cd $(Split-Path $PROFILE)

Example of finding a file somewhere in the filesystem and outputting the full path and filename.

Get-ChildItem -Recurse -Filter "csc.exe" | foreach {$_.Fullname}

Use a regex with -Match operator for more advanced filtering.

gci -Recurse | where {$_.Name -Match "^csc.*"} | foreach {$_.Fullname}

$exclude = @("*.log", "*.tmp", "log*.txt")
$files = ls -Recurse -Exclude $exclude
Compress-Archive -Path $files -DestinationPath $home\desktop\webagent.zip

$base_path = "$home\downloads"
$exclude_dir_files = @("$base_path\tmp\*",
  "$base_path\log\*",
  "*.tmp",
  "*.log"
)
 
ls -Recurse -Exclude $exclude_dir

Example of using -Exclude and additional regex filtering with -notmatch operator. This is useful for excluding folders.

$exclude = @("*.log", "*.tmp", "log*.txt*")
$files = ls -Recurse -Exclude $exclude
$files = $files | where {$_.FullName -notmatch ".*\\logs"}
Compress-Archive -Path $files -DestinationPath $home\desktop\webagent.zip

• Use the -File or -Directory option of Get-ChildItem to list on those items.

$exclude = @("*.log", "*.tmp", "log*.txt*")
$files = ls -File -Recurse -Exclude $exclude
Compress-Archive -Path $files -DestinationPath $home\desktop\webagent.zip

Example

Get-ChildItem -Recurse *.config | Select-String "foo" -List | Select Path

New-Item -force $env:temp\foo\foo.txt

Example

Compress-Archive -Path .\* -DestinationPath $env:userprofile\desktop\webapp1.zip

Example

$files = ls -Path .\* -Exclude @("*.tmp", "*.log")
Compress-Archive -Path $files -DestinationPath $env:userprofile\desktop\webapp1.zip

$files = ls -Recurse | Where-Object {$_.FullName -notlike "*log*"}
Compress-Archive -Path $file -DestinationPath $env:userprofile\desktop\webapp1.zip

List contents of archive

$archive = [System.IO.Compression.ZipFile]::OpenRead("$env:userprofile\downloads\archive.zip")
 
$archive.Entries | Select-Object -Property FullName

Unzip zip archives contained in another zip archive.

Expand-Archive -DestinationPath .\zips '.\all_reports.zip'
ls .\zips\ | % {Expand-Archive -DestinationPath $env:temp $_.FullName}

while ((Test-Path "$env:temp\mg-$suffix") -ne $false) {
    $suffix += 1
}
 
mkdir "$env:temp\mg-$suffix"

$names = @("alpha", "beta", "gamma")
 
$name = 0
 
while ($name -lt $names.Count) {
    if ((Test-Path "$env:temp\$names[$name]") -eq $false) {
        break
    }
 
    $name += 1

    $name = 0
