These below can be expansions for the Linux File System, (originally taken from here)
All the system directories were kept to three letters, and all of the names are abbreviations — none are acronyms.
- /bin = binary
- /lib = library
- /var = variable
- /usr = user
- /tmp = temporary
- /adm = administrative (now found in /var/adm)
- /log = logs (now found in /var/log)
- /etc = et cetera
- “editable text configuration” is a backronym.
- /etc is et cetera.
Later additions followed the same pattern:
- /net = network
- /mnt = mount
Interesting , isnt it 🙂
