bash中的运算符|&是什么意思？
What is the meaning of operator |& in bash?
in Linux bash 我看到脚本使用 |& 运算符，例如：
/opt/program.sh |& tee -a /var/log/program.log
|& 运算符的含义是什么？
此致
根据 §3.2.3 "Pipelines" in the Bash Reference Manual，|& 类似于 |，除了：
If ‘|&’ is used, command1’s standard error, in addition to its standard output, is connected to command2’s standard input through the pipe; it is shorthand for 2>&1 |. This implicit redirection of the standard error to the standard output is performed after any redirections specified by the command.
也就是说 — /opt/program.sh 打印到标准输出 或 到标准错误的任何内容都将通过管道传输到 tee -a /var/log/program.log.
