O problema é provavelmente as marcas de aspas Unicode: altere-as para aspas ASCII regulares:
$ echo “ (component-library-search \“${HOME}/gaf/symbols/\”) ”
bash: syntax error near unexpected token '('
enquanto
$ echo " (component-library-search \"${HOME}/gaf/symbols/\") "
(component-library-search "/home/steeldriver/gaf/symbols/")
