如何确定Bash脚本被中断的位置？

我的代码

  echo "Script error"
  echo "File name: ?"
  echo "Line num : ?"
}

r1 . /tmp/1 || exit 1
r2 . /tmp/2 || exit 1
..

r3541 . /tmp/3541 || exit 1
r3542 . /tmp/3542 || exit 1

试试这个：

#!/bin/bash

trap stop exit

stop()
{
  echo "Script error"
  echo "File name: $0"
  echo "Line num : $l"
}

r1 . /tmp/1 || { l=$LINENO; exit 1; }
r2 . /tmp/2 || { l=$LINENO; exit 1; }
..
..
r3541 . /tmp/3541 || { l=$LINENO; exit 1; }
r3542 . /tmp/3542 || { l=$LINENO; exit 1; }
