How can I symlink a file in Linux?
Question
I want to make a symbolic link in Linux. I have written this Bash command where the first path is the folder I want link into and the second path is the compiled source.
ln -s '+basebuild+'/IpDome-kernel/kernel /home/build/sandbox/gen2/basebuild/IpDome-kernel/kernal
Is this correct?
Accepted Answer
To create a new symlink (will fail if symlink exists already):
ln -s /path/to/file /path/to/symlink
To create or update a symlink:
ln -sf /path/to/file /path/to/symlink

(Because an ASCII picture is worth a thousand characters.)
An arrow may be a helpful mnemonic, especially since that's almost exactly how it looks in Emacs' dired.
And big picture so you don't get it confused with the Windows' version
Linux:
ln -s target <- linkName
Windows:
mklink linkName -> target
You could also look at these as
ln -s "to-here" <- "from-here"
mklink "from-here" -> "to-here"
The from-here should not exist yet, it is to be created, while the to-here should already exist (IIRC).
(I always get mixed up on whether various commands and arguments should involve a pre-existing location, or one to be made.)
EDIT: It's still sinking in slowly for me; I have another way I've written in my notes.
ln -s (target exists) (link is made)
mklink (link is made) (target exists)
