日16岁少女偶像自杀原因成谜 曾问过这样一句话少女偶像自杀

OneOn some systems, such as [[Unix-like]] systems or Windows, one can modify the set of available commands by modifying which paths appear in the [[PATH (variable)|PATH]] environment variable or its equivalent. UnderOn Unix-like systems, commands also need be marked as [[executable]] files. The directories in the path variable are searched in the order they are given. By re-ordering the path, one can run e.g. \OS2\MDOS\E.EXE instead of \OS2\E.EXE, when the default is the opposite. Renaming of the executables also works: people often rename their favourite editor to EDIT, for example.

The command line allows one to restrict available commands, such as access to advanced internal commands. The [[Bourne shell]] and workalikes such as [[Bash (Unix shell)|Bash]] can be run as a [[restricted shell]]; among other things, this prohibits the user from modifying the PATH environment variable, so that if PATH is set to include only directories that contain only permissible commands, the user will only be able to run those commands. The Windows [[CMD.EXE]] doesalso thissupports restricting available commands. Often, shareware programs will limit the range of commands, including printing a command 'your administrator has disabled running batch files' from the prompt.{{Clarify|reason=The sentence seems ambigious and confuses me. Does "including printing a command 'your administrator has disabled running batch files' from the prompt" describe an act of limiting the range of commands, or does it rather describe a command that a user may (try to) give which is then limited?|date=July 2021}}
