pmshell

Description

Type integer READONLY

pmshell initializes to true if a Privilege Manager for Unix shell program (such as pmksh, pmsh, pmcsh, pmloginshell, and pmbash) is running; otherwise, the variable is undefined.

Example
if (defined pmshell) 
{ 
   printf ("Now running: %s\n", pmshell_prog); 
   pmshell_restricted = 1; 
   pmshell_checkbuiltins = 1; 
   pmshell_reject = "You are not allowed to run this command"; 
   pmshell_allow = {"ls","grep","cat"}; 
   pmshell_forbid = append(pmshell_forbid, "passwd"); 
   pmshell_forbid = append(pmshell_forbid, "kill"); 
} 
else 
{ 
   printf("Not running a command within %s\n", pmshell_prog); 
   accept; 
}

pmshell_builtin

Description

Type integer READONLY

pmshell_builtin is a constant value that identifies a shell builtin command. Use it to compare with the value of the pmshell_cmdtype variable.

Example
if (defined pmshell_cmd){ 
   if ((user in safe_shell_list) && (pmshell_cmdtype == pmshell_builtin)) 
   { 
      #allow all built-ins for selected users accept; 
   } 
}

pmshell_cmd

Description

Type integer READONLY

pmshell_cmd is only defined if the command is a Privilege Manager for Unix shell program (in which case it is set to false) or the command is a shell subcommand running from a Privilege Manager for Unix shell program (in which case it is set to true).

This variable is only applicable to the pmsh, pmksh, pmcsh, and pmbash programs.

Example
if (defined pmshell_cmd){ 
   if (user !in safe_shell_list) 
   { 
      #check builtins 
      pmshell_checkbuiltins=true; 
   } 
}

pmshell_cmdtype

Description

Type integer READONLY

pmshell_cmdtype is only defined if the command is a shell subcommand running from a Privilege Manager for Unix shell.

This variable is only applicable to the pmsh, pmcsh, pmksh, and pmbash programs.

It is set to one of these constant values: pmshell_builtin, pmshell_script, or pmshell_exe.

Example
if (defined pmshell_cmd){ 
   if (user !in safe_shell_list) 
   { 
      #check builtins 
      pmshell_checkbuiltins=true; 
   } 
}
