  • Windows preventing running of Telnet client

    - by palswim
    At first, I had issues because Windows 7 doesn't install the Telnet client by default (also, SuperUser has a thread). So, after installing it (and restarting, like Windows asked, though completely unnecessary), I opened a command prompt, and went to run my new Telnet program. I enter telnet, and receive: C:\Users\[USER]>telnet 'telnet' is not recognized as an internal or external command, operable program or batch file. "That's odd," I think to myself. So, in Windows explorer, I navigate to \Windows\System32 and see telnet.exe sitting in that folder. If I double-click on the executable file, the Telnet command prompt opens for me without a problem. So, I return to my Windows Command Prompt, and enter: C:\Users\[USER]>\Windows\System32\telnet.exe '\Windows\System32\telnet.exe' is not recognized as an internal or external command, operable program or batch file. And then (grep comes from cygwin): C:\Users\ryan\Desktop>dir \Windows\System32 | grep telnet Nothing. I've disabled UAC and have no idea why my Command Prompt is lying to me. Anyone experience something similar? To recap: In Windows 7, I have installed Telnet and can see it in my System32 folder, but cannot run it via a Command Prompt.

  • How to filter running in VLC video stream on commandline?

    - by Rais
    I easily can broadcast my webcam with VLC using command lines like this (I use Windows): "C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" -vvv -I --dshow-vdev="Logitech QuickCam Express / Go" dshow:// --sout When I paste command into CMD and hit enter it starts streaming (all is fine - I can play it). How can I now for example add brightness or any other filter to that stream from the commandline?

  • Count requests from access log for the last 7 days

    - by RoboForm

I would like just a number, no categories and only for the last 7 days. Thanks.

  • save as pdf in linux

    - by Neilvert Noval
    I have seen how simple it is for Mac OS to generate pdf from a document without additional software to install. But I am looking for this functionality in Linux. One scenario, for example, if I have myDocument.txt that contain an article, how can I convert this into pdf? My next question is, assuming that myDocument.txt is a 3-paged document, will it generate a 3-page continuous pdf and not just 3 separate pdfs? Any tools for linux that does this? (GUI is fine, but commandline is preferable)

  • Is there a way to catch cmd.exe windows into tabs?

    - by user55542
    I use an editor that allows me to type in a command to run. In order to see the output without having to redirect it to a file, I precede the command with "cmd /k," which leaves an open cmd.exe window. So I'd like to find a way to move catch the call to cmd.exe and give it to an application that tabifies cmd.exe, a terminal emulator as it's called. The desired result would be similar to what happens in a tabbed editor, when that editor is to open some file, it does so in another tab, and not in another window. While in a given situation it may be easier to modify the command to redirect output to display in the editor itself, in general it would be more helpful if I could find a way to catch all such calls into one window.

  • How to change my commandline locale after CentOS decided to change it?

    - by Aron Rotteveel
    So apparently, CentOS decided I was Dutch, and thus, should not have a English locale. Apart from the fact that this greatly bothers me, I am having a pretty hard time actually changing it back. There does not seem to be a setlocale function, and system-config-language tells me I am using an English locale, even though my environment says otherwise. Any help would be appreciated. Output from locale: LANG=nl_NL.UTF-8 LC_CTYPE="nl_NL.UTF-8" LC_NUMERIC="nl_NL.UTF-8" LC_TIME="nl_NL.UTF-8" LC_COLLATE="nl_NL.UTF-8" LC_MONETARY="nl_NL.UTF-8" LC_MESSAGES="nl_NL.UTF-8" LC_PAPER="nl_NL.UTF-8" LC_NAME="nl_NL.UTF-8" LC_ADDRESS="nl_NL.UTF-8" LC_TELEPHONE="nl_NL.UTF-8" LC_MEASUREMENT="nl_NL.UTF-8" LC_IDENTIFICATION="nl_NL.UTF-8" LC_ALL= Both my ~/.bashrc as ~/.bash_profile contain no locale settings. Additionally, /etc/bashrc does not contain any locale references either.

  • CMD: How do I delete all the contents of all directories (in the current directory) without deleting the directories themselves?

    - by merlin2011
    For example: I'm in the directory: F:\Data Inside this directory, I have four directories: F:\Datadir 22179 22915 23459 23460 These directories have various content, including directories and files. I'm trying to run something like: rmdir /s *\* where I delete all the contents of these numbered directories, while leaving the empty directories. Is there a one-liner that can do this, or do I have to loop through the sub-directories?

