How (or in which file) does JShell store its configuration settings?

Question

The doc says:

Remember that the startup scripts are loaded into the current session only when the state is reset. The contents of the script is stored, not a reference to the script.

(https://docs.oracle.com/javase/9/jshell/scripts.htm#JSHEL-GUID-AC2A6582-6A9A-48B1-ABBF-4C9536CDFD07)

For example,

/set start -retain mystartscript.jsh

But where does it store the contents of mystartscript.jsh?

Answer 1

像在示例中一样使用相对文件名：

/set start -retain mystartscript.jsh

JShell会在[ mystartscript.jsh ] / user.home

中寻找mystartscript.jsh

您也可以给它一个绝对的文件路径：

/set start -retain /my_custom_jshell_scripts/mystartscript.jsh
