	The //SCP/Shell page// on the [[ui_login_advanced\|Advanced Site Settings dialog]] allows user to configure shell specific options. Mostly it helps WinSCP to modify remote environment to match its [[requirements#scp\|requirements]]. The options are mainly used when working with [[scp\|SCP protocol]]. Even if you are using [[sftp\|SFTP protocol]], some of the options are made available for you, in case you are using some feature that require [[shell_session\|separate shell session]]. ((When [[ui_login_sftp#protocol_options\|fallback]] to [[scp\|SCP protocol]] occurs, all options on the page, including the disabled ones, are used.

	On start-up WinSCP will by default clear all aliases on commands it uses. This is done to avoid unexpected behavior (e.g. alias ''rm'' to ''rm -i''). If there are no aliases influencing command behavior, this feature can be disabled by unticking //Clear aliases//. This setting speeds up the login process.

-	WinSCP also clears set of environment variables know to influence the format of directory listing. These are: ''LANG'', ''LANGUAGE'', ''LC_CTYPE'', ''LC_COLLATE'', ''LC_MONETARY'', ''LC_NUMERIC'', ''LC_TIME'', ''LC_MESSAGES'' and ''LC_ALL''. If no such variable is set, untick //Clear national variables//.

	WinSCP uses ''scp'' command to perform the transfer. On some SSH servers, particularly ssh.com, the ''scp'' may be a link to ''scp2'' command. The ''scp2'' is in fact SFTP server, that WinSCP cannot talk to in SCP mode. Check //Use scp2 with scp1 compat.// to make WinSCP try to force the ''scp'' command to use really the SCP protocol (using ''-1'' option). Note that if the server supports ''scp2'', it probably supports [[sftp\|SFTP protocol]] too.		WinSCP uses ''scp'' command to perform the transfer.
