Hi I define a global alias: alias -g EMPTYSTR='[[:space:][:INCOMPLETE:][:INVALID:]$'\e']#' to then use it in [[ "" == EMPTYSTR ]]. It works, however any addition to the alias name makes it inactive, e.g.: [[ "" == (EMPTYSTR) ]] [[ "" == (#b)(EMPTYSTR) ]] won't work. Is there any way to somehow improve the alias recognizability? -- Best regards, Sebastian Gniazdowski
