Ubuntu – Switch encoding of terminal with a command

command lineencodingremote accessssh

One of the servers I quite often ssh to uses western encoding instead of utf-8 (and there's no way I can change that).

I've started writing a bash script to connect to this server, so I won't have to type out the entire address every time, but I would like to improve this script so it also changes the encoding of the terminal window correctly.

The change I need to do can be performed using the mouse by navigating to "Terminal"->"Set Character Encoding…"->"Western (ISO-8859-1)". Is there a terminal command that does the same thing, for the current terminal window/screen?

To clarify:
I'm not interested in ways of switching the locale of the system on the remote site – that system is administered by someone else, and I have no idea what stuff might depend on the latin-1 encoding there. What I want to do is to let this terminal window on my side switch character encoding to the above mentioned, in the same way I can do with my mouse and the menus.

You are looking for luit which is designed for this purpose:

$ luit -encoding ISO-8859-1 ssh remote.host

It will convert the output of the ssh command to UTF-8 so you don’t need to change the encoding of the terminal.

How to Find Out Who is Using the Physical Console

I'm afraid I can't give you a specific answer (because I don't know the tech well), but I believe you can find it out using D-Bus and ConsoleKit.

For example, when I switch from X to a VT and back, I get this listening on dbus-monitor:

$ dbus-monitor --system | grep ConsoleKit
signal sender=:1.16 -> dest=(null destination) serial=19039 path=/org/freedesktop/ConsoleKit/Session2; interface=org.freedesktop.ConsoleKit.Session; member=ActiveChanged
signal sender=:1.16 -> dest=(null destination) serial=19040 path=/org/freedesktop/ConsoleKit/Seat1; interface=org.freedesktop.ConsoleKit.Seat; member=ActiveSessionChanged
signal sender=:1.16 -> dest=(null destination) serial=19041 path=/org/freedesktop/ConsoleKit/Session2; interface=org.freedesktop.ConsoleKit.Session; member=ActiveChanged
signal sender=:1.16 -> dest=(null destination) serial=19042 path=/org/freedesktop/ConsoleKit/Seat1; interface=org.freedesktop.ConsoleKit.Seat; member=ActiveSessionChanged
   string "/org/freedesktop/ConsoleKit/Session2"

Specifically, you could use the GetActiveSession method. Here's how with dbus-send (may require sudo):

$ dbus-send --system --type=method_call --print-reply --dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Seat1 org.freedesktop.ConsoleKit.Seat.GetActiveSession

Then, depending on your application, you'll want to check out the returned object's properties, which should be an object path to a Session.

Ubuntu – Convert Text File Encoding

These Windows files with Persian text are encoded in Windows-1256. So it can be deciphered by command similar to OP tried, but with different charsets. Namely:

~~recode Windows-1256..UTF-8 <Windows_file.txt > UTF8_file.txt~~
(denounced upon original poster’s complaints; see comments)

iconv -f Windows-1256 Windows_file.txt > UTF8_file.txt

This one assumes that the LANG environment variable is set to a UTF-8 locale. To convert to any encoding (UTF-8 or otherwise), regardless of the current locale, one can say:

iconv -f Windows-1256 Windows_file.txt -t ${output_encoding} > ${output_file}

Original poster is also confused with semantic of text recoding tools (recode, iconv). For source encoding (source.. or -f) one must specify encoding with which the file is saved (by the program that created it). Not some (naïve) guesses based on mojibake characters in programs that try (but fail) to read it. Trying either ISO-8859-15 or WINDOWS-1252 for a Persian text was obviously an impasse: these encodings merely do not contain any Persian letter.
