Hello
I need to check if following three files exist in a file, how to do that in shell script:
1. ALL MACHING RECORD COLUMNS MATCHED (Baseline and Regression File)
2. Total Mismatched Records (Baseline File): 0
3. Total Mismatched Records (Regression File): 0

Hi,
I have a requirement to search for a string in a large log file along with few lines before and after the the string. The following script was sufficient to search such an entry.
STRING_TO_GREP="$1"
FILE_TO_GREP="$2"
NUMBER_OF_LINES_BEFORE=$3
NUMBER_OF_LINES_AFTER=$4

Hello,
I've searched through the scripting section but could not find what I need.
I need to search for empty sections within a file and remove them.
Here is an example file:
Title 123

Title 098
Title 567

Hi, i would really appreciate any help anyone can give with the following info.
Thanks in advance.
I need to run a search on a file that contains thousands of trades, each trade is added into the file in blocks of 25 lines. i know the search has to take place between a time stamp specified... (4 Replies)
Hi,
I am new to shell scripting and is working on a script to extract lines from a log file between two time stamps using awk command. After some research I used following command:
awk '/01 Oct 2011/{p=1} /10 Oct 2011/{p=0} p' test.log >> tmp.log
This works fine. But now i want to... (3 Replies)
HI group members
I am new in unix
I want to search # symbol in a file.
if found need to delete the entire row in the file.
need to move the actual data(with out # symbol data) to another file.

I have a log file where every line starts with a time stamp. I have to extract lines from the file within a given time stamp.
For example:
IF the file is like this:

Hi,
I want to pull lines between two timestamps from a file. When I just insert values directly it is working fine.
sed -n '/2014-02-14 05:30/,/2014-02-14 05:31/p' Logfile
When I try to insert variable it is not working.
sed -n '/TZ=GMT+1 date +%Y-%m-%d" "%H:%M:%S/,/TZ=GMT date... (2 Replies)

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 | | |

+---+---------------+---+---+
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
