KSH redirect stdout and stderr to a file on Linux or Unix

To redirect the standard output (stdout) and standard error (stderr) of a command to a file in KSH (Korn Shell), you can use the > and 2> operators.

Here is an example of how to redirect stdout and stderr to a file:

# Redirect stdout and stderr to a file
command > output.txt 2>&1

This will redirect the stdout and stderr of the command to the file "output.txt".

You can also use the >> operator to append the output to an existing file:

# Append stdout and stderr to a file
command >> output.txt 2>&1

It is important to note that the > and >> operators overwrite and append the file, respectively, and will create the file if it does not exist. If you want to create the file if it does not exist, but leave it unchanged if it does exist, you can use the >| operator.

For more information on redirecting output in KSH, you can consult the KSH manual or online documentation.
