Linux 文件“/proc/{processId}/cmdline”的长度限制有多长？

我有一个java进程，它的类路径包含许多JAR，因此启动命令非常长

假设进程id为110101，当我逐个命令检查该命令时，我发现该命令不完整，仅包含约4000个字符

是否有其他方法显示原始启动命令

 man proc

 /proc/[pid]/cmdline
              This holds the complete command line for the process, unless
              the process is a zombie.  In the latter case, there is nothing
              in this file: that is, a read on this file will return 0
              characters.  The command-line arguments appear in this file as
              a set of strings separated by null bytes ('\0'), with a
              further null byte after the last string.

它可能不会通过cat文件为您提供所有参数
