markdown 将所有控制台输出重定向到文件

Posted 2021-05-06

The output of a program could be send to stderr or stdout. In the case you want to manage both separatelly:
```
foo > stdout.txt 2> stderr.txt
```

or if you want in same file for both message streams:

```
foo > allout.txt 2>&1
```

You can also maintain the regular output using 'tee' to split the data flow:

```
foo 2>&1 | tee allout.txt
```

Note: this works in (ba)sh, check your shell for proper syntax
