<BR>
Actually this is not needed (and there was not a real reason for -<BR>
input_file_list to exist in gdalbuildvrt too). All GDAL/OGR utilities have a<BR>
"--optfile filename" (note the double dash before optfile) option that uses the<BR>
lines of filename as arguments of the utility.<BR>
<BR>
See :<BR>
<BR>
$ gdalinfo --help-general<BR>
Generic GDAL utility command options:<BR>
--version: report version of GDAL in use.<BR>
--license: report GDAL license info.<BR>
--formats: report all configured format drivers.<BR>
--format [format]: details of one format.<BR>
--optfile filename: expand an option file into the argument list.<BR>
--config key value: set system configuration option.<BR>
--debug [on/off/value]: set debug level.<BR>
--pause: wait for user input, time to attach debugger<BR>
--locale [locale]: install locale for debugging (ie. en_US.UTF-8)<BR>
--help-general: report detailed help on general options.<BR>
<BR>
<BR>
So you should be able to run :<BR>
<BR>
gdalwarp --optfile text_file_with_src_files.txt target.tif<BR>
