Dir syntax

Microsoft Windows 2000, XP, Vista, 7, and 8 syntax

Displays a list of files and subdirectories in a directory.

DIR [drive:][path][filename] [/A[[:]attributes]] [/B] [/C] [/D] [/L] [/N] [/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4]

Switches may be preset in the DIRCMD environment variable. Override preset switches by prefixing any switch with – (hyphen)–for example, /-W.

Dir examples

dir

Lists all files and directories in the current directory. By default the dir command lists the files and directories in alphabetic order.

dir *.exe

The above command lists any file that ends with the .exe file extension. See the wildcarddefinition for further wildcard examples.

dir *.txt *.doc

The above is using multiple filespecs to list any files ending with .txt and .doc in one command.

dir /ad

List only the directories in the current directory. If you need to move into one of the directories listed use the cd command.

dir /s

Lists the files in the directory that you are in and all sub directories after that directory, if you are at root “C:>” and type this command this will list to you every file and directory on the C: drive of the computer.

dir /p

If the directory has lots of files and you cannot read all the files as they scroll by, you can use this command and it displays all files one page at a time.

dir /w

If you don’t need file information you can use this command to list only the files and directories going horizontally, taking as little as space needed.

dir /s /w /p

This would list all the files and directories in the current directory and the sub directories after that, in wide format and one page at a time.

dir /on

List the files in alphabetical order by the names of the files.

dir /o-n

List the files in reverse alphabetical order by the names of the files.

dir /s |find “i” |more

A nice command to list all directories on the hard drive, one screen page at a time, and see the number of files in each directory and the amount of space each occupies.

dir > myfile.txt

Takes the output of dir and re-routes it to the file myfile.txt instead of outputting it to the screen.

Alias

Alias

alias

Create an alias. Aliases allow a string to be substituted for a word. An alias can be used as the first word of any simple command.

Syntax
alias [-p] [name[=value] ...]

unalias [-a] [name...]

Key
-p Print the current values

-a Remove All aliases

When arguments are supplied, an alias is defined for each name whose value is given. A trailing space in value causes the next word to be checked for alias
substitution when the alias is expanded.

If no value is given, (or with the -p option) alias will print a list of Aliases along with their current values. For each name in the argument list for which no value is supplied, the name and value of the alias is printed.

Alias returns true unless a name is given for which no alias has been defined.

name can not be `alias’ or `unalias’.

unalias can be used to remove each name from the list of defined aliases.

Alias substitution
The shell maintains a list of aliases which can be set, unset and printed by the alias and unalias commands. After a command line is parsed into simple commands the first word of each command, left-to-right, is checked to see if it has an alias. If so, the first word is replaced by the alias. If the alias contains a history reference, it undergoes History substitution (q.v.) as though the original command were the previous input line. If the alias does not contain a history reference, the argument list is left untouched.

Thus if the alias for ls were ls -l the command ls /usr would become ls -l /usr, the argument list here being undisturbed. If the alias for lookup were grep !^ /etc/passwd‘ then lookup bill would become grep bill /etc/passwd.

Aliases can be used to introduce parser metasyntax. For example, alias print ‘pr !* | lpr’ defines a command (print) which pr‘s its arguments to the line printer.

The first word of the replacement text is tested for aliases, but a word that is identical to an alias being expanded is not expanded a second
time. This means that you can alias ls to ls -F, for instance, and bash does not try to recursively expand the replacement text.

Examples

Create an alias ‘c’ that will clear the screen:
$ alias c=’clear’

Create an alias ‘ls’ that will change the default action of ls:
$ alias ls=’ls –classify’
$ ls
$ unalias ls

More aliases for ls:
$ alias la=’ls -lAXh –color=always’   #Show all, sort by extension
$ alias ls-al=’ls -al’   #fix typo missing space
$ alias l=”ls -l”
$ alias la=”ls -la”

Use alias to fix missing space typos:
$ alias cd..=’cd ..’
$
alias ..=’cd ..’

Display the working directory
$ alias .=’echo $PWD’

Prevent accidental deletions by making rm interactive:
$ alias rm=’rm -i’

Shorten apt-get installation commands:
$ alias canhaz=’sudo apt-get install’

Run firefox and open a specific website:
$ alias fftr=’/Applications/Firefox.app/Contents/MacOS/firefox-bin http://ss64.com’

Produce a custom prompt to display which machine you are on, the current folder, and the number of the current command:

   $ alias cd='cd !*; set currDir = `basename $cwd`; set currDir = `echo
"<${host}:"$currDir
" ! >"`; set prompt = "${currDir} "'
$ cd $cwd

<Mac_One:Work-folder 15 >

Making an alias permanent:

Assuming you have the BASH shell, then use your favorite text editor to edit or create a file called ~/.bash_aliases and add your alias commands.

alias is a bash built-in command.

“There are many reasons why novelists write, but they all have one thing in common – a need to create an alternative world” ~ John Fowles

In Windows I would normally be driven to either format a drive through the Disk Management console or by right-clicking on a drive in Windows Explorer and selecting the “Format…” option, but there can be advantages to formatting a driver through Command Prompt. For example if you are reformatting a drive which previously had an Operating System on the drive you can find there are System Partitions on the drive which can’t be seen in Windows Explorer and refuse to format in the Disk Management console.

Note this is only a quick guide for Formatting Drives from Command Line, there are many more options available at your disposal. For a detailed insight to the options available for the DiskPart tool visit Microsofts Technet. In the example I have formatted an external hard drive for use of file storage in a Windows Operating System environment.

In order to format a drive through Command Prompt firstly lets open the prompt.

Click Start > Run and type “CMD”, pressing Enter should open a new terminal.

Start CMD

 

We need to next start the Disk Part tool, type “DISK PART” into the Command Line and press Enter.

Start Disk Part

 

Next let’s display and identify which volume we would like to format. Type “list volume” and press Enter. You should see a list of available volumes. Identify the one which you wish to format, be careful selecting the wrong volume will spell disaster!

List Volume

 

Type “select volume <x>” and press Enter, where <x> is the volume you wish to focus on.

Select Volume

 

Type “clean” and press Enter. This removes any and all partition or volume formatting from the disk in focus.

Clean

 

Type “create partition primary” and press Enter. This creates a primary partition on the current disk. After you create the partition, the focus automatically shifts to the new partition. It is possible to create multiple partitions if you like. To do this you would add the option size=<x> where <x> is the size in megabytes (MB) you would like the partition to be. If no size is specified, like in my example, the partition continues until there is no more unallocated space.

Create Partition

 

Type “format fs=ntfs quick label=test” and press Enter. This will now perform a quick format, using a ntfs file system and labelling the drive “test”. You may wish to use the file system fat32 in place of ntfs if you would like to use the drive with other operating systems.

Format

 

Lastly type “assign letter <x>” and press Enter, where <x> is the letter you would like to assign the drive.

Assign Drive Letter

You can close the Disk Part tool and Command Prompt using the “exit” command. You should now see your freshly formatted drive in My Computer, ready to use.
