I have one channel 8 bit raster and when I open it in QGIS with histogram stretching "on the fly" it looks fine. How I can recalculate original raster accordingly changed histogram?

You may use gdalinfo -hist to get histogram data of your image.

Then use the min & max & histogram data to compute the -scale parameter of a gdal_translate command that will stretch your histogram.
