Run bash commands from txt file

Question

I have some commands in txt file and I need to execute all them line by line. How could I do it?

Accepted Answer

Just do `bash file`:

```
$ cat file 
date
echo '12*12' | bc

$ bash file
Mon Nov 26 15:34:00 GMT 2012
144
```

In case of aliases just run `bash -i file`

No need to worry about file extensions or execution rights.
