Administrar scripts en un programa de código abierto

Algo extraño sucedió cuando intenté usar un código abierto después de la compilación de GNU, aquí está:

  1. No se presenta ningún error en ./configure ./make ./make install

  2. Cuando intento usarlo, hay algunas variables en estos scripts de administración sin valor de inicialización. Este script se llama "ionadmin" y una de estas variables NULL es, por ejemplo, "NO_GLOB_SUBST".

  3. No puedo encontrar este nombre "NO_GLOB_SUBST" en el documento. De lo contrario, no puedo encontrar la operación de asignación en la ruta raíz usando esto:

    buscar ~/ -type f |xargs grep 'NO_GLOB_SUBST'

Y ahí está el guión:

#!/bin/bash
# ionadmin - temporary wrapper script for .libs/ionadmin
# Generated by libtool (GNU libtool) 2.4.2 Debian-2.4.2-1.7ubuntu1
#
# The ionadmin program cannot be directly executed until all the libtool
# libraries that it depends on are installed.
#
# This wrapper script should never be moved out of the build directory.
# If it is, it will not operate correctly.

# Sed substitution that helps us do robust quoting.  It backslashifies
# metacharacters that are still active within double-quoted strings.

Ésta es mi pregunta : ¿En qué condiciones el autor de este script utiliza estas variables no inicializadas? ¿O hay algún error que ignoré? Hay otra pregunta que he publicado:HACER CLIC

tu hiciste la preguntaaquí, y se observó que NO_GLOB_SUBSTes una palabra clave zsh (veríndice de opciones). EsoEnlacesa

GLOB_SUBST <C> <K> <S>

Trate los caracteres resultantes de la expansión de parámetros como elegibles para la expansión y generación de nombres de archivos, y los caracteres resultantes de la sustitución de comandos como elegibles para la generación de nombres de archivos. Las llaves (y las comas intermedias) no son elegibles para la expansión.

Entonces... " NO_" al frente convierte esa característicaapagado.

Sin un signo de dólar ( $) delante del nombre, ni zsh ni bash lo tratarían como unvariableen lugar de como unnombreopalabra clave.
