我把一个软件base加密后放到shell里，shell现在大小有317KB多了
我还想加密这个shell，但是
[@root]# ./shc -r -f a.sh
shc: WARNING!!
Scripts of length near to (or higher than) the current System limit on
"maximum size of arguments to EXEC", could comprise its binary execution.
In the current System the call sysconf(_SC_ARG_MAX) returns 131072 bytes
and your script "a.sh" is 323569 bytes length.
好像超出系统arg max的限制了，还有什么好的方法对大于131072byte的shell脚本加密吗？

unlimit -a 一下就知道了...

ulimit好像不管这个吧？arg_max是系统的硬限制
The kernel's exec() function has NCARGS as the hard-coded limit on the number of bytes of argument buffer to use, and NCARGS is #defined to be ARG_MAX, so you won't be able to change this without (at least) recompiling the kernel. I suspect that changing this value may also affect the libraries and startup code for user-mode applications, but I haven't checked that code to be sure.
