This determines the name of the user\*(Aqs initial login command\&. A normal user may only change the login shell for her own account; the superuser may change the login shell for any account\&. +.SH "OPTIONS" +.PP +The options which apply to the +\fBchsh\fR +command are: +.PP +\fB\-h\fR, \fB\-\-help\fR +.RS 4 +Display help message and exit\&. +.RE +.PP +\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR +.RS 4 +Apply changes in the +\fICHROOT_DIR\fR +directory and use the configuration files from the +\fICHROOT_DIR\fR +directory\&. Only absolute paths are supported\&. +.RE +.PP +\fB\-s\fR, \fB\-\-shell\fR\ \&\fISHELL\fR +.RS 4 +The name of the user\*(Aqs new login shell\&. Setting this field to blank causes the system to select the default login shell\&. +.RE +.PP +If the +\fB\-s\fR +option is not selected, +\fBchsh\fR +operates in an interactive fashion, prompting the user with the current login shell\&. Enter the new value to change the shell, or leave the line blank to use the current one\&. The current shell is displayed between a pair of +\fI[ ]\fR +marks\&. +.SH "NOTE" +.PP +The only restriction placed on the login shell is that the command name must be listed in +/etc/shells, unless the invoker is the superuser, and then any value may be added\&. An account with a restricted login shell may not change her login shell\&. For this reason, placing +/bin/rsh +in +/etc/shells +is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell back to its original value\&. +.SH "CONFIGURATION" +.PP +The following configuration variables in +/etc/login\&.defs +change the behavior of this tool: +.PP +\fBCHSH_AUTH\fR (boolean) +.RS 4 +If +\fIyes\fR, the +\fBchsh\fR +program will require authentication before making any changes, unless run by the superuser\&. +.RE +.PP +\fBLOGIN_STRING\fR (string) +.RS 4 +The string used for prompting a password\&. The default is to use "Password: ", or a translation of that string\&. If you set this variable, the prompt will not be translated\&. +.sp +If the string contains +\fI%s\fR, this will be replaced by the user\*(Aqs name\&. +.RE +.SH "FILES" +.PP +/etc/passwd +.RS 4 +User account information\&. +.RE +.PP +/etc/shells +.RS 4 +List of valid login shells\&. +.RE +.PP +/etc/login\&.defs +.RS 4 +Shadow password suite configuration\&. +.RE +.SH "SEE ALSO" +.PP +\fBchfn\fR(1), +\fBlogin.defs\fR(5), +\fBpasswd\fR(5)\&. -- cgit v1.2.3
