ln command

Synopsis

ln <target> <linkname>

Description

The ln command creates a symbolic link in the VFS. The symbolic link linkname is created pointing to target. The target string is stored as-is in the symlink and is not resolved at creation time.

The filesystem must be mounted first using mount and must support symbolic links (e.g. ext4). FAT filesystems do not support symlinks.

target: string to store as the symlink target
linkname: absolute or relative path for the new symbolic link

Example

=> mount host 0:0 /mnt
=> ln testfile.txt /mnt/link.txt
=> stat /mnt/link.txt
  File: link.txt
  Size: 12
  Type: symbolic link

Configuration

The ln command is available when CONFIG_CMD_VFS=y.

Return value

The return value $? is set to 0 (true) if the symlink was created, 1 (false) otherwise.
