第 156 行:意外标记“fi”附近的语法错误

如何将这两个语句放在一起？

Answer 1

在每个测试的最后一个 ] 之前必须有一个空格。

例如:

if [ $DISTRO = "REDHAT"] || [ $DISTRO = "FEDORA"]; then

必须重写为:

 if [ "$DISTRO" = REDHAT ] || [ "$DISTRO" = FEDORA ]; then

或

if test "$DISTRO" = REDHAT || test "$DISTRO" = FEDORA; then

另请注意，没有理由引用文字字符串，但您应该引用变量。

你也可以这样做:

if test "$DISTRO" = REDHAT -o "$DISTRO" = FEDORA; then

或

case "$DISTRO" in
REDHAT|FEDORA) ... ;;
DEBIAN) ... ;;
