在 Java 中从字符串创建文件时添加了奇怪的字符
当尝试在 Java 中创建 bash 脚本（.sh 文件）时，随机字符会添加到文件的开头。
因此，使用 sbatch 命令提交脚本时，该脚本会被 SLURM 拒绝。
我的代码：
String ss = "#!/bin/bash\n"; // script String
ss+= "#SBATCH --job-name="+scriptJobName+"\n" // scriptJobName is a String that's initialized earlier
try{
FileOutputStream fos = new FileOutputStream(scriptName); // Where scriptName is a String that is initialized earlier.
DataOutputStream outStream = new DataOutputStream(new BufferedOutputStream(fos));
outStream.writeUTF(ss);
outStream.close();
}catch(IOException e){
System.err.println("ERROR: writing sub-job execution script "+e);
}
脚本创建：
#!/bin/bash
#SBATCH --job-name=ColComp
[编者注：生成的脚本的第一行前面有两个不可见的字符，0x05和0x01，似乎只有在编辑时才可见模式，即使格式化为代码。这似乎是“永远不要发布代码图片”的反例:-) 
]
SLURM 提交错误：
sbatch：错误：这看起来不像批处理脚本。第一个 sbatch：错误：行必须以 # 开头！接下来是通往 口译员。 sbatch：错误：例如：#!/bin/sh
询问
如何防止添加这些不需要的字符？ （或自动删除它们 - 在 Java 中）
When trying to create a bash script (.sh file) in Java, random characters are added to the beginning of the file.
As a result, the script is rejected by SLURM when submitted using the sbatch command.
My Code:
String ss = "#!/bin/bash\n"; // script String
ss+= "#SBATCH --job-name="+scriptJobName+"\n" // scriptJobName is a String that's initialized earlier
try{
FileOutputStream fos = new FileOutputStream(scriptName); // Where scriptName is a String that is initialized earlier.
DataOutputStream outStream = new DataOutputStream(new BufferedOutputStream(fos));
outStream.writeUTF(ss);
outStream.close();
}catch(IOException e){
System.err.println("ERROR: writing sub-job execution script "+e);
}
Script Created:
#!/bin/bash
#SBATCH --job-name=ColComp
[Editor's Note: The first line of the generated script is preceded by two invisible characters, 0x05 and 0x01, which seem to be visible only in edit mode, even when formatted as code. This seems to be the counterexample to "never post pictures of code" :-)

SLURM Submission Error:
sbatch: error: This does not look like a batch script. The first
sbatch: error: line must start with #! followed by the path to an
interpreter. sbatch: error: For instance: #!/bin/sh
Asks
How can I prevent these unwanted characters from being added? (or automatically remove them - in Java)

问题是您使用了 DataOutputStream。这里不需要，只需写入
FileOutputStream即可。 0x05 0x01 是一个对象标头，仅当稍后由 DataInputStream 读取输出时才有意义。The problem is you used a
DataOutputStream. That is unnecessary here, just write to theFileOutputStream. The 0x05 0x01 is an object header that is meaningful only when the output is read later by aDataInputStream.
