linux - __LINE__ 相当于 Linux shell

Question

我正在编写一个相当大的 shell 脚本。有没有办法从该脚本打印脚本的行号？基本上我想要类似于 gcc LINE 宏的东西。这将帮助我调试我的脚本。

提前致谢

BASH_LINENO
  An array variable whose members are the line numbers in source files corresponding to each member of FUNCNAME. ${BASH_LINENO[$i]} is the line number in the source file where ${FUNCNAME[$i]} was called. The corresponding source file name is ${BASH_SOURCE[$i]}. Use LINENO to obtain the current line number.
