Create symlinks with ln -s /target /linkname. A symlink is a pointer — deleting the link does not affect the target. rm removes just the link. Used in versioned deployments where 'current' points to the active release.
Symbolic Links
# Create symlink
ln -s /var/www/html /home/alice/www
# Hard link
ln original.txt hardlink.txt
# Check symlink target
ls -la www
# lrwxrwxrwx 1 alice alice 13 ... www -> /var/www/html
# Remove symlink
rm www # removes link, not target
