Lua错误：无法创建进程：proc_open(/dev/null): failed to open stream: Operation not permitted Lua错误：无法创建进程：proc_open(/dev/null): failed to open stream: Operation not permitted Lua错误：无法创建进程：proc_open(/dev/null): failed to open stream: Operation not permitted

Usage

Lua错误：无法创建进程：proc_open(/dev/null): failed to open stream: Operation not permitted

Returns the position of first appearance of sub_string in text.

  • The comparison is case sensitive.
  • Returns -1 if sub_string not found
  • Character position is 1 based (not 0 based as usual in calculations).
  • If sub_string is empty, this routine returns 1. This case will often have to be handled specially.

Examples

In the examples, the string to be searched is <syntaxhighlight lang="text" class="" id="" style="" inline="1">Abcdefghijklm</syntaxhighlight>:

  • A; Lua错误：无法创建进程：proc_open(/dev/null): failed to open stream: Operation not permitted
  • a; Lua错误：无法创建进程：proc_open(/dev/null): failed to open stream: Operation not permitted
