  • Xcopy /exclude does not exclude some of the specified criteria

    - by Richard Z.
    Good afternoon. I want xcopy to copy all files meeting a certain criteria located in the C drive to a specific folder, except ones located in the directories specified in excl.txt. The exclusions only work partially - the files located in %systemroot%, %programfiles% and in each profile's appdata are still copied, even though those directories are listed in excl.txt. How do I make xcopy skip those directories, preferentially still using environment vars to specify the paths? My current syntax is: xcopy /s /c /d /h /i /r /y /g /f /EXCLUDE:excl.txt %systemdrive%\*.doc f:\test\ excl.txt currently contains the following: \%temp%\ \%userprofile%\appdata \%programfiles%\ \%programfiles(x86)%\ \%systemroot%\ \%programdata%\ appdata windows %programfiles% Thank you very much.

  • Virtual terminal with at least 16bit color?

    - by trusktr
    It's 2013 and there should be terminals with more than 256 colors by now (you'd think). Are there any terminals with more than 8bit colors (usually from 8 bit we jump to 16bit) to use with linux? Ideally, I'd like to have a linux terminal with 32bit colors for the foreground and background of each character. So, the functionality would be the same, with escape sequences, but just more of them (or something like that?).

  • Download a file via HTTP from a script in Windows

    - by Jason R. Coombs
    I want a way to download a file via HTTP given its URL (similar to how wget works). I've seen the answers to this question, but I have two changes to the requirements: I'd like it to run on Windows 7 or later (though if it works on Windows XP, that's a bonus). I need to be able to do this on a stock machine with nothing but the script, which should be text that could be easily entered on a keyboard or copy/pasted. The shorter, the better. So, essentially, I'd like a .cmd (batch) script, VBScript, or Powershell script that can accomplish the download. It could use COM or invoke IE, but it needs to run without any input, and should behave well when invoked without a display (such as through a telnet session).

  • script calling script as other user

    - by viktor tron
    Using CentOs, I want to run a script as user 'training' as a system service. I use daemontools to monitor the process, which needs a launcher script that is run as root: : #!/bin/bash exec >> /var/log/training_service.log 2>&1 setuidgid training training_command This last line is not good enough since for training_command, we need environment for training user to be set. : su - training -c 'training_command' gives 'standard in must be tty' as su making sure tty is present to potentially accept password. I know I could make this disappear by modifying /etc/sudoers a la Bash & 'su' script giving an error "standard in must be a tty" but i am reluctant and unsure of consequences. : runuser - training -c 'training_command' gives runuser: cannot set groups: Connection refused. I found no sense or resolution to this message. I am stuck. Is this something so hard to achieve? I appreciate all insight and guidance to best practice.

  • Reconfiguring, then deleting obsolete pagefile.sys from C: in one go using a batch script

    - by DanielSmedegaardBuus
    I'm trying to set up an automated script for a Windows XP installer. It's a batch script that runs on first boot after installation, and among the things I'm trying to accomplish, is removing the pagefile from C: entirely, and putting a 16-768 MB pagefile on D: instead. Here're my batch file instructions: echo === Creating new page file on D: ... cscript %windir%\system32\pagefileconfig.vbs /create /i 16 /m 768 /vo d: >nul echo. echo === Removing old page file from C: ... cscript %windir%\system32\pagefileconfig.vbs /delete /vo C: attrib -s -h c:\pagefile.sys del c:\pagefile.sys My problem is that while these are sane commands, the removal of the pagefile on C: requires me to reboot before those commands succeed.b Or, in other words — I have to first create the D: pagefile, then reboot and delete the c:\pagefile.sys file, or I'm stuck with a c:\pagefile.sys file which isn't even recognized by Windows itself (it'll just say that there's a page file on D:, and that C: has no pagefile at all). Obviously because already some pages are written to the C:\pagefile.sys file. So how would I go about accomplishing this in one go? Or, in two gos, if this is "batch scriptable" :) TIA, Daniel :) EDIT: I should probably clarify: Running those commands above are all valid, but they'll only succeed fully if I re-run the "attrib" and "del" commands at next boot. The C: pagefile is in use at the time, so I cannot delete the file it uses, and Windows itself won't remove it when I configure it to not use C: as a page file drive. Instead, it'll leave an orphaned c:\pagefile.sys file behind (which is really large). I don't necessarily need this to work in one go, registering the last two commands to run after a reboot would also be great :)

  • Schedule Windows XP wallpaper change without additional apps

    - by Thomas
    Ideally, I'd like to be able to do this through a batch file or VB script, so I can schedule it to run at different times of the day (dark wallpaper at night vs. light wallpaper at day). I am aware of the many applications which could do this, but I prefer to keep only necessary applications running in the background.

