bash shell 函数体中的错误重定向
Error redirection in the body of the bash shell function
我有一个如下所示的脚本：
#!/bin/bash
#func.sh
func(){
badcommand1
echo "OK"
badcomand2
}
func 2>&1 > err.log
#The top line is in the file
我的目标是将所有输出和错误重定向到文件 err.log 但不幸的是，它只打印
“确定”到日志文件。
Bash 版本是：
GNU bash，版本 4.2.46(2)-release (x86_64-redhat-linux-gnu)
有人可以帮忙吗？
我建议交换 2>&1 和 > err.log。
来自man bash：
Note that the order of redirections is significant. For example,
the command
ls > dirlist 2>&1
directs both standard output and standard error to the file
dirlist, while the command
ls 2>&1 > dirlist
directs only the standard output to file dirlist, because the
standard error was duplicated from the standard output before
the standard output was redirected to dirlist.
