How to filter directory listing by using a property from the resultant list itself in Java?

it fixes the issue I have a directory called /home/ftp which contains sub-directories like this: , I think what you're expecting as an output is:
code :
List<String> dirToProcess = list.stream()
                .filter(name -> name.contains(".ok") && list.contains(name.substring(0, name.indexOf(".ok"))))
                .map(name -> name.substring(0, name.indexOf(".ok")))

I wish this help you I'm not sure if you were taking about unix shell scripting, but here's a working example for bash:
code :

Exclude=("a" "b" "c")
Listing=(`ls -1Q`)

Files=( $(comm -23 <( printf "%s\n" "${Listing[@]}" ) <( printf "%s\n" "${Exclude[@]}"
) ) )

echo ${Files[@]}

How to filter a directory listing with a regular expression in Clojure

I hope this helps you . Given a regex and a directory path, how do I get a seq of files whose path matches the regex?
code :
(defn regex-file-seq
  "Lazily filter a directory based on a regex."
  [re dir]
  (filter #(re-find re (.getPath %)) (file-seq dir)))

recursive directory iterator results: filter out specific characters from resultant paths

To fix this issue Just add another checker inside, and try to use ->getPathname() instead:
code :
if($object->isDir() && strpos($object->getPathname(), '.') === false) {
    // do some stuff

Filter Directory Listing By Date Listed In Name

may help you . Here is an example using regex and some dummy files names. In your example you would want to replace $fileNames with your initial Get-ChildItem command. I am just piping the file names to where clause that uses a regex to capture the year, month, and day. I then pipe that to another where clause that uses the captured numbers to construct a System.DateTime object and compares that to the start and end times.
code :
$startDate = New-Object -TypeName System.DateTime -ArgumentList @(2016, 1, 2)
$endDate = New-Object -TypeName System.DateTime -ArgumentList @(2016, 1, 4)

$fileNames = @(

$fileNames | 
? { $_ -match "_(\d+)-(\d+)-(\d+)_" } |
? { 
    $date = New-Object System.DateTime -ArgumentList $Matches[1], $Matches[2], $Matches[3] 
    $date -ge $startDate -and $date -le $endDate
Get-Childitem -Path $Directory -OutBuffer 1000 -filter "*.log" | 
? { $_.Name -match "_(\d+)-(\d+)-(\d+)_" } |
? { 
    $date = New-Object System.DateTime -ArgumentList $Matches[1], $Matches[2], $Matches[3] 
    $date -ge $startDate -and $date -le $endDate
} |
Select FullName, Name

will be helpful for those in need I have written the following code: , You could write it, like so:
code :
a_list = [{y: x * y for y in range(5) if (x and y) and (x * x != x * y)}
          for x in range(5)]    

# [{}, {2: 2, 3: 3, 4: 4}, {1: 2, 3: 6, 4: 8}, {1: 3, 2: 6, 4: 12}, {1: 4, 2: 8, 3: 12}]
