In a number of places in the linux scripts, there is a sequence like the following. This requires write access to the current directory. wget ... http://...../somefile.php rm somefile.php That could be better replaced with this sequence: (at the top of the file) OA_WGET_OUTPUT=/dev/null (down below) wget -O $OA_WGET_OUTPUT ... http://...../somefile.php Two advantages: - Since the output is never written to a file, there is no problem with a read-only directory. - for debugging, you can easily redirect the output either to stdout or to a real file, just by changing OA_WGET_OUTPUT. Note: to send output to stdout, use a minus sign as the file name: OA_WGET_OUTPUT=- |
