Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.
The ln command is a standard Unix command utility used to create a hard link or a symbolic link (symlink) to an existing file or directory. [1] The use of a hard link allows multiple filenames to be associated with the same file since a hard link points to the inode of a given file, the data of which is stored on disk.
The ln shell command normally uses the link [7] system call, which creates a hard link. When the ln -s flag is specified, the symlink() system call is used instead, creating a symbolic link. Symlinks were introduced in 1982 in 4.1a BSD Unix from U.C. Berkeley. [8] The following command creates a symbolic link at the command-line interface (shell):
Although Windows does not provide convenient tools to create it, Explorer supports a "folder link" or "shell link folder": a folder with the system attribute set, containing a hidden "desktop.ini" (folder customization) file which tells Explorer to look in that same folder for a "target.lnk" shortcut file pointing to another folder.
