[SOLVED] find-switch-to-pop-up pseudoterminal

listmik · 03-12-2012, 02:05 PM

Hi,

first post, hello all.

i usually have dozens of xterminal windows open, on several workspaces. i know about the tty command and /dev/pts/X devices.

occasionally i need to terminate a process, running in lets say /dev/pts/14.

i don't want to switch through all my terminals, to find /dev/pts/14.

is there a procedure/command or so, which pops up or brings to foreground or switches to a given pts.

Thanks for your answers
mik

Greetingz!

Find processes tied to 'pts/14'

Code:

ps -ef | grep 'pts/14'

Then from any terminal, just 'kill PID#' (where PID# is the Process Identification number of the process you wanted to kill)
EDIT: If you're trying to kill the xterm window that's using 'pts/14', then look for the shell running it ( -sh, -bash, -ksh ) and kill that.

Hi,

thanks, not exactly what i need. i need to find/locate the terminal window which represents pts/14, for e.g. listing all backgroundjobs, running in this bash session.

is there a command which brings a given pts to foreground and switches to the corresponding workspace?

Thanks.

I'm not aware of any such command, though it would be specific to either the Window Manager you're using (GNOME, KDE, FluxBox, etc) or the Terminal Emulator (Konsole, Gnome Terminal, xterm, etc).

Never seen a command that did anything like that. Closest would be just Alt-Tab'ing around till you found a Terminal with 'pts/##' in the title.

How to Get the Terminal Number in an Xterm Window's Title
You could add the following to your shell's start-up file (.kshrc, .bashrc, .bash_profile, .profile, etc).
This is not just 'drop-in' code, only an example of how you would get the 'pts/#' in the title of a Terminal.
(Note that my .kshrc is about 700 lines long, and various things get collected/defined, then wind up in my Title)

Code:

TTY=$( /usr/bin/tty )   # Stores the full name of the TTY
TTY_DEV=${TTY##*/dev/}  # Cuts-out the "/dev/" prefix, which leaves "pts/0", "console", or "ttyUSB0"
TITLE="${TTY_DEV} "     # Here we could put other env vars that we want to display in a terminal's title....
print "\033]0;${TITLE}\007\c"  # Actually changes the Terminal's title.

Thank you very much, for your answer.

I'll keep on searching, and post back any results.

you need to write a script to do that.
first locate the shell opened that terminal and than find parent process (that is the terminal emulator hopefully) and then you can send a signal to it.
remember, you cannot bring a pts to the foreground but a terminal window.

you may find this tool useful to switch:

@pan64

if i open a terminal window (gnome-terminal) which has let's say PID 12000 and runs in let's say pts5, and then open a second one, this runs in pts6. both share the same PPID (12000). there is only one gnome-terminal process with two childs; the two instances of bash, running in different pts. so i cannot use the PID of gnome-terminal to focus a special terminal window.

... wmctrl: BINGO

AFAIK wmctrl cannot focus a window directly by either PID odr pts number, but:

setting PS1 to "\[\e]0;[\u@\h:\l \W]\\$ \a\][\u@\h:\l \W]\\$" puts the pts number of my terminalwindow in the windowtitle (...\l...), and with wmctrl -a :6 i can focus a window, which has the substring :6 (the pts number) in its title.

issue solved for me, thank you all for your replies

correction, just to clear things up:

... if i open a terminal window (gnome-terminal) which has let's say PID 12000 and runs in let's say pts5, and then open a second one, this runs in pts6 ...

the gnome-terminal process itself is not connected to pts5, it is the bash process, which will be automatically started by gnome-terminal, which runs in pts5.

all other statements are correct, and work for me. thanks.
