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 bash script where i need to push some values into an array and when finished, run a for loop against that array for example

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)

grdtrack
GRDTRACK(l) GRDTRACK(l)
NAME
grdtrack - Sampling of a 2-D grdfile along 1-D trackline (a sequence of x,y points)
SYNOPSIS
grdtrack xyfile -Ggrdfile [ -H[nrec] ] [ -L[flag] ] [ -M[flag] ] [ -Q ] [ -Rwest/east/south/north ] [ -S ] [ -V ] [ -Z ] [ -: ] [ -bi[s][n]
] [ -bo[s][n] ]
DESCRIPTION
grdtrack reads a grdfile and a table (from file or standard input) with (x,y) positions in the first two columns (more columns may be
present). It interpolates the grid at the positions in the table and writes out the table with the interpolated values added as a new col-
umn. A bicubic [Default] or bilinear [-Q] interpolation is used, requiring boundary conditions at the limits of the region (see -Lflag
option).
xyfile This is an ASCII [or binary, see -b] file where the first 2 columns hold the (x,y) positions where the user wants to sample the 2-D
data set.
-G grdfile is a 2-D binary grd file with the function f(x,y).
OPTIONS
No space between the option flag and the associated arguments.
-H Input file(s) has Header record(s). Number of header records can be changed by editing your .gmtdefaults file. If used, GMT default
is 1 header record.
-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).] If no flag is supplied, it is assumed that the x column contains longitudes, which may differ from the region in -R
by [multiples of] 360 degrees [Default assumes no periodicity].
-M Multiple segment file. Segment separator is a record beginning with flag. [Default is '>'].
-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.
-S Suppress the output of interpolated points that result in NaN values.
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
-Z Only write out the sampled z-values [Default writes all columns].
-: Toggles between (lon,lat) and (lat,lon) input/output. [Default is (lon,lat)]
-bi Selects binary input. Append s for single precision [Default is double]. Append n for the number of columns in the binary file(s).
[Default is 2 input columns].
-bo Selects binary output. Append s for single precision [Default is double].
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 sample the file hawaii_topo.grd along the SEASAT track track_4.xyg (An ASCII table containing longitude, latitude, and SEASAT-derived
gravity, preceeded by one header record), try
grdtrack track_4.xyg -Ghawaii_topo.grd -H > track_4.xygt