  • using sed to replace 1 line with a multi-line variable in ksh

    - by Manda
    I have the following text in a file: XXXX NNNN YYYY NNNN ZZZZ NNNN I want to replace the NNNN to make it look like this: XXXX NNNN DUTY FORECASTER: YYYY NNNN DUTY FORECASTER: ZZZZ NNNN DUTY FORECASTER: How do I use sed to replace a variable with more than one line? Is there a better way of doing this without using sed? I have tried the following to no avail: sed 's/NNNN/"$value1"/g' testfile sed 's/NNNN/'"$value1"'/g' testfile sed 's/NNNN/${value1}/g' testfile sed 's/NNNN/'"${value1}"'/g' testfile I have also tried all of the above using double quotes. Any help is greatly appreciated. Thanks so much!

  • how do i set index priorty on nginx in order to load index.html before wordpress' .php files

    - by orbitalshocK
    hello there, gents. I'm an absolute beginner in linux, the CLI, as well as nginx and wordpress. i'm trying to make a 'coming soon' landing page that will take priority over the main wordpress installation i just set up. I want to make .html load before php, or get information on the Best Practices approach to this. I just now realized i could easily use the wordpress' generic "under construction" page and modify it. I'm sure it has one; i'm sure there's a plugin. Stats linode 1024 ubuntu 12.04 nginx 1.6.1 single wordpress installation (for now) set up using easyengine, but going to restart and configure nginx for my linode specifically probably. I managed to find one piece of instruction on how to change the httpd file to specify priority for apache 2, but did not find the same documentation for nginx. If it's not on the first page of google, then serverfault needs the question answered! Viva la Server Fault first page results!

  • Setup mutt to read through a threaded message and then return to the email index

    - by dat5h
    I have begun using mutt (terminal email client) recently and I have it setup very nicely and easy to use. My only gripe is that sometimes it is difficult to tell when I transition from one thread to the next. Is it possible to setup the bindings such that moving to the next-undeleted message would check if the next-undeleted message is in the same thread, and if that check is false it returns to the index or throws an error? For example, I currently have bind pager <down> next-undeleted bind pager } next-subthread Is there a more advanced function call that could perform this check? I haven't been able to find much on how to perform more complex function calls with such checks while checking out the manual. Any help would be appreciated.

  • How can I suppress /etc/issue without losing error messages?

    - by Andy
    Is it possible to tell the ssh client to not print the connects of /etc/issue to stdout when connecting to a remote host, but to print out any other diagnostic (e.g. error) messages? Either using ssh -q or having LogLevel quiet in ~/.ssh/config suppresses the /etc/issue printing, but also turn off error messages. I've tried touching ~/.hushlogin as well - that stops /etc/motd being printed, but doesn't affect /etc/issue. The most obvious solution is just to remove /etc/issue, but company policy dictates the file be there with dire warnings about unauthorised access. This is non-negotiable. Unfortunately, I've got a bunch of scripts that run across quite a few hosts via ssh, and the log files are a) very large and b) full of legalese. Since quite a lot of stuff runs unattended, I don't want to lose any error messages that are printed.

  • Run script when a specific disk/memory card is mounted under OSX

    - by Max Rydahl Andersen
    How do I run a script when a drive is mounted under OSX ? My usecase is that I would like to automatically copy images from my USB memory/harddrive when it is inserted in my USB card reader, and when a DVD or CD is inserted I would like to copy it for storage in my media center. I've tried using Marcopolo but from what I can see it can only detect the presence of a certain USB device, not the presence of specific harddrive. (http://superuser.com/questions/65127/is-it-possible-to-run-an-automator-workflow-when-a-usb-device-is-connected)

  • Linux how to force an external ping from eth0 to eth1 without a router.

    - by Elie
    Hello, i am trying to have eth0 connected to eth1 on the same machine with a loopback cable. I have eth0 as 2.2.2.1 and eth1 as 2.2.2.2 with netmask 255.255.255.0 and the right Bcast 2.2.2.255 . I tried to ping -I eth0 2.2.2.2 and ping -I eth1 2.2.2.1. My issue is that even when the loopback cable is not plugged the ping still succeed( as if it is an internal ping). How can I force an external ping where I make sure the packets are going through the connected cable? ( I know I can have a router and both ethernets connected to it, but I am avoiding to use anything besides a simple cat 5 cable). Thanks.

  • How do I export HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe with regedit from cmd.exe?

    - by René Nyffenegger
    I am trying to export the registry key HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe but am unable to do so, probably because of the percent signs. I tried to escape the %-sign with a caret or another %-sign, but this didn't help me: regedit /e c:\temp\cmd.reg "HKEY_CURRENT_USER\Console\%%SystemRoot%%_system32_cmd.exe" and regedit /e c:\temp\cmd.reg "HKEY_CURRENT_USER\Console\^%SystemRoot^%_system32_cmd.exe" So, is there a way to do what I want. Edit as per ??????? ???????????'s comment: the key is the exact string, with the percent signs. So I don't want %SystemRoot% expanded, but passed to regedit as is.

