  • Where's my tab completion and up-arrow behavior? (Ubuntu 10.04)

    - by pastorius
    I'm new to Linux, trying Ubuntu 10.04, preconfigured by host. When I log in (SSH) using the preconfigured account, the shell prompt is: user@hostname:~$ The up arrow scrolls through the list of recent shell commands, and tab-completion works as expected. However, when I create an account and log in (SSH) using that account, the shell prompt is simply "$", and the up arrow just prints a control character (^[[A). Can anyone tell me how to get my prompt, tab-completion, and up-arrow behavior set up? The fact that I'm getting control characters when I up-arrow makes me think that my account (or session) is in some mode I'm unfamiliar with. I know there is tab-completion code stored in bashrc that I can uncomment, but that doesn't seem to have any effect, even after logging out and logging back in. Am I in some strange mode when I SSH in with the new account, or are there just some session/account settings I need to set up, and can find information for anywhere on the Internet if I just knew what to look for?

  • Slow boot on Ubuntu 12.04

    - by Hailwood
    My Ubuntu is booting really slow (Windows is booting faster...). I am using Ubuntu a Dell Inspiron 1545 Pentium(R) Dual-Core CPU T4300 @ 2.10GHz, 4GB Ram, 500GB HDD running Ubuntu 12.04 with gnome-shell 3.4.1. After running dmesg the culprit seems to be this section, in particular the last three lines: [26.557659] ADDRCONF(NETDEV_UP): eth0: link is not ready [26.565414] ADDRCONF(NETDEV_UP): eth0: link is not ready [27.355355] Console: switching to colour frame buffer device 170x48 [27.362346] fb0: radeondrmfb frame buffer device [27.362347] drm: registered panic notifier [27.362357] [drm] Initialized radeon 2.12.0 20080528 for 0000:01:00.0 on minor 0 [27.617435] init: udev-fallback-graphics main process (1049) terminated with status 1 [30.064481] init: plymouth-stop pre-start process (1500) terminated with status 1 [51.708241] CE: hpet increased min_delta_ns to 20113 nsec [59.448029] eth2: no IPv6 routers present But I have no idea how to start debugging this. sudo lshw -C video $ sudo lshw -C video *-display description: VGA compatible controller product: RV710 [Mobility Radeon HD 4300 Series] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list rom configuration: driver=fglrx_pci latency=0 resources: irq:48 memory:e0000000-efffffff ioport:de00(size=256) memory:f6df0000-f6dfffff memory:f6d00000-f6d1ffff After loading the propriety driver my new dmesg log is below (starting from the first major time gap): [2.983741] EXT4-fs (sda6): mounted filesystem with ordered data mode.

  • gen_server with a dict vs mnesia table vs ets

    - by pablo
    Hi, I'm building an erlang server. Users sends http requests to the server to update their status. The http request process on the server saves the user status message in memory. Every minute the server sends all messages to a remote server and clear the memory. If a user update his status several times in a minute, the last message overrides the previous one. It is important that between reading all the messages and clearing them no other process will be able to write a status message. What is the best way to implement it? gen_server with a dict. The key will be the userid. dict:store/3 will update or create the status. The gen_server solves the 'transaction' issue. mnesia table with ram_copies. Handle transactions and I don't need to implement a gen_server. Is there too much overhead with this solution? ETS table which is more light weight and have a gen_server. Is it possible to do the transaction in ETS? To lock the table between reading all the messages and clearing them? Thanks

  • Apache2 cgi's crash on odbc db access (but run fine from shell)

    - by Martin
    Problem overview (details below): I'm having an apache2 + ruby integration problem when trying to connect to an ODBC data source. The main problem boils down to the fact that scripts that run fine from an interactive shell crash ruby on the database connect line when run as a cgi from apache2. Ruby cgi's that don't try to access the ODBC datasource work fine. And (again) ruby scripts that connect to a database with ODBC do fine when executed from the command line (or cron). This behavior is identical when I use perl instead of ruby. So, the issue seems to be with the environment provided for ruby (perl) by apache2, but I can't figure out what is wrong or what to do about it. Does anyone have any suggestions on how to get these cgi scripts to work properly? I've tried many different things to get this to work, and I'm happy to provide more detail of any aspect if that will help.

  • Tab Completion In Emacs shell-mode SSH Sessions

    - by Sean M
    My current use pattern of emacs results in my having several shell-mode buffers open, each running an ssh session. I am running into an issue with this, though - when I try to tab-complete file names and other things in my remote session, the shell attempts to use completions available on the local machine instead of on the remote machine. For example, if the file ~/foobar exists on the local machine and ~/frob exists on the remote machine, typing in ~/f and pressing tab results in ~/foobar instead of completing correctly. If I use ssh outside of emacs and try the same thing, I get the correct completion of ~/frob instead. How can I get tab-completion to complete the way it does in normal ssh sessions ?

