Search directory for file (without searching within files)

ls | Select-Object Name -ExpandProperty Name | Select-String SEARCHFILENAME

If Select-Object was removed, it would search within text files

ls *.apk | ForEach-Object {echo $_.Name}

Extra: Install all apks in folder via adb

$count=0; ls *.apk | ForEach-Object {echo "Installing: $_"; adb install $_.Name; $count++}; echo "Attempted to install $count apps."

Show hidden files when using Get-Childitem (ls, dir or gci)

ls -Force

Print Path Environment Variables as Plain String

ls env:Path | Select-Object -ExpandProperty Value 

Print Path Environment Variables and make it more readable

ls env:Path | Select-Object -ExpandProperty Value | % {$_.replace(";","`n")}

This:

% {$_.replace(";","`n")}

is very similar to using bash's sed
Also note that newlines, return carriage etc. are done by backticks (`) (This is the same button as ~) i.e:

# `n for new line
# `r for return carriage
