重击-参数不起作用

Question

Hello I am running a javac command (lstf is a file)

javac @$lstf

For some reason, I get an error saying javac: file not found: path/to/dir/*.java . Whenever I type the args in manually in Terminal javac works.

Here is the code:

mkdir "$out"

cd src
scan

"$cc" $cflags -d "../$out" @${lstf}
rm -rf $lstf
cd ../

scan is the function that generates all the paths in the file $lstf - it works fine

Answer 1

You need to say javac @foo , and lstf = foo ?

Whenever you are in a situation where variable names are hard to decipher, you can use ${var} syntax instead of just $var :

javac @${lstf}

Answer 2

如果文件路径存储在lstf变量中，则将其命名为

javac "$lstf"
