Ssh Unset Locale Env And Recon Pwd Ls

Unsets common locale and shell environment variables (LANG, LANGUAGE, LC_*, HUMAN_BLOCKS, LS_COLORS) to normalize command output and remove localization artifacts, then performs basic filesystem reconnaissance by executing pwd and ls -la after redundant cd . directory checks. This pattern is commonly used by automated SSH post-authentication scripts to ensure predictable command output across different system locales before enumerating the current working directory contents.
