User Commands Mkdir ( 1 ) Mkdir – Make Directories Mkdir [-M Mode User Commands mkdir ( 1 ) NAME mkdir – make directories SYNOPSIS mkdir [-m mode] [-p] dir... DESCRIPTION The mkdir command creates the named directories in mode 777 (possibly altered by the file mode crea- tion mask umask(1)). Standard entries in a directory (for instance, the files ".", for the directory itself, and ". .", for its parent) are made automatically. mkdir cannot create these entries by name. Creation of a directory requires write permission in the parent directory. The owner-ID and group-ID of the new directories are set to the process’s effective user-ID and group- ID, respectively. mkdir calls the mkdir(2) system call. setgid and mkdir To change the setgid bit on a newly created directory, you must use chmod g+s or chmod g-s after exe- cuting mkdir. The setgid bit setting is inherited from the parent directory. OPTIONS The following options are supported: -m mode This option allows users to specify the mode to be used for new directories. Choices for modes can be found in chmod(1). -p With this option, mkdir creates dir by creating all the non-existing parent directories first. The mode given to intermediate directories will be the difference between 777 and the bits set in the file mode creation mask. The difference, however, must be at least 300 (write and execute permission for the user). OPERANDS The following operand is supported: dir A path name of a directory to be created. USAGE See largefile(5) for the description of the behavior of mkdir when encountering files greater than or equal to 2 Gbyte ( 2 31 bytes). EXAMPLES Example 1: Using mkdir The following example: example% mkdir -p ltr/jd/jan creates the subdirectory structure ltr/jd/jan. ENVIRONMENT VARIABLES See environ(5) for descriptions of the following environment variables that affect the execution of mkdir: LC_CTYPE, LC_MESSAGES, and NLSPATH. EXIT STATUS The following exit values are returned: 0 All the specified directories were created successfully or the -p option was specified and all the specified directories now exist. >0 An error occurred.

  • Command Line Interface Specification Windows
    Command Line Interface Specification Windows Online Backup Client version 4.3.x 1. Introduction The CloudBackup Command Line Interface (CLI for short) makes it possible to access the CloudBackup Client software from the command line. The following actions are implemented: backup, delete, dir en restore. These actions are described in more detail in the following paragraphs. For all actions applies that a successful action is indicated by means of exit code 0. In all other cases a status code of 1 will be used. 2. Configuration The command line client needs a configuration file. This configuration file may have the same layout as the configuration file for the full CloudBackup client. This configuration file is expected to reside in one of the following folders: CLI installation location or the settings folder in the CLI installation location. The name of the configuration file must be: Settings.xml. Example: if the CLI is installed in C:\Windows\MyBackup\, the configuration file may be in one of the two following locations: C:\Windows\MyBackup\Settings.xml C:\Windows\MyBackup\Settings\Settings.xml If both are present, the first form has precedence. Also the customer needs to edit the CloudBackup.Console.exe.config file which is located in the program file directory and edit the following line: 1 <add key="SettingsFolder" value="%settingsfilelocation%" /> After making these changes the customer can use the CLI instruction to make backups and restore data. 2.1 Configuration Error Handling If an error is found in the configuration file, the command line client will issue an error message describing which value or setting or option is causing the error and terminate with an exit value of 1.

  • TRSDOS 6.2 to LS-DOS 6.3.0 Manual Update
    LS-DOSÔ 6.3 UPDATE FOR TRSDOSâ 6.2.X The LS-DOS 6.3 release is an upgrade for the TRSDOS 6.2 operating system. Several important changes have been made to extend and enhance the operating system and its utilities. The date ranging has been expanded to accept dates through the year 1999. Files will now carry a modification time as well as a date. The DATECONV/CMD program is provided to translate version 6.2 or earlier disks to the 6.3 style dating. The user password has been eliminated from the system. The owner password still remains. The library command ID was added to display a customer service number. Several enhancements have been made to BASIC. The new DISKCOPY/CMD program will duplicate 5" double density floppy disks. Because the LS-DOS 6.3 update is a series of enhancements to TRSDOS 6.2, the primary documentation remains the 6.2 manual and Technical Reference manual. If you have a version of TRSDOS earlier than 6.2, you can obtain the manuals from Radio Shack under the catalog numbers 26-0316 (TRSDOS Version 6 [6.2 DOS manual and disk]), 26-2110 (Model 4/4D [6.2] Technical Reference Manual), or 26-1117 (6.2 DOS manual only). This documentation should be treated as an addendum to the TRSDOS 6.2 information. LS-DOS 6.3 installation instructions Before performing the upgrade, it is recommended that you make several backup copies of the 6.3 master disk. The simplest way to do this is to boot your system using the 6.3 diskette, insert a blank diskette to receive the copy in drive 1, and type the command: DISKCOPY :0 :1 When the copy finishes, you can insert another destination diskette and make another copy.

  • Alias Manager 4
    CHAPTER 4 Alias Manager 4 This chapter describes how your application can use the Alias Manager to establish and resolve alias records, which are data structures that describe file system objects (that is, files, directories, and volumes). You create an alias record to take a “fingerprint” of a file system object, usually a file, that you might need to locate again later. You can store the alias record, instead of a file system specification, and then let the Alias Manager find the file again when it’s needed. The Alias Manager contains algorithms for locating files that have been moved, renamed, copied, or restored from backup. Note The Alias Manager lets you manage alias records. It does not directly manipulate Finder aliases, which the user creates and manages through the Finder. The chapter “Finder Interface” in Inside Macintosh: Macintosh Toolbox Essentials describes Finder aliases and ways to accommodate them in your application. ◆ The Alias Manager is available only in system software version 7.0 or later. Use the Gestalt function, described in the chapter “Gestalt Manager” of Inside Macintosh: Operating System Utilities, to determine whether the Alias Manager is present. Read this chapter if you want your application to create and resolve alias records. You might store an alias record, for example, to identify a customized dictionary from within a word-processing document. When the user runs a spelling checker on the document, your application can ask the Alias Manager to resolve the record to find the correct dictionary. 4 To use this chapter, you should be familiar with the File Manager’s conventions for Alias Manager identifying files, directories, and volumes, as described in the chapter “Introduction to File Management” in this book.
