create two text files in your home directory. The first file should be named ls.txt and contain the complete manual page for the ls command. The second file should be named cal.txt and contain the calendar for June 2019.
To create the ls.txt file with the complete manual page for the ls command, you can use the following command:
```
man ls > ~/ls.txt
```
This will redirect the output of the `man` command for `ls` to a file named `ls.txt` in your home directory (`~`).
To create the cal.txt file with the calendar for June 2019, you can use the following command:
```
cal 06 2019 > ~/cal.txt
```
This will generate the calendar for June 2019 using the `cal` command and redirect the output to a file named `cal.txt` in your home directory (`~`).
