![]() one is where you can remove existing softlink with rm and again create new softlink with ln -s command.You can modify the softlink created once in one of the two ways as below in Linux Ln: creating symbolic link `': File exists So, deleting and rebuilding the symlink is a bit more work but also a bit saver: rm thesymlink & ln -s thesymlink Lrwxrwxrwx 1 mbucher Of course this is intended, but usually mistakes occur. ĭrwxr-xr-x 18 mbucher -rw-r-r- 1 mbucher lrwxrwxrwx 1 mbucher -> thesymlink ĭrwxr-xr-x 18 mbucher -rw-r-r- 1 mbucher -rw-r-r- 1 mbucher lrwxrwxrwx 1 mbucher www-data 11 May 25 15:26 thesymlink -> ln -s -f thesymlink ls -laĭrwxr-xr-x 2 mbucher www-data 4096 May 25 15:28. Using the -f / -force Method provides a risk to lose the file if you mix up source and target: ls -laĭrwxr-xr-x 2 mbucher www-data 4096 May 25 15:27. Just a warning to the correct answers above: The permissions are always 0777 (read, write, and execute for all user On Linux, the permissions of a symbolic link are not used in any operations The last access and last modification timestamps of a symbolic link can beĬhanged using utimensat(2) or lutimes(3). When the link is being removed or renamed in a directory that has the sticky The only time that the ownership of a symbolic link matters is The owner and group of an existing symbolic link can be changed using ![]() Regarding the assertion that the actual owner and group are immaterial, symlink(7) on Linux says that there is a case where it is significant: On some filesystems, the target of the symlink is stored in the inode itself (in place of the block list) if it is short enough this is determined at the time it is created. However this will not reuse the original inode. This is better than explicitly unlinking because rename is atomic, so you can be assured that the link will always point to either the old or new target. (or use the equivalent symlink and rename calls). It is not necessary to explicitly unlink the old symlink. Note that in the above, both mv -T and strace are Linux-specific.Įditor's note: This is how Capistrano has done it for years now, ever since ~2.15. Below, the output of strace on my linux box proving it: $ strace -o /tmp/output.txt ln -s -f. ![]() profileĮDIT: As the OP pointed out in a comment, using the -force option will make ln perform a system call to unlink() before symlink(). Lrwxrwxrwx 1 pascal pascal 8 17:12 test ->. Ln: creating symbolic link `test': File exists Lrwxrwxrwx 1 pascal pascal 7 17:12 test ->. Actually, you can overwrite a symlink and thus update the pathname referenced by it: $ ln -s.
