The Bash/KSH and POSIX shell provides a file redirection option to redirect the output of commands to a file using the following two operators:

1. > is output redirection symbol.
2. >> is append output redirection symbol.

So Your command would be

$PS -e > /root/output.txt

Please note that output.txt file will be created if it doesn't exist. And if file output.txt exist it will be overwritten.

I would read up on using the pipe character '>' for redirecting stdout/console output - for example

$PS -e >Process-data.txt

or

$PS -e >> Process-data.txt

a single '>' creates a file and stores the output to it (from the stdout of the ps command)
a double '>' ie '>>' appends stdout data to the 'redirection target'

does that help ?

That's a redirection character, a pipe is '|'.
