Second, there's a reason the current directory is not included for running executables. It's not "missing", it's on purpose. It's to prevent people from dumping malign files into a folder you frequent and having you accidentally run them.

Ok, I kinda get that it might be about having executables in permissions protected directories, but if all you need to do is use the absolute pathname, it doesn't seem like much security. Especially if it's just a dot-slash. Of course, it forces you to make sure executing it is what you want to do.
So you guys think that's what the deal is?

I have no need to put these practice scripts I'm doing in my PATH. It's not an issue - just something I was wondering about. If I ever write something useful, I'll stick it in /usr/local/bin Smilie

I should have mentioned - I'm running Mac OS, bash shell.

gsettings

GSETTINGS(1)							   User Commands						      GSETTINGS(1)

NAME

       gsettings - GSettings configuration tool

SYNOPSIS

       gsettings get SCHEMA [:PATH]  KEY

       gsettings monitor SCHEMA [:PATH]  [KEY]

       gsettings writable SCHEMA [:PATH]  KEY

       gsettings range SCHEMA [:PATH]  KEY

       gsettings set SCHEMA [:PATH]  KEY VALUE

       gsettings reset SCHEMA [:PATH]  KEY

       gsettings reset-recursively SCHEMA [:PATH]

       gsettings list-schemas

       gsettings list-relocatable-schemas

       gsettings list-keys SCHEMA [:PATH]

       gsettings list-children SCHEMA [:PATH]

       gsettings list-recursively [SCHEMA [:PATH]]

       gsettings help [COMMAND]

DESCRIPTION

       gsettings offers a simple commandline interface to GSettings. It lets you get, set or monitor an individual key for changes.

       The SCHEMA and KEY arguments are required for most commands to specify the schema id and the name of the key to operate on. The schema id
       may optionally have a :PATH suffix. Specifying the path is only needed if the schema does not have a fixed path.

       When setting a key, you also need specify a VALUE The format for the value is that of a serialized GVariant, so e.g. a string must include
       explicit quotes: "'foo'". This format is also used when printing out values.

COMMANDS

       get
	   Gets the value of KEY. The value is printed out as a serialised GVariant.

       monitor
	   Monitors KEY for changes and prints the changed values. If no KEY is specified, all keys in the schema are monitored. Monitoring will
	   continue until the process is terminated.

       writable
	   Finds out whether KEY is writable.

       range
	   Queries the range of valid values for KEY.

       set
	   Sets the value of KEY to VALUE. The value is specified as a serialised GVariant.

       reset
	   Resets KEY to its default value.

       reset-recursively
	   Reset all keys under the given SCHEMA.

       list-schemas
	   Lists the installed, non-relocatable schemas. See list-relocatable-schemas if you are interested in relocatable schemas.

       list-relocatable-schemas
	   Lists the installed, relocatable schemas. See list-schemas if you are interested in non-relocatable schemas.

       list-keys
	   Lists the keys in SCHEMA.

       list-children
	   Lists the children of SCHEMA.

       list-recursively
	   Lists keys and values, recursively. If no SCHEMA is given, list keys in all schemas.

       help
	   Prints help and exits.
