Shell script for running Java programs under Linux

Vim creates a new shell file, such as my file named Java_run, which reads:

echo "Please enter the Java file path you want to compile:"

Read Path

#分离路径和文件名
var1= ' dirname $path ' #路径
Var2= ' basename $path ' #文件名
CD $var 1
Javac $var 2
Java ${var2%.*} #去掉文件名的后缀

RM ${var2%.*}.class

OK, save quit vim.

chmod 777 Java_run #加可执行的权限

run the script,./java_run.

extension: If you want to make it your own command (just like LS), here are the following methods:

Home directory (that is, login user directory) Create a new directory, named Bin bar, copy java_run files to the directory, edit the. profile file, add at the end:

Path= $PATH: $HOME/bin
Save exit. After you type the command java_run can see the same effect as./java_run.
