How can I assign awk's variable to shell script's variable?
I have the following script, and I want to assign the output ($10 and $5) from awk to N and L:
output from gridinfo data.grd is: data.grd 50 100 41 82 -2796 6944 0.016 0.016 3001 2461. where N and L is suppose to be 3001 and 100. I use bash shell.
Hi Guys !
I am new to unix and want to find out how we can make sql statement data to shell script variable?
Any help/suggestion is greatly appreciated

:confused: Hi UNIX gurus,
I am facing a typical problem while assigining while assigining output of awk to a variable.
I have a fixed length file say myinputfile.txt
When I allow the value/output of an awk to be redirected to a file, it works fine. i.e.
awk "/^.{232}$acctNum/ {... (8 Replies)
Hi Friends...
Please assist me to assign the result of a SQL query that results two column, to two variables.
Pls find the below code that I write for assigning one column to one variable. and please correct if anything wrong..

Dear All,
we have a command output which looks like :
Total 200 queues in 30000 Kbytes
and we're going to get "200" and "30000" for further process. currently, i'm using :
numA=echo $OUTPUT | awk '{print $2}'
numB=echo $OUTPUT | awk '{print $5}'
my question is : can I use just one... (4 Replies)
How can I assign a variable to an variable. IE $car=honda
One way I can do it is export $car=honda

I have a log file that has certain fields that I want to evaluate, and depending on the value in those fields, I want to put the value of a different field in that line in a particular variable that I'll use later on down the log file. Sort of like setting a switch to change what I do with a bunch... (5 Replies)
I launch 'netstat -a', if string 'ESTABLISHED' found, then VAR=1
#!/bin/bash
VAR=0;
netstat -a | awk '$6 ~ /ESTABLISHED/ {VAR=1}'
I cannot find the right syntax.
thanx guys! (3 Replies)
Hi Gurus,
I have a script which assign awk output to shell variable. current it uses two awk command to assign value to two variables. I want to use one command to assign two values to two variables. I tried the code, but it does't work. kindly provide your suggestion.
current code... (2 Replies)

grdfilter
GRDFILTER(l) GRDFILTER(l)
NAME
grdfilter - Filter a .grd file in the Time domain
SYNOPSIS
grdfilter input_file.grd -Dflag -F<type><width> -Goutput_file.grd [ -Ix_inc[m|c][/y_inc[m|c]] ] [ -Rwest/east/south/north[r] ] [ -T ] [ -V
]
DESCRIPTION
grdfilter will filter a .grd file in the time domain using a boxcar, cosine arch, gaussian, median, or mode filter and computing distances
using Cartesian or Spherical geometries. The output .grd file can optionally be generated as a sub-Region of the input and/or with a new
-Increment. In this way, one may have "extra space" in the input data so that the edges will not be used and the output can be within one-
half- width of the input edges. If the filter is low-pass, then the output may be less frequently sampled than the input.
input_file.grd
The file of points to be filtered.
-D Distance flag tells how grid (x,y) relates to filter width as follows:
flag = 0: grid (x,y) same units as width, Cartesian distances.
flag = 1: grid (x,y) in degrees, width in kilometers, Cartesian distances.
flag = 2: grid (x,y) in degrees, width in km, dx scaled by cos(middle y), Cartesian distances.
The above options are fastest because they allow weight matrix to be computed only once. The next two options are slower because
they recompute weights for each East-West scan line.
flag = 3: grid (x,y) in degrees, width in km, dx scaled by cosine(y), Cartesian distance calculation.
flag = 4: grid (x,y) in degrees, width in km, Spherical distance calculation.
-F Choose one only of bcgmp for (b)oxcar, (c)osine Arch, (g)aussian, (m)edian, or maximum likelihood (p)robability (a mode estimator)
filter and specify full width.
-G output_file.grd is the output of the filter.
OPTIONS -I x_inc [and optionally y_inc] is the output Increment. Append m to indicate minutes, or c to indicate seconds. If the new x_inc,
y_inc are NOT integer multiples of the old ones (in the input data), filtering will be considerably slower. [Default: Same as
input.]
-R west, east, south, and north defines the Region of the output points. [Default: Same as input.]
-T Toggle the node registration for the output grid so as to become the opposite of the input grid [Default gives the same registration
as the input grid].
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
Suppose that north_pacific_dbdb5.grd is a file of 5 minute bathymetry from 140E to 260E and 0N to 50N, and you want to find the medians of
values within a 300km radius (600km full width) of the output points, which you choose to be from 150E to 250E and 10N to 40N, and you want
the output values every 0.5 degree. Using spherical distance calculations, you need:
grdfilter north_pacific_dbdb5.grd -Gfiltered_pacific.grd -Fm600 -D4 -R150/250/10/40 -I0.5 -V
