SD Commands 

CMD> sdinfo                  # SD card type, size, usage
CMD> sdls [path]             # list directory (default: current)
CMD> cd <path|..>            # change working directory
CMD> cat <path>              # read file — scrollable viewer
CMD> edit <path>             # nano-style text editor (alias: ed)
CMD> rm <path>               # delete file
CMD> rm -d <dir>             # delete directory + all contents (asks y/N)
CMD> sdformat [init]         # format SD to FAT32 (WARNING: destroys all data)

Notes

  • Paths are relative to your current directory (set with cd) — no leading / needed. cat creds.csv, edit wordlist.txt, rm -d oldtool all work from wherever you are. Absolute paths (/apps/...) are also accepted.
  • cat: loads up to 400 lines, strips Windows \r, scrollable with a cyan scrollbar. Trackball up/down scrolls.
  • edit / ed: on-device text editor for SD files (handy for tweaking wordlists, captive-portal HTML, configs in the field). Opening a path that doesn’t exist starts a new buffer that’s written on the first save — and any missing parent folders are created automatically (e.g. ed notes/today.txt works even if notes/ doesn’t exist yet). Loads up to 500 lines; a larger file opens read-only so it can’t be truncated on save.
    • Type to insert, Backspace to delete (hold to auto-repeat), Enter splits the line (with auto-indent — the new line keeps the current line’s leading whitespace).
    • Trackball moves the cursor (Up/Down/Left/Right, wrapping across line ends). Roll fast to accelerate — a quick roll jumps several lines/chars at once, so paging through big files is fast.
    • Click opens the command menu: Save · Save As · Find · Go to line · Top · Bottom · Undo · Cut line · Paste line · Exit. (There is no q quit — q is a normal character — so exit via the menu.)
    • Undo reverts the last change (single level — coalesced per typing/delete run).
    • Exiting with unsaved changes prompts: [s] save & exit, [d] discard, click = cancel.
  • rm: deletes a file with no confirmation. rm -d <dir> removes a directory and everything inside it (recursive) — this one asks y/N first, and refuses to delete the card root or the current working directory (use cd out first). Deleting a plain directory without -d is refused.
  • sdformat: prompts for confirmation before formatting. sdf init formats and re-creates the full directory structure in one step.
  • Tab-complete: works for sdls, cd, cat, edit, and rm — press ' to complete paths. rm now completes both files and directories (so you can tab into nested folders and target a dir for rm -d).
