نام (NAME)
gdal-info - دریافت اطلاعات یک مجموعه‌داده
در نسخه 3.11 اضافه شد.
بسته به ماهیت مجموعه‌داده مشخص‌شده، به عنوان یک میانبر برای gdal raster info یا gdal vector info عمل می‌کند.
خلاصه دستور (SYNOPSIS)
Usage: gdal info [OPTIONS] <INPUT> Return information on a dataset (shortcut for 'gdal raster info' or 'gdal vector info'). Positional arguments: -i, --dataset, --input <INPUT> Input raster, vector or multidimensional raster dataset [required] Common Options: -h, --help Display help message and exit --json-usage Display usage as JSON document and exit --config <KEY>=<VALUE> Configuration option [may be repeated] Options: -f, --of, --format, --output-format <OUTPUT-FORMAT> Output format. OUTPUT-FORMAT=json|text For all options, run 'gdal raster info --help' or 'gdal vector info --help'
وضعیت خروج (EXIT STATUS)
این برنامه در صورت موفقیت کد وضعیت 0، و در صورت بروز خطا مقدار غیر صفر را برمی‌گرداند (خطاهای غیرمسدودکننده که به عنوان هشدار صادر می‌شوند، به منزله اجرای موفقیت‌آمیز در نظر گرفته می‌شوند).
مثال‌ها (EXAMPLES)
مثال ۱: دریافت اطلاعات فایل utmsmall.tif (با خروجی متنی)
