enabled the sync timings are not generated by the frame buffer device and must be pro-
vided externally instead. Note that this option may not be supported by every frame buffer device
laced {false|true}
enable or disable interlace. If enabled the display will be split in two frames, each frame contains only even and odd lines
respectively. These two frames will be displayed alternating, this way twice the lines can be displayed and the vertical fre-
quency for monitor stays the same, but the visible vertical frequency gets halved
double {false|true}
enable or disable doublescan. If enabled every line will be displayed twice and this way the horizontal frequency can easily
be doubled, so that the same resolution can be displayed on different monitors, even if the horizontal frequency specifica-
tion differs. Note that this option may not be supported by every frame buffer device
nostd <number>
select nonstandard video mode
accel {false|true}
enable or disable hardware text acceleration
grayscale {false|true}
enable or disable graylevels instead of colors
INTERNALS
Generally a frame buffer display is organized as follows:
+---+---------------+---+---+
| | ^ | | |
| | | 5 | | |
| | v | | |
+---#################---+---+
| # ^ # | |
| # | # | |
| # | # | |
| 1 # | 2 # 3 | 4 |
|<->#<------+------>#<->|<->|
| # | # | |
| # | 6 # | |
| # | # | |
| # v # | |
+---#################---+---+
| | ^ | | |

| | v | | |
+---+---------------+---+---+
| | ^ | | |
| | | 8 | | |

+---+---------------+---+---+
1 left margin
2 xres
3 right margin
4 horizontal sync len
5 upper margin
6 yres
7 lower margin
8 vertical sync len
The area bordered with `#' is the visible display area. Horizontal and vertical frequencies can now easily be calculated, for this the sum
of horizontal or vertical values are important
htotal = left + xres + right + hslen
vtotal = upper + yres + lower + vslen
The length of one line can now be calculated with pixclock
line = pixclock * htotal
and we have the horizontal frequency
hfreq = 1E12 / line = 1E12 / (pixclock * htotal)
To get the vertical frequency vtotal must eventually adjusted. If the display is laced, vtotal must be halved or if the display is a dou-
blescan one, vtotal must be doubled. Now we can calculate the length of one frame
if (lace) vtotal /= 2
if (double) vtotal *= 2
frame = vtotal * line
and we get also the vertical frequency
vfreq = 1E12 / frame = hfreq / vtotal
