ash	PowerShell	Description
Scripting Basics
Put a “shebang” at the beginning of the file: `<br>#!/bin/bash` Change permissions on script file to allow execution.	Give the file a ps1 extension. For downloaded scripts, unblock the file under file properties in Windows Explorer.	Steps for making scripting files run. In PowerShell, the first time you do scripting, you will need to set the appropriate security settings: run PowerShell as administrator and type `set-executionpolicy remotesigned`.
`source (or) .`	`.`	shell built-in: execute the commands in a file
`echo _String_`	`echo _String_` (or) `Write-Host _String_`	Prints String to the screen. In PowerShell, `Write-Host` forces the output to the screen instead of being a return value.
`_var_=0` (No spaces around =)	`$_var_ = 0`	Creates a variable $var. In BASH, do not put whitespace around the equals sign, and do not use a $ in the variable assignment.
`let _var_=$_var_+5` (or) `<br>_var_=$(( $_var_ + 5 ))`	`$_var_ += 5`	Add 5 to $var
`# _comment_`	`# _comment_`	A comment
Strings
`= !=`	`-eq -ne -ceq -cne`	String comparisons. In BASH, be sure the strings litereals are in quotes.
`"" \| gm`		Get a list of non-static string members
`[string] \| gm -static`		Get a list of static string members
`${_string_#_text_to_remove_}`	`_string_.TrimStart("_characters_")`	Removes the specified characters/text from the beginning of the string.
`${_string_%_text_to_remove_}`	`_string_.TrimEnd("_characters_")`	Removes the specified characters/text from the end of the string. Suppose $fnm == helloThere.txt; then ${fnm%.???} is helloThere
Pattern Matching
`grep`	`select-string`	print lines matching a pattern
`sed`	`-replace`	performs string transformations
Booleans and Conditions
`true false`	`$true $false`	Boolean literals
`-lt -gt -le -ge -eq -ne`	`-lt -gt -le -ge -eq -ne`	Arithmetic relational operators
	`-like`	True if a string matches a wildcard pattern
	`-match`	True if a string matches a regular expressions
	`Where-Object { _condition_ }`	Used to filter input by a condition. Remember that $_ refers to the current object being tested.
`-z $_var_`	`$_var_ -eq $null`	True if $var is null
`-n $_var_`	`$_var_ -ne $null`	True if $var is not null (contains one or more characters)
`-o -a`	`-or -and`	Logical or and and
`-e _file_`	`Test-Path _file_`	True if file exists.
`! -e _file_`	`! (Test-Path _file_)`	True if file does not exist.
`-d _file_`	`_file_.PSISContainer`	True if file is a directory. In PowerShell, if file is not a file variable, be sure to get the file object first with `gi`.
`-s _file_`		True if file exists and has a size greater than zero.
`_file1_ -nt _file2_`		True if file1 is newer (according to modification date) than file2
`_file1_ -ot _file2_`		True if file1 is older (according to modification date) than file2
Control Structures
`if [ _condition_ ] <br>then <br>_codeblock_ <br>fi`	`if (_condition_) { <br>_codeblock_ <br>}`	If statement. In BASH, be sure to leave a space between the condition and the bracket.
`if [ _condition_ ] <br>then <br>_codeblock_ <br>elif [ _condition_ ] <br>then <br>_codeblock_ <br>else <br>_codeblock_ <br>fi`	`if (_condition_) { <br>_codeblock_ <br>} <br>elseif (_condition_) { <br>_codeblock_ <br>} <br>else { <br>_codeblock_ <br>}`	If – else if – else statement
`var=0 <br>while [ $var -lt 10 ] <br>do <br>echo $var <br>var=$(( $var + 1 )) <br>done`	`$var = 0 <br>while ($var -lt 10) { <br>echo $var <br>$var++ <br>}`	Prints numbers 0 through 9.
`for ((i=0; i < 10; i++)) do <br>echo $i <br>done`	`for ($i=0;$i -lt 10; $i++) <br>{ <br>echo $i <br>}`	Prints numbers 0 through 9.
`for _var_ in $_array_ <br>do <br>_codeblock_ <br>done`	`foreach ($_var_ in $_array_) <br>{ <br>_codeblock_ <br>}`	For each loop
`continue break`	`continue break`	Loop controls: continue stops current loop iteration and begins the next; break exits the loop currently being executed.
`basename _file_`	`_file_.name`	The name of file without the path. In PowerShell, remember to first get the file object.
`dirname _file_`	`_file_.directoryname`	The name directory file is in. In PowerShell, remember to first get the file object.
`stat -c%s $_file_` (or) `$(stat -c%s $_file_)`	`_file_.length`	The number of bytes in file. In PowerShell, remember to first get the file object.
	`_file_.LastWriteTime`	The last modified time for file. Remember to first get the file object.
_files_=`ls` (or) `_files_=$(ls)` (or) `_files_=*`	`$_files_ = Get-Item *`	Store a list of the files in the current working directory in $files. In PowerShell, check out the -exclude flag as well as the Get-ChildItem cmdlet.
`\| > >> 2> 2>>`	`\| > >> 2> 2>>`	Piping, output and error redirection. In BASH, output redirected to `/dev/null` is gone. In PowerShell, output redirected to `$null` is gone.
`_printArg_() <br>{ <br>_echo_ $1 <br>}`	`function _printArg_ <br>{ <br>param ($_p1_) <br>_echo $p1_ <br>}`	function to print the first argument to the screen.
`_return_five_() <br>{ <br>return _5_ <br>}<br><br>` `_return_five_ <br>echo $?`	`function _return_five_ <br>{ <br>echo _5_` (or) `return _5_ <br>}<br><br>` `$_value_ = _return_five_ <br>echo $_value_`	Function returns 5, which is printed after the function call. In PowerShell, any output in a function that is not caught is returned. The return statement merely ends the function. The return value of a BASH function is stored in the variable $?.

  作为一名linux管理员有时使用powershell是有些无所适从的，因为一些命令用习惯了而powershell没有的话就需要gow，cygwin的辅助。
  当然powershell依然是强大和值得推崇的。
