To redirect the output of the `ls` and `ps` commands into files, we can use the `>` operator followed by the file name to which we want to write the output. Here are the commands:
1. Redirecting the output of `ls` command to a file named `list.txt`:
```
ls > list.txt
```
This command will write the output of `ls` command (i.e., the list of files and directories in the current directory) to a file named `list.txt`.
2. Redirecting the output of `ps` command to a file named `processes.txt`:
```
ps > processes.txt
```
This command will write the output of `ps` command (i.e., the list of running processes) to a file named `processes.txt`.
Note that if the file already exists, the output will overwrite the existing contents of the file. If you want to append the output to the existing content of the file, you can use the `>>` operator instead of `>`.
