    WSL and Linux Shell Errors That Delete Data or Block SSH

    How-To Geek’s September 18 guide to “innocent-looking” Linux commands gets the central warning right: a missing character or an unexamined paste can erase a home directory, silently truncate a configuration file, cut off remote administration, or exhaust a machine’s process table.
