How do I use Format-Table without truncation of values?

The $FormatEnumerationLimit preference variable doesn’t apply here, because its purpose is to determine how many elements of a collection-valued property to display (e.g, $FormatEnumerationLimit = 2; [pscustomobject] @{ prop = 1, 2, 3 } prints (at most) 2 elements from .prop‘s value and hints at the existence of more with ...; e.g., {1, 2...}).

Instead, you must:

• (a) ensure that individual columns don’t truncate their values on display:

  • Pipe to Format-Table -Autosize first.

• and (b) ensure that the overall output width can fit all columns:

  • Pipe to Out-File -Width with a sufficiently large value (don’t use [int]::MaxValue, though, because every line of tabular output gets padded to that very width^[1])
    .

    • Caveat: If you don’t set -Width explicitly – as would happen if you just used >, for instance – the current console window‘s width is used – whatever it happens to be.

For instance:

# Assumes that the objects in $results only contain the properties
# of interest (MachineName, ServiceName, Status, StartType); you 
# can also pass an explicit list of output properties to Format-Table, however.
$results | Format-Table -AutoSize | Out-File -Width 512 C:\log.txt -Append

Note: To preview the output in the console – which may involve line-wrapping – use
Out-String -Width 512 instead.
