Get autocompletion when invoking a "read" inside a Bash script
提问by Ingo Fischer
Inside my Bash script, I'm reading some variables entered by the user with read:
在我的 Bash 脚本中,我正在读取用户输入的一些变量read:
read -p "Glassfish Path:" GF_DIR
Now I want that the user gets a autocompletion when he has to enter a directory, like when you are on the Bash shell. So when he enters the first letters of a directory, he can autocomplete it by hitting TAB. Is that possible?
现在我希望用户在必须进入目录时获得自动完成功能,就像您在 Bash shell 上一样。因此,当他输入目录的第一个字母时,他可以通过按 TAB 来自动完成它。那可能吗?

Try:
尝试:
read -e -p "Glassfish Path:" GF_DIR
-e启用阅读线:
-e
If the standard input is coming from a terminal, Readline is used
to obtain the line.
