Mv moves a file that currently exists (the first argument) to a new place (the second argument) Mv /file/that/exists /location/its/moving/toĬp copies a file that currently exists (the first argument) to a new file (the second argument). If having to search or read through a man page every time isn't for you, maybe you'll have an easier time remembering that all nix commands work the same way : cp /file/that/exists /location/for/new/file You can access this via searching "man ln" in google, or just open a terminal window and type man ln and you'll get the same information. To your new link /home/build/sandbox/gen2/basebuild/IpDome-kernel/kernalįirst, there's the man page for ln.
This will indeed create a symbolic link ( -s) from the file/directory: /IpDome-kernel/kernel This is why the file-explorer is often the only program that traverses them, or programs that use the file-explorer as their file-loader.'ln -s '+basebuild+'/IpDome-kernel/kernel /home/build/sandbox/gen2/basebuild/IpDome-kernel/kernal' However all program that traverse them needed to be changed. When Short-cuts were invented, and added to MS-Windows, no change to the operating-system or file-system was needed. Whether desktop, command-line, service or other. However all existing programs suddenly gained the ability to traverse them. When sym-links were invented, it needed a change to the operating-system, and to the file-systems. However last time I checked it was poorly documented.

Do not confuse Mac short-cuts with sym-link, they are not the same. MS-Windows also has them, but are disabled by default (last time I checked). Sym-links are in all modern Unixes (UNIX, Gnu/Linux, Linux (is it is done in the kernel), MacOS, BSD, QNX). Note that for writing, it makes a difference whether you overwrite the existing file (which will act on the target) or remove the existing file and create a new file (which will leave the target intact and create a new file replacing the symlink, unless the application takes care to follow the link (many do)). Operations that act on a file from the outside, such as renaming or deleting, act on the symbolic link itself. Thus when you read or write to a file through a symbolic link, or execute a program through a symbolic link, it's as if you were accessing the target file. Operations that act on the file's content act on the target file. The target file may or may not exist, and removing, moving or creating the target file will not affect the symbolic link.
bar or just bar) if the target is given by a relative path, it's interpreted relative to the directory containing the symbolic link. The path can be absolute ( /foo/bar) or relative ( foo/bar or. potentially including a directory part as well as the name inside the directory. So I think shortcuts are not a good way to understand symbolic links and I recommend to clear your mind of the comparison with shortcuts.Ī symbolic link indicates the name of another file. I have known people to think “ok, symlinks are like shortcuts, but I don't quite understand them” up to the point when they said “oh, actually symlinks are not like shortcuts, and now I understand them”. There is a resemblance, but only up to a point.
