I am fairly new to bash and am not sure how to resolve this:
I have a series of geographical long/lat points eg. 50/-30 listed on separate lines in a file called junk2. I have input these into an array and am then using that array in a for loop. Towards the end of the loop I create a file called profile$NUMBER. For each loop I wish to name the profile "profile1" for the first loop, then "profile2" for the second loop, ie. have $NUMBER increase by 1 each time, but how can I do this?
Hi,
I use AIX (ksh) and Linux (bash) servers. I'm trying to do scripts to will run in both ksh and bash, and most of the time it works. But this time I don't get it in bash (I'm more familar in ksh).
The goal of my script if to read a "config file" (like "ini" file), and make various report.... (2 Replies)

Hi,
I have a loop running until a variable L that is read previously in the full script. I'd like to grep some information in an input file at a line that contains the value of the loop parameter $i.
I've tried to use grep, but the problem is nothing is written in the FILE files. It seems grep... (5 Replies)
Hi all! I think someone might be able to solve my problem pretty easily.
I am trying to run a bash loop with 3 variables. I know how to do:
for var1 in `cat list1`; do for var2 in `cat list2`; do for var3 in `cat list3`; command var1 var2 > var3; done; done; done
However, this will run all... (4 Replies)
Dear mentors, I just need little explanation regarding for loop to give input to awk script
for file in `ls *.txt |sort -t"_" -k2n,2`; do
awk script $file
done
which sorts file in order, and will input one after another file in order to awk script
suppose if I have to input 2 or... (4 Replies)
Hello,
I'm trying to read the variable "pause" from a for loop without luck. The function is dependant on the outcome of the test within the loop. If i run this, pause is always 0 within the function. Any ideas?
Thanks.

Hi,

In the below for loop, I extract a variable $d which is an id that will change each time. The bash executes the problem that I am having is that p (after the done) is the path with the extracted $d. However, I can not use it in subsequent loops as it is not reconized. I have been trying to change... (3 Replies)

grdsample
GRDSAMPLE(l) GRDSAMPLE(l)
NAME
grdsample - Resample a grd file onto a new grid
SYNOPSIS
grdsample in_grdfile -Gout_grdfile [ -F ] [ -Idx[m|c][/dy[m|c]] ] [ -Lflag ] [ -Nnx/ny ] [ -Q ] [ -Rwest/east/south/north[r] ] [ -T ] [ -V
]
DESCRIPTION
grdsample reads a grdfile and interpolates it to create a new grdfile with either: a different registration (-T); or, a new grid-spacing
(-I) or number of nodes (-N), and perhaps also a new sub-region (-R). Interpolation is bicubic [Default] or bilinear (-Q) and uses boundary
conditions (-L). Note that using (-R) only is equivalent to grdcut or grdedit -S. grdsample safely creates a fine mesh from a coarse one;
the converse may suffer aliasing unless the data are filtered using grdfft or grdfilter.
in_grdfile
The name of the input 2-D binary grd file.
-G The name of the output grd file.
OPTIONS
No space between the option flag and the associated arguments.
-F Force pixel registration. [Default is grid registration].
-I x_inc [and optionally y_inc] is the grid spacing. Append m to indicate minutes or c to indicate seconds.
-L Boundary condition flag may be x or y or xy indicating data is periodic in range of x or y or both set by -R, or flag may be g indi-
cating geographical conditions (x and y are lon and lat). [Default uses "natural" conditions (second partial derivative normal to
edge is zero).]
-N Specify number of columns nx and rows ny of new grid.
-Q Quick mode, use bilinear rather than bicubic interpolation.
-R west, east, south, and north specify the Region of interest. To specify boundaries in degrees and minutes [and seconds], use the
dd:mm[:ss] format. Append r if lower left and upper right map coordinates are given instead of wesn.
-T Translate between grid and pixel registration while keeping -R and -I the same; if input is grid-registered, output will be pixel-
registered and vice-versa. The input file determines -R, -I and -N so no other options are necessary (except possibly -L or -Q).
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
HINTS
If an interpolation point is not on a node of the input grid, then a NaN at any node in the neighborhood surrounding the point will yield
an interpolated NaN. Bicubic interpolation [default] yields continuous first derivatives but requires a neighborhood of 4 nodes by 4 nodes.
Bilinear interpolation [-Q] uses only a 2 by 2 neighborhood, but yields only zeroth-order continuity. Use bicubic when smoothness is impor-
tant. Use bilinear to minimize the propagation of NaNs.
EXAMPLES
To resample the 5 x 5 minute grid in hawaii_5by5_topo.grd onto a 1 minute grid, try
grdsample hawaii_5by5_topo.grd -I1m -Ghawaii_1by1_topo.grd
To translate the gridline-registered file surface.grd to pixel registration, try
grdsample surface.grd -T -Gpixel.grd
