skua-tools

file, dos2unix, unix2dos and clear for Skua Bash, the bash-compatible shell bundled with Skua on Windows. Git Bash ships these (libmagic file 5.4x, dos2unix 7.x) and coding agents use them, for example git ls-files | xargs file to see line endings. No existing Rust implementation gave Git Bash's output, so these are small native programs written for that output.

• file: text (ASCII, UTF-8, UTF-8 with BOM, ISO-8859, extended ASCII; CRLF/CR/LF terminators, no terminators, very long lines, escape sequences), scripts by #! (sh, bash, python, node, perl, ...), JSON, XML, HTML, PE/ELF executables, PNG, GIF, JPEG, PDF, archives, empty, directory, symbolic links; anything else is data. Options -b -L -h -i -N -F -f --mime-type --mime-encoding. Not done: libmagic's source-language guesses (C source), gzip header details.

• dos2unix / unix2dos (one program; the name picks the direction): in place, -n IN OUT, stdin to stdout, -q -k -f -b -r -m, binary files skipped, dos2unix 7.x messages.

• clear: Git Bash's ncurses clear (\e[H\e[2J\e[3J for xterm-like terminals, -x, -T, cygwin/screen/dumb, the same errors); names Git Bash's terminfo lacks are cleared like xterm.
