Hi,
I have a requirement to merge multiple lines based on search pattern. The search criteria is : it will search for CONSTRAINT and when it found CONSTRAINT, it will merge all lines to 1 line till it founds blank line.
For Example:

Hi,
I need help with this-
input.txt :
L B white
X Y white
A B brown
M Y black
Read this input file and if 3rd column is "white", then add specific lines to another file insert.txt.
If 3rd column is brown, add different set of lines to insert.txt, and so on.
For example, the given... (6 Replies)
I have a file in which the data is stored in pairs of lines. The first line (beginining with ">") is a header, the second line is a sequence.
I would like to sort the file by species name. Desired output for the example file:

fb.modes(8) Linux frame buffer utils fb.modes(8)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>
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)
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
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
INTERNALS
Generally a frame buffer display is organized as follows:
+---+---------------+---+---+
| | ^ | | |
| | | 5 | | |
| | v | | |
+---#################---+---+
| # ^ # | |
| # | # | |
| # | # | |
| 1 # | 2 # 3 | 4 |
|<->#<------+------>#<->|<->|
| # | # | |
| # | 6 # | |
| # | # | |
| # v # | |
+---#################---+---+
| | ^ | | |
| | | 7 | | |
| | v | | |
+---+---------------+---+---+
| | ^ | | |
| | | 8 | | |
| | v | | |
+---+---------------+---+---+
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
