GDAL-INFO(1) GDAL GDAL-INFO(1)
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]
Return information on a dataset (shortcut for 'gdal raster info' or 'gdal vector info').
Positional arguments:
-i, --dataset, --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 = Configuration option [may be repeated]
Options:
-f, --of, --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).
