I Made a Bootable USB Drive for Big Sur. Is there any way to check the version that's installed on the drive before running the install ? Thank you in advance!

With the USB drive connected, from Terminal

hdiutil attach -noverify -nobrowse /Volumes/Install\ macOS\ Big\ Sur/Install\ macOS\ Big\ Sur.app/Contents/SharedSupport/SharedSupport.dmg

open -e  /Volumes/Shared\ Support/com_apple_MobileAsset_MacSoftwareUpdate/com_apple_MobileAsset_MacSoftwareUpdate.xml

Search for <key>OSVersion</key> and <key>Build</key> in the file opened in TextEdit, then

hdiutil detach /Volumes/Shared\ Support/

to detach SharedSupport.dmg

Boot off the stick, from Recovery, go into Disk Utility and select the stick, it should tell you what version of macOS is installed on it.
