+ FIles transferred over SHell protocol (V 0.0.3)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This protocol was designed for transferring files over a remote shell
+connection (rsh and compatibles). It can be as well used for transfers over
+rsh, and there may be other uses.
+
+Client sends requests of following form:
+
+#FISH_COMMAND
+equivalent shell commands,
+which may be multiline
+
+Only fish commands are defined here, shell equivalents are for your
+information only and will probably vary from implementation to
+implementation. Fish commands always have priority: server is
+expected to execute fish command if it understands it. If it does not,
+however, it can try the luck and execute shell command.
+
+Since version 4.7.3, the scripts that FISH sends to host machines after
+a command is transmitted are no longer hardwired in the Midnight
+Commander source code.
+
+First, mc looks for system-wide set of scripts, then it checks whether
+current user has host-specific overrides in his per-user mc
+configuration directory. User-defined overrides take priority over
+sytem-wide scripts if they exist. The order in which the directories are
+traversed is as follows:
+
+ /usr/libexec/mc/fish
+ ~/.local/share/mc/fish/<hostname>/
+
+Server's reply is multiline, but always ends with
+
+### 000<optional text>
+
+line. ### is prefix to mark this line, 000 is return code. Return
+codes are superset to those used in ftp.
+
+There are few new exit codes defined:
+
+000 don't know; if there were no previous lines, this marks COMPLETE
+success, if they were, it marks failure.
+
+001 don't know; if there were no previous lines, this marks
+PRELIMinary success, if they were, it marks failure
+
+ Connecting
+ ~~~~~~~~~~
+Client uses "echo FISH:;/bin/sh" as command executed on remote
+machine. This should make it possible for server to distinguish FISH
+connections from normal rsh/ssh.
+
+ Commands
+ ~~~~~~~~
+#FISH
+echo; start_fish_server; echo '### 200'
+
+This command is sent at the beginning. It marks that client wishes to
+talk via FISH protocol. #VER command must follow. If server
+understands FISH protocol, it has option to put FISH server somewhere
+on system path and name it start_fish_server.
+
+#VER 0.0.2 <feature1> <feature2> <...>
+echo '### 000'
+
+This command is the second one. It sends client version and extensions
+to the server. Server should reply with protocol version to be used,
+and list of extensions accepted.
+
+VER 0.0.0 <feature2>
+### 200
+
+#PWD
+pwd; echo '### 200'
+
+Server should reply with current directory (in form /abc/def/ghi)
+followed by line indicating success.
+
+#LIST /directory
+ls -lLa $1 | grep '^[^cbt]' | ( while read p x u g s m d y n; do echo "P$p $u.$g
+S$s
+d$m $d $y
+:$n
+"; done )
+ls -lLa $1 | grep '^[cb]' | ( while read p x u g a i m d y n; do echo "P$p $u.$g
+E$a$i
+dD$m $d $y
+:$n
+"; done )
+echo '### 200'
+
+This allows client to list directory or get status information about
+single file. Output is in following form (any line except :<filename>
+may be omitted):
+
+P<unix permissions> <owner>.<group>
+S<size>
+d<3-letters month name> <day> <year or HH:MM>
+D<year> <month> <day> <hour> <minute> <second>[.1234]
+E<major-of-device>,<minor>
+:<filename>
+L<filename symlink points to>
+<blank line to separate items>
+
+Unix permissions are of form X--------- where X is type of
+file. Currently, '-' means regular file, 'd' means directory, 'c', 'b'
+means character and block device, 'l' means symbolic link, 'p' means
+FIFO and 's' means socket.
+
+'d' has three fields: month (one of strings Jan Feb Mar Apr May Jun
+Jul Aug Sep Oct Nov Dec), day of month, and third is either single
+number indicating year, or HH:MM field (assume current year in such
+case). As you've probably noticed, this is pretty broken; it is for
+compatibility with ls listing.
+
+#RETR /some/name
+ls -l /some/name | ( read a b c d x e; echo $x ); echo '### 100'; cat /some/name; echo '### 200'
+
+Server sends line with filesize on it, followed by line with ### 100
+indicating partial success, then it sends binary data (exactly
+filesize bytes) and follows them with (with no preceding newline) ###
+200.
+
+Note that there's no way to abort running RETR command - except
+closing the connection.
+
+#STOR <size> /file/name
+> /file/name; echo '### 001'; ( dd bs=4096 count=<size/4096>; dd bs=<size%4096> count=1 ) 2>/dev/null | ( cat > %s; cat > /dev/null ); echo '### 200'
+
+This command is for storing /file/name, which is exactly size bytes
+big. You probably think I went crazy. Well, I did not: that strange
+cat > /dev/null has purpose to discard any extra data which was not
+written to disk (due to for example out of space condition).
+
+[Why? Imagine uploading file with "rm -rf /" line in it.]
+
+#CWD /somewhere
+cd /somewhere; echo '### 000'
+
+It is specified here, but I'm not sure how wise idea is to use this
+one: it breaks stateless-ness of the protocol.
+
+Following commands should be rather self-explanatory:
+
+#CHMOD 1234 file
+chmod 1234 file; echo '### 000'
+
+#DELE /some/path
+rm -f /some/path; echo '### 000'
+
+#MKD /some/path
+mkdir /some/path; echo '### 000'
+
+#RMD /some/path
+rmdir /some/path; echo '### 000'
+
+#RENAME /path/a /path/b
+mv /path/a /path/b; echo '### 000'
+
+#LINK /path/a /path/b
+ln /path/a /path/b; echo '### 000'
+
+#SYMLINK /path/a /path/b
+ln -s /path/a /path/b; echo '### 000'
+
+#CHOWN user /file/name
+chown user /file/name; echo '### 000'
+
+#CHGRP group /file/name
+chgrp group /file/name; echo '### 000'
+
+#INFO
+...collect info about host into $result ...
+echo $result
+echo '### 200'
+
+#READ <offset> <size> /path/and/filename
+cat /path/and/filename | ( dd bs=4096 count=<offset/4096> > /dev/null;
+dd bs=<offset%4096> count=1 > /dev/null;
+dd bs=4096 count=<offset/4096>;
+dd bs=<offset%4096> count=1; )
+
+Returns ### 200 on successful exit, ### 291 on successful exit when
+reading ended at eof, ### 292 on successfull exit when reading did not
+end at eof.
+
+#WRITE <offset> <size> /path/and/filename
+
+Hmm, shall we define these ones if we know our client is not going to
+use them?
+
+you can use follow parameters:
+FISH_FILESIZE
+FISH_FILENAME
+FISH_FILEMODE
+FISH_FILEOWNER
+FISH_FILEGROUPE
+FISH_FILEFROM
+FISH_FILETO
+
+NB:
+'FISH_FILESIZE' used if we operate with single file name in 'unlink', 'rmdir', 'chmod', etc...
+'FISH_FILEFROM','FISH_FILETO' used if we operate with two files in 'ln', 'hardlink', 'mv' etc...
+'FISH_FILEOWNER', 'FISH_FILEGROUPE' is a new user/group in chown
+
+also flags:
+FISH_HAVE_HEAD
+FISH_HAVE_SED
+FISH_HAVE_AWK
+FISH_HAVE_PERL
+FISH_HAVE_LSQ
+FISH_HAVE_DATE_MDYT
+
+That's all, folks!
