[gdal-dev] Working with NTF files [SEC=UNCLASSIFIED]

%TEMP% is the Windows environment variable pointing to the temp directory.  For Unix/linux:

,--%<---

# set variable

export GDAL_PAM_PROXY_DIR=/tmp

# confirm

echo $GDAL_PAM_PROXY_DIR

/tmp

Thank you Luke.

1st, that would be

,--%<---

# set variable

export GDAL_PAM_PROXY_DIR=%TEMP%

# confirm

echo $GDAL_PAM_PROXY_DIR

%TEMP%

in the bash-ystems I've used (now working in Funtoo).

2nd, it does not work as expected, see:
