[英]Java Jar file SoftLink in Linux
I have created a jar file , it reads from standard input and print them out to the standard output. 我创建了一个jar文件,它从标准输入读取并将它们打印到标准输出。
Below is how you can use the app: 以下是如何使用该应用程序:
cat /ephemeral/test/input | java -jar /ephemeral/test/Hello.jar >> /ephemeral/test/output
I am wondering is it possible to add my Hello.jar to be a Linux Command, let's say -hello-: 我想知道是否有可能将我的Hello.jar添加为Linux命令,让我们说-hello-:
So next time I could just do something like: 所以下次我可以做一些像:
hello /ephemeral/test/input /ephemeral/test/output
I am not that much familiar with Linux Soft Link and Java, so any help or information would be appricated! 我对Linux Soft Link和Java不太熟悉,所以任何帮助或信息都会被批评!
UPDATE: thanks for reno's inspiring answer, I put the cat ... | 更新:感谢里诺的鼓舞人心的回答,我把猫... | .. >> .. into a shell script hello.sh.
.. >> ..进入shell脚本hello.sh。 Now I can do something like:
现在我可以这样做:
./hello.sh /inputpath/input outputpath/output
(Note: you should not use $0, $0 is actually the name the file itself instead of input arguments) (注意:你不应该使用$ 0,$ 0实际上是文件本身的名称而不是输入参数)
Now, the last question is how could you access the shell script EVERYWHERE, like how you call basic shell cmds: ls..cat..echo.. 现在,最后一个问题是如何在任何地方访问shell脚本,就像你调用基本的shell cmd:ls..cat..echo ..
I have read a tutorial described exactly what I want(reach to the end of the tutorial directly): 我读了教程正是我想要的描述(达到本教程的最后直接):
I created a bin folder which is like mkdir /home/ubuntu/bin and put my shell script there. 我创建了一个bin文件夹,就像mkdir / home / ubuntu / bin一样,并将我的shell脚本放在那里。 However, I still have problem do what the author described:
但是,我仍然有问题做作者所描述的:
hello input output (in my case) 你好输入输出(在我的情况下)
Does anyone know what is going wrong here? 有谁知道这里出了什么问题?
执行此操作的方法是编写包含必要的java -jar
命令的shell脚本(通常为hello.sh
)。
you can write a shell script say test.sh and copy your code to test.sh 你可以写一个shell脚本说test.sh并将你的代码复制到test.sh
cat $0 | 猫$ 0 | java -jar /ephemeral/test/Hello.jar >> $1
java -jar /ephemeral/test/Hello.jar >> $ 1
and execute the script by passing your input and output file name something like this: 并通过传递输入和输出文件名来执行脚本,如下所示:
test.sh /ephemeral/test/input /ephemeral/test/output test.sh / ephemeral / test / input / ephemeral / test / output
