vim創建新文件的命令，centos java創建文件_CentOS java生成文件并賦予權限的問題

2、檢查文件是否允許：

file.canExecute(); – return true, file is executable; false is not.

file.canWrite(); – return true, file is writable; false is not.

file.canRead(); – return true, file is readable; false is not.

3、設置文件權限：

vim創建新文件的命令、file.setExecutable(boolean); – true, allow execute operations; false to disallow it.

file.setReadable(boolean); – true, allow read operations; false to disallow it.

file.setWritable(boolean); – true, allow write operations; false to disallow it.

Runtime.getRuntime().exec("chmod 777 filename");
