If you are using an xterm emulation capable terminal emulator, such as PuTTY or xterm on Linux desktop, this command will replace the title of that terminal window.

Even though the string between the quotes is typed as literals, it needs a little more finesse to make it work. Here is how it is done key-by-key:
echo "( ctrl-v then ctrl-[ )0;Enter_Title_String_Here( ctrl-v then ctrl-g )"( enter )
ctrl-v : means hold down ctrl key and hit v at the same time like you are pasting in windoze ; also please don't type the parentheses, i.e., ( and )

Here's an annotated version of the command, using full-names instead of aliases. It is exactly equivalent to the short-hand version.
# Recursively list all the files in the current directory.
Get-ChildItem -Recurse |
# Filter out the sub-directories themselves.
Where-Object { return -not $_.PsIsContainer; } |
# Group the resulting files by their extensions.
Group-Object Extension |
# Pluck the Name and Count properties of each group and define
# a custom expression that calculates the average of the sizes
# of the files in that group.
# The back-tick is a line-continuation character.
Select-Object `
Name,
Count,
@{
Name = 'Average';
Expression = {
# Average the Length (sizes) of the files in the current group.
return ($_.Group | Measure-Object -Average Length).Average;
}
} |
# Format the results in a tabular view, automatically adjusted to
# widths of the values in the columns.
Format-Table -AutoSize `
@{
# Rename the Name property to something more sensible.
Name = 'Extension';
Expression = { return $_.Name; }
},
Count,
@{
# Format the Average property to display KB instead of bytes
# and use a formatting string to show it rounded to two decimals.
Name = 'Average Size (KB)';
# The "1KB" is a built-in constant which is equal to 1024.
Expression = { return $_.Average / 1KB };
FormatString = '{0:N2}'
}