  • Audio organizing via CLI

    - by Radek Šimko
    I'm looking for some software for my OpenSUSE, which with I would be able to organize my audio files. I've found one, which may be good, but it's unable to run without X server (in CLI). http://musicbrainz.org/doc/MusicBrainz_Picard I'm not looking for ID3 renamers. There're maybe hundreds of them... I'm looking for software, which has its own database, or is able to communicate with some database, like CDDB, Gracenote, last.fm etc.

  • In Bash, how can I obtain the directory path from the previous command's last argument

    - by Beaming Mel-Bin
    I frequently have to do this. For example: $ vim /etc/pam.d/sudo $ vim /etc/pam.d/sudo-i $ cd /etc/pam.d/ # Figure I should just go to the directory Now, is there a way I could obtain the directory of the last argument when it's a file path? I'm asking this cause I recently became aware of the $_ variable that has become useful. Was wondering if there's some other commandline fu that might come in handy.

  • Alternative Windows command shell and console?

    - by user17943
    I can't stand the Windows command "shell" and console window. I can't copy text off a command prompt window, the .bat syntax is retarded, I can't stand how the command buffer works, it doesn't support ANSI color codes, I could go on and on. Are there any alternatives to the Windows command prompt?

  • how to check if something is in the queue of torque?

    - by kloop
    I want to re-run some jobs that completed prematurely under torque. These jobs are run through .job scripts (using qsub). However, I don't want to re-run a job which is already in the queue. Given a script filename, how can I know whether it is already in torque's queue (using qstat?) or not? I prefer to do it programmatically, of course, so any oneliner that searches for a given script name would be great. I will note that I can grep submit_args in qstat -f, but I can't get it to display the whole script name when it is too long. This is crucial. EDIT: I managed to solve it using the following command: qstat -x | perl -pi -e 's/\<\//\n/g' | grep job$ | grep -v submit_args | perl -pi -e 's/Job_Id\>\<Job_Name\>//' works because all my scripts end in the string "job".

  • Enter response once prompt returns?

    - by mjb
    It's neither a secure idea nor one I'd recommend elsewhere, but I have a situation when occasionally it takes a while for my Ansible ad-hoc command to respond. I'd love to pipe or args or whatever is needed to push the required text into the prompt so I can walk away and know it will finish. Ex: $ ansible all -m shell -a "reboot" --ask-pass Password: blah blah blah it worked I'd love to send an argument or << or something to get the password in. Is that possible?

  • Files copying between servers by creation time

    - by driftux
    My bash scripting knowledge is very weak that's why I'm asking help here. What is the most effective bash script according to performance to find and copy files from one LINUX server to another using specifications described below. I need to get a bash script which finds only new files created in server A in directories with name "Z" between interval from 0 to 10 minutes ago. Then transfer them to server B. I think it can be done by formatting a query and executing it for each founded new file "scp /X/Y.../Z/file root@hostname:/X/Y.../Z/" If script finds no such remote path on server B it will continue copying second file which directory exists. File should be copied with permissions, group, owner and creation time. X/Y... are various directories path. I want setup a cron job to execute this script every 10 minutes. So the performance is very important in this case. Thank you.

  • SSH to drive letter in Windows 2003

    - by JohnnyG76
    I have a Windows 2003 server running a SSH server (WRQ Reflection), how would I ssh to it and specify a specific drive letter? (like the D: drive) ex: from another workstation: ssh [email protected] d: When I do that it fails and I get this error: "exec request failed on channel 0" If I simply SSH to that same windowsbox without trying to specify a drive letter I get a Windows (CMD.EXE) command prompt shell on the C: drive. I can then run any windows command. Thanks

  • Use of hyphen in shell command

    - by deanloh
    I feel shy to ask this question, but if I don't I will never know, so here I am giving it a shot: I notice most shell commands use "-" for options, but I also noticed some commands do not have it. For example, to archive files in a given direct, the command is: tar czvf allmyfiles.tar.gz * However, to extract an archive, the command I learned, is: tar -zxvf allmyfiles.tar.gz Looking at both examples above, is there any significance whether to include the hyphen or not?

  • Runas command for user without password

    - by user156558
    I want to use the runas command in CMD and from Batch files to gain elevated permissions, but I don't have an admin password on my PC because it's my home computer and I'm the only user. Every time I try to use the runas command it asks me for a password, then tells me that blank passwords are not permitted, is there any way round this? I know I can just right click and select run as administrator, but I would much rather have a command that can do it as that is not always an option, and it's just a bit of a pain. I could just be making some kind of basic mistake as I'm not hugely experienced with command prompt, but I'm not completely clueless.