  • zsh completion will not work in emacs shell

    - by benhsu
    I'm learning about the more powerful tab-completion and expansion capabilities of zsh, and they don't seem to work when I run zsh under emacs with M-x shell: cat $PATH<TAB> expands the tab variable in Terminal, but in shell-mode it just beeps. I poked around the emacs environment and here's what I found: TAB (translated from ) runs the command completion-at-point, which is an interactive compiled Lisp function in `minibuffer.el'. It is bound to TAB, . (completion-at-point) Perform completion on the text around point. The completion method is determined by `completion-at-point-functions'. completion-at-point-functions is a variable defined in `minibuffer.el'. Its value is (tags-completion-at-point-function) So I'm surmising I need to add a function to completion-at-point-functions, but which one?

  • CHROOT for shell script testing

    - by Josh
    I am looking at setting up a shell script in order to properly document and automate the process I am using to setup a few servers we have. In order to test the shell script through its different stages I was thinking a CHROOT would be ideal, since I can wipe out the "virtual root" and create it on the fly. I have never used CHROOT before, however. I was just curious what are the exact steps I would need to follow to implement this process of creating a chroot (with the basic core functions that would be needed to install apache/php/etc.)? and then destroying it?

  • Ubuntu from console/command-line/shell

    - by Xolve
    Earlies linux distros though required lot of manual work they were quite good to use from commandline. If the X-server didn't start or you just want a shell to work they all supported. Network was configured by init; sound was up and ready; new devices inserted would be configured and their configureation was placed in fstab. Also there were small scripts I found on many distros which on X used windows while on console they switched to ncurses. But now this all needs GUI with a desktop manager (KDE, GNOME) for the new paradigms :'-( require GUI (NetworkManger, hal etc.). So if on just command line you have to be root, looks like they believe only geeky admins need that, and need to edit config files or type big commands. Any way so that this is easy in Ubnubtu through shell again.

  • No colors when running native windows shell application from mintty

    - by Pete
    Hi. I have installed cygwin (i'm not very experienced with it), and try to run a native windows shell application from it, (msbuild.exe which is the build tool for the .NET framework, to be exact). When I run the application from the normal cygwin bash shell, the output of the application appear as it should with the text colors that I would normally see in the windows command line. But when I execute the program from a mintty terminal, there is no coloring of the output, all text is in the default foreground color. I'm puzzled, because I would have expected the color coding to be the standard ANSI color code escape characters... Can this be fixed?

  • Unix Shell/SSH config to allow TCP port forwarding without showing a command prompt

    - by Raphael K
    I'm running a Debian Linux. I'd like to have a user account that is able to connect via SSH for TCP-forwarding only, without a command prompt. e.g the following would work (from a remote computer): ssh -D1234 user@myhost but no command prompt would appear. Using a shell like /bin/false or /sbin/nologin is too restrictive as it doesn't even allow the user to log in. A shell that only allows the "exit" or Ctrl+D commands would do the job. I know that something similar is possible to allow only SFTP, but I can't find the equivalent for TCP forwarding. Thanks

  • can't run binaries or shell scripts

    - by hyperboreean
    I am running Debian testing and I am not able to run any binary or shell script. I keep getting "No such file or directory". The umask is the default one and I haven't fooled around with the paths. Also, I am aware of this question, but it doesn't work out for me - I compiled my code on this machine and trying to run it on the same machine. Also, all of my shell scripts have the correct shebang. Any advices?

  • Booting drops to EFI shell but boots normally if exit'ed

    - by wittybear
    (first post here... I'm normally on stackoverflow) I'm booting an Intel ME 5788 board which uses EFI (a replacement for BIOS). On boot it drops out to the EFI Shell and the 'map' shows the drive as a blockdevice but there is no filesystem device mapped. If I just type 'exit' it boots normally to windows 7 and the configuration (using bcdedit.exe) looks fine. I'm confused - surely if its not been able to map the blockdevice as a filesystem device it should not boot? I would like to be able to get the boot to proceed without my interaction - does anyone know how to do it? (Also there is no Boot Manager options available in the shell, i.e. autoboot, bcfg etc)

  • Is there a way to launch a command within a proper zsh shell ?