  • Robocopy Mirror Backup gone awry

    - by Aznfin
    I have created a simple batch file script for running Robocopy. It is set to make a backup of my user account folder to my external hard drive. Here's the parameters for Robocopy: ROBOCOPY "C:\Users\Finnly" "F:\Backups\Finnly (Backup)" /ZB /COPY:DAT /DCOPY:T /MIR /256 /MT:32 /XF *.log *.log* *.dat *.tmp *.temp *.old "ntuser*" "SyncToy*" "UpgKit.txt" ".recently-used.xbel" /XD ".gimp-2.6" ".thumbnails" ".VirtualBox" "AppData" "Application Data" "Adobe" "Camtasia Studio" "Cookies" "CyberLink" "DivX Movies" "DVD Architect Pro 5.0 Projects" "dwhelper" "GTA San Andreas User Files" "Lightroom" "Local Settings" "NetHood" "PrintHood" "Scripts" "temp" "Templates" "The KMPlayer" "Tracing" /R:3 /W:10 /V /TS /FP /ETA /LOG+:F:\Backups\Sync.log /TEE For some reason when I run it, it backs up the files and then it seems to back them up again. The size of my user account directory is 18.3 GB but the backup of it occupies over 30 GB. After reading the contents of the log generated, it is obvious that it's copying files more than once. Why is this happening? I'm running Windows Seven Home Premium 64-bit.

  • Windows 7 File Associations .mov

    - by Paul Mung
    I created a new windows 7 SP1 base image. Everything is all fine and dandy with that. So i am now installing standard applications I would like Quicktime to manage .mov files. The only problem is WMP (Windows Media Player) won't give up the association to .mov files. It's driving me crazy... i've been reading threads on how to fix file associations. I would like to do it via registry, powershell or cmdline. I cannot use GPO I've tried the following: assoc .mov=QuickTime.mov ftype QuickTime.mov="%ProgramFiles(x86)\QuickTime\QuickTimePlayer.exe" Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\UserChoice" /v Progid /d QuickTime.mov /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v a /d QuickTimePlayer.exe /f Reg add "HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v b /d wmplayer.exe /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v MRUList /d ab /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithProgids" /v Quicktime.mov /t REG_NONE /d 0000 /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithProgids" /v WMP11.AssocFile.MOV /t REG_NONE /d 0000 /f

  • reduce timeout when connecting to wrong IP (XP-XP, windows explorer)

    - by Viki
    I have many shortcuts in the form \10.0.0.123\path in Windows Explorer (XP). Some of the IPs are sometimes dead (those vmware machines that are inactive). The problem is, when I try to open "Properties" on such shortcut (to correct the IP, or to delete it), Windows Explorer freezes for minutes. For very long time. Start menu freezes, too. This is very inconvenient. How can I reduce the windows explorer timeout when it is probing the connection to another XP share ?

  • How to simply remove everything from a directory on Linux

    - by Tometzky
    How to simply remove everything from a current or specified directory on Linux? Several approaches: rm -fr * rm -fr dirname/* Does not work — it will leave hidden files — the one's that start with a dot, and files starting with a dash in current dir, and will not work with too many files rm -fr -- * rm -fr -- dirname/* Does not work — it will leave hidden files and will not work with too many files rm -fr -- * .* rm -fr -- dirname/* dirname/.* Don't try this — it will also remove a parent directory, because ".." also starts with a "." rm -fr * .??* rm -fr dirname/* dirname/.??* Does not work — it will leave files like ".a", ".b" etc., and will not work with too many files find -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr find dirname -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr As far as I know correct but not simple. find -delete find dirname -delete AFAIK correct for current directory, but used with specified directory will delete that directory also. find -mindepth 1 -delete find dirname -mindeph 1 -delete AFAIK correct, but is it the simplest way?

  • pam_exec.so PAM module does not export variable PAM_USER as stated in the documentation

    - by davidparks21
    I'm trying to use the pam_exec.so PAM module to execute a script which needs to know the username/password coming from the application (OpenVPN in this case). I have a script that executes printenv >>afile, but I don't see all the environment variables that the man pages states that pam_exec.so exports (namely PAM_USER I think), I only see the following: PAM_SERVICE=openvpn PAM_TYPE=auth PWD=/usr/local/openvpn/bin SHLVL=1 A__z="*SHLVL I do successfully pick up the password off of STDIN and output it with this same script. But for the life of me I can't get the username. Any thoughts on what I should try next?
