PowerShell: List Files

List Files

List file in current directory. (dir is alias of Get-ChildItem)

# if no -path given, default to current dir
dir

list file of a given path:

dir c:/Users/xah/web/

If path contain space, need quote. [see Path Tutorial]

Wildcard in Path and Literal Path

Path can contain Wildcards * to stand for any char, zero or more times:

# list files whose name contain index
dir c:/Users/xah/web/*index*

# list files whose name ends in jpg
dir c:/Users/xah/web/*jpg

if you do not want special interpretation of path, use -LiteralPath.

# list files in a dir, dir name literally is asterisk j p g
dir -LiteralPath c:/Users/xah/web/*jpg

[see Path Tutorial]

Show Subdirectories (Recurse and Depth)

list files in current dir, and all subdirectories, any depth:

-recurse has a alias of -s

dir -recurse

-depth 1 means include children of first-level subdirectories. -depth 2 means up to second-level subdirectories, etc.

dir -depth 1

-depth 0 is same as no recurse.

# list just current dir children
dir -depth 0