    - by Wam
    I'm not really clear with my question here, let me rephrase it : I've setup a launch_workspace.sh to launch directly tmux with 5 different commands loaded. Here is my current content : #!/bin/sh tmux new-session -d -s scube -n 'vim' "vim" tmux new-window -t scube:2 -n 'server' "$SHELL -c 'script/rails server'" tmux new-window -t scube:3 -n 'yard' "$SHELL -c 'bundle exec yard server --gems'" tmux new-window -t scube:4 -n 'spork' "$SHELL -c 'bundle exec guard'" tmux new-window -t scube:5 -n 'autotest' "$SHELL -c 'bundle exec autotest'" tmux new-window -t scube:5 -n 'shell' "$SHELL" tmux select-window -t scube:1 tmux -2 attach-session -t scube Problem is : my zsh ($SHELL beeing zsh) launches said commands, but when I Ctrl+C any of these, it closes the full zsh (hence my tmux window) and not just return to a proper zsh prompt. Is there a way to have said behavior, to launch zsh with a command and return to a zsh prompt when the command fails ? Cheers

  • Open a terminal window & run command, then close the terminal window if command completed successfully?

    - by Caspar
    I'm trying to write a script to do the following: Open a terminal window which runs a long running command (Ideally) move the terminal window to the top left corner of the screen using xdotool Close the terminal window only if the long running command exited with a zero return code To put it in Windows terms, I'd like to have the Linux equivalent of start cmd /c long_running_cmd if long_running_cmd succeeds, and do the equivalent of start cmd /k long_running_cmd if it fails. What I have so far is a script which starts xterm with a given command, and then moves the window as desired: #!/bin/bash # open a new terminal window in the background with the long running command xterm -e ~/bin/launcher.sh ./long_running_cmd & # move the terminal window (requires window process to be in background) sleep 1 xdotool search --name launcher.sh windowmove 0 0 And ~/bin/launcher.sh is intended to run whatever is passed as a command line argument to it: #!/bin/bash # execute command line arguments $@ But, I haven't been able to get the xterm window to close after long_running_cmd is done. I think something like xterm -e ~/bin/launcher.sh "./long_running_cmd && kill $PPID" & might be what I'm after, so that xterm is launched in the background and it runs ./long_running_cmd && kill $PPID. So the shell in the xterm window then runs the long running command and if it completes successfully, the parent process of the shell (i.e. the process owning the xterm window) is killed, thereby closing the xterm window. But, that doesn't work: nothing happens, so I suspect my quoting or escaping is incorrect, and I haven't been able to fix it. An alternate approach would be to get the PID of long_running_cmd, use wait to wait for it to finish, then kill the xterm window using kill $! (since $! refers to last task started in the background, which will be the xterm window). But I can't figure out a nice way to get the PID & exit value of long_running_cmd out of the shell running in the xterm window and into the shell which launched the xterm window (short of writing them to a file somewhere, which seems like it should be unnecessary?). What am I doing wrong, or is there an easier way to accomplish this?

Can't find anything in the manual to suggest why.

  • source command in Linux

    - by Rodnower
    My question is: why if I run some file with name aliases for example with content such as: alias lsa="ls -a" directly: $ ./aliases it don't create the alias (may be only in script context). But if I run it with command "source": $ source aliases it do the work? I mean after execution the alias "lsa" existing in context of command shell? "man source" give: "No manual entry for source", and in google I just found that it runs Tcl, but why Tcl influence shell context and bush not?

  • shell script over SSH ends unexpectedly after running 'ant build'

    - by YShin
    I wrote a shell script that runs on remote host to build source code with 'ant build' command, and then distribute the built binary to other servers. However, right after Ant build is over successfully(I can see the command line output saying Build was successful), the ssh session ends and whatever commands after 'ant build' does not get executed. I'm confused what might be cause of this behavior. I suspected that it might be because the 'ant build' command takes too long time, and SSH somehow quits itself after that long command. But I don't think that's correct since if I just do 'sleep 60' in place of 'ant build' command, it actually execute latter commands as intended. I'm new at shell programming, so I might have made some silly misassumption. Can someone provide a pointer to a possible cause of this problem? My shell script #!/bin/bash # Inject some variables ssh -T $SSH_USER@$SSH_URL "setenv REMOTE_BASE_DIR $REMOTE_BASE_DIR; setenv CASSANDRA_SRC_TAR_FILE $CASSANDRA_SRC_TAR_FILE; setenv CASSANDRA_SRC_DIR_NAME $CASSANDRA_SRC_DIR_NAME; setenv CLUSTER_SIZE $CLUSTER_SIZE; setenv REMOTE_REDEPLOY_SCRIPT $REMOTE_REDEPLOY_SCRIPT; /bin/bash" << 'EOF' export JAVA_HOME=/usr/lib/jvm/jdk1.7.0 cd $REMOTE_BASE_DIR/$CASSANDRA_SRC_DIR_NAME echo "## Building Cassandra source" ant clean build # Anything after this doesn't run echo "## Ant Build is over.
