MOUNT.VBOXSF(8)

✨ NAME ✨

mount.vboxsf — the x86 virtualization solution, aka the lil buddy that lets your guest peek at your host's shared folders 💖

---

🦋 SYNOPSIS 🦋

mount.vboxsf [OPTIONS] NAME MOUNTPOINT

---

💅 DESCRIPTION 💅

Okay bestie, here's the vibe: this mounts the VirtualBox shared folder NAME from the host system over to MOUNTPOINT. That's the whole job, and it does it iconically.

Here's the flag lineup, no cap:

• -w — mount the shared folder writable (this is the default, so it's the main character unless you say otherwise) ✍️
• -r — mount the shared folder read-only (look but don't touch energy 🔒)
• -n — do not create an mtab entry
• -s — sloppy parsing, ignore unrecognized mount options (lowkey unbothered ✨)
• -o OPTION[,OPTION...] — use the mount options specified

Available mount options are:

• rw — mount writable (again, the default 💅)
• ro — mount read only
• uid=UID — set the default file owner user id to UID
• gid=GID — set the default file owner group id to GID
• ttl=MILLIESECSONDS — set the "time to live" for both the directory cache and inode info. -1 for kernel default, 0 disables it. ⏳
• dcachettl=MILLIES — set the "time to live" for the directory cache, overriding the ttl option. Ignored if negative.
• inodettl=MILLIES — set the "time to live" for the inode information, overriding the ttl option. Ignored if negative.
• maxiopages=PAGES — set the max host I/O buffers size in pages. Uses default if zero.
• dirbuf=BYTES — set the directory enumeration buffer size in bytes. Uses default size if zero.
• cache=MODE — set the caching mode for the mount. Allowed values are:
  • default: use the kernel default (strict)
  • none: no caching; may experience guest side coherence issues between mmap and read.
  • strict: no caching, except for writably mapped files (for guest side coherence)
  • read: read via the page cache; host changes may be completely ignored
  • readwrite: read and write via the page cache; host changes may be completely ignored and guest changes takes a while to reach the host
• dmode=MODE — override the mode of all directories to (octal) MODE
• fmode=MODE — override the mode of all regular files to (octal) MODE
• umask=UMASK — set the umask to (octal) UMASK
• dmask=UMASK — set the umask applied to directories only
• fmask=UMASK — set the umask applied to regular files only
• iocharset CHARSET — use the character set CHARSET for I/O operations (default set is utf8) 🌈
• convertcp CHARSET — convert the folder name from CHARSET to utf8

Less common used options:

• noexec, exec, nodev, dev, nosuid, suid

fr fr, if you're reaching for those last ones you already know what you're doing 🫶
