Subject:	Re: Data file access on different path (drive)

Hello,

I tried a very basic script to test this:

#!/bin/bash
ruta_elev="cygdrive/q/geophys/Potential-field datasets/Topography/topo_17.1.img"
ruta_grav="cygdrive/q/geophys/Potential-field datasets/Gravity/grav.img.23.1"
# Also tried
# ruta_elev="Q:/geophys/Potential-field datasets/Topography/topo_17.1.img"
# ruta_grav="Q:/geophys/Potential-field datasets/Gravity/grav.img.23.1"
lon_min=-12
lon_max=0
lat_min=28
lat_max=39
img2grd $ruta_elev  -V -T1 -R$lon_min/$lon_max/$lat_min/$lat_max -S1
-Gelev.grd -m1
img2grd $ruta_grav -T1 -V -R$lon_min/$lon_max/$lat_min/$lat_max -S0.1
-GFA.grd -m1

So pointing to the correct dataset location (from the script location
eg c:/gmt_scripta/test) and it still does not work.

$ bash test4.sh
-12 0 28 39
img2grd: Error for input file: No such file
(Q:/geophys/Potential-field) <- does not recognise the path with space
(or filename) yet can cd to this location - see below!
img2grd: Syntax error: Must specify input imgfile name.
img2grd: Syntax error: More than one world image file name given.
img2grd: Error for input file: No such file (Q:/geophys/Potential-field)
img2grd: Syntax error: Must specify input imgfile name.
img2grd: Syntax error: More than one world image file name given.

Tested cd to directories:

$ cd "cygdrive/q/geophys/Potential-field datasets/Topography"
-bash: cd: cygdrive/q/geophys/Potential-field datasets/Topography: No
such file or directory

$ cd "cygdrive/q/geophys/Potential-field datasets/Topography/"
-bash: cd: cygdrive/q/geophys/Potential-field datasets/Topography/: No
such file or directory

However this works:

$ cd "q:/geophys/Potential-field datasets/Topography/"
$ pwd
/cygdrive/q/geophys/Potential-field datasets/Topography

$ cd "q:/geophys/Potential-field datasets/gravity/"
$ pwd
/cygdrive/q/geophys/Potential-field datasets/gravity

At a loss as to how this works.
