我正在查看一些正在为我当前项目工作的老人编写的 shell 脚本。在文件末尾，它简单地包含文件夹/文件路径，例如，
/home/udhay-dev/work/udhay/bin/rm-vhosts
/home/udhay-dev/work/udhay/bin/vhosts
/home/udhay-dev/work/udhay/bin/apache
在文件末尾。当执行这些行时，它会抛出
vhost.sh: line 22: /home/udhay-dev/work/udhay/bin/rm-vhosts: Is a directory
vhost.sh: line 23: /home/udhay-dev/work/udhay/bin/vhosts: Permission denied
vhost.sh: line 24: /home/udhay-dev/work/udhay/bin/apache: Is a directory
但我对这些一无所知，因为我对 Ubuntu 和 Shell 脚本都几乎不熟悉。在 shell 脚本中简单地包含这些行的原因或目的是什么？请帮忙。
答案1
vhost.sh: line 22: /home/udhay-dev/work/udhay/bin/rm-vhosts: Is a directory
rm-vhosts显示目录内有名为的目录/home/udhay-dev/work/udhay/bin。
vhost.sh: line 23: /home/udhay-dev/work/udhay/bin/vhosts: Permission denied
vhosts显示目录内有名为的文件/home/udhay-dev/work/udhay/bin。
vhost.sh: line 24: /home/udhay-dev/work/udhay/bin/apache: Is a directory
apache显示目录内有名为的目录/home/udhay-dev/work/udhay/bin。
vhost.sh是脚本名称。line xx表示脚本中抛出上述消息的行号。
