以编程方式创建的文件在Linux中变为NULL [英] Programatically created files become NULL in Linux

问题描述

我有一个Shell脚本，可以通过将变量的内容写入内存位置中的文件来以编程方式创建文件.

I've a shell script which create files programmatically by writing the contents of a variable to a file in the memory location.

file=/downloads/fileName.crt
variable="These contents are to be
          written to the file"
echo "$variable" > "$file"

这很好.我可以看到文件已写入，而不是NULL.但是有时在运行此脚本后并重新引导后，文件内容变为NULL.为什么会这样?

This works fine. I'm able to see that the file is written to and not NULL. But sometimes after running this script and after a reboot, the file contents become NULL. Why is this happening?
