### Regex in operands

"ab11* 'foo'" -notmatch '^ab[0-2](d+)*s+''(w+)\'''
'ab11* "foo"' -match "^ab[0-2]$(2 - 1)*s+$($null)$null`"foo\`""
'2007-9-23' -replace 'b(d{2,4})-([01]?d)-([012]?d)b', '$3/$2/$1'

### Regex in here strings

$re = @'
#REGEX Id and Name
#(?<Id>d+)           # #number
s+                    # spaces
(?<Name>[_a-zA-Z]w*)  # name
'@

# how to use such a pattern:
New-Object Regex $re, 'IgnorePatternWhitespace'

### SQL in here strings

@'
--SQL single quoted
SELECT Data1, COUNT(1)
FROM Table1
WHERE Data1 = '$literal'
GROUP BY Data1
'@

@"
--SQL double quoted
SELECT Data1, COUNT(1)
FROM $Table
WHERE $x = '$variable'
GROUP BY Data1
"@

Synopsis

The task of iterating through all local files may be not straightforward if there are several drives including removable, network or substituted drives and NTFS reparse points directories. Get-Drive.ps1 and Get-File.ps1 used together may help: Get-Drive.ps1 returns only local physical drives, Get-File.ps1 excludes reparse points.

---

Examples

# calculate total available free space in GB
(Get-Drive | Measure-Object AvailableFreeSpace -Sum).Sum/1GB

# get paths of all local .bak files
Get-File \ *.bak -Name

Get-Drive.ps1

##
## Author   : Roman Kuzmin
## Synopsis : Get physical drives
##
## Returns System.IO.DriveInfo objects
##
## *) removable, network and subst drives are excluded.
##

$subst = [string](subst)
foreach($d in [System.IO.DriveInfo]::GetDrives()) {
    if ($d.DriveType -eq 'Fixed' -and $subst -notlike "*$($d.Name):*") {
        $d
    }
}

---

Get-File.ps1

##
## Author   : Roman Kuzmin
## Synopsis : Get all files
##
## Returns System.IO.FileInfo objects or full names.
## -Root: root directory(s); single \ or // denotes all physical drives.
## -Filter: simple file system filter.
## -Name: return full names as strings.
##
## *) requires Get-Drive.ps1.
## *) access errors are silently ignored.
## *) hidden and system files are included.
## *) reparse points directories are excluded.
##

    [string[]]$Root = '.',
