linux - 如何在 bash shell 脚本中包含文件

Question

有没有办法在 shell 脚本中包含另一个 shell 脚本以便能够访问其功能？

就像在 PHP 中一样，您可以将 include 指令与其他 PHP 文件一起使用，以便通过调用函数名来运行其中包含的函数。

Answer 1

只需放入您的脚本中:

source FILE

或者

. FILE # POSIX compliant

$ LANG=C help source
source: source filename [arguments]
Execute commands from a file in the current shell.

Read and execute commands from FILENAME in the current shell.  The
entries in $PATH are used to find the directory containing FILENAME.
If any ARGUMENTS are supplied, they become the positional parameters
when FILENAME is executed.

Exit Status:
Returns the status of the last command executed in FILENAME; fails if
FILENAME cannot be read.
