• Linux wall command won't broadcast strings

  - by mjb

  I read here that this should work, but it doesn't: //usage: wall [file] root@sys:~> mesg is y root@sys:~> wall "who's out there" wall: can't read who's out there. If mesg is set to y, what's preventing me from broadcasting a string? Note, I did confirm that the file option works: root@sys:~> wall test Broadcast Message from root@sys (/dev/pts/1) at 15:23 ... Who's out there? Teach me knowledge please. mjb

• delete duplicate files with windows batch file?

  - by Chris Sobolewski

  I have a program that automatically copies files to a directory, and if it creates a duplicate it will name it like so: file with duplicate.xxx file with duplicate - 1.xxx file with duplicate - 2.xxx I need a way to delete all the duplicates with a windows batch file. Something along the lines of: FOR %f IN (C:\files\*.*) DO del "%f - 1" However, that will not work because that would resolve to file with duplicate - 1.xxx - 1

• avoiding console window display when scheduled task runs batch file

  - by cherouvim

  I have a small batch file which xcopies some files from one folder to another which I've scheduled (via windows scheduled tasks) to run every 1 hour: @echo off xcopy c:\foo c:\bar /E /C /F /Y Since this is my workstation, I'm most probably doing work when the task executes, and then the black dos console window is displayed (lasts 2-3 seconds) and steals window focus. I don't wish to see the files copied and of course the batch file does not ask for any user input. Is there a way to avoid displaying the console completely?

• Is it possible to make Ctrl+C as responsive as Ctrl+Break in the Windows 7 console?

  - by Peter Graham

  Is it possible to make Ctrl+C act like Ctrl+Break in the Windows 7 cmd.exe console? By default Ctrl+C seems to only send a signal the next time the input buffer is read, where Ctrl+Break sends a signal immediately. This makes Ctrl+C useless for ending processes because when I want to end a process I want to end it immediately. I'm using Ctrl+Break for now but it's far harder to type. It looks like in DOS you can add BREAK=ON to CONFIG.SYS to achieve this, but not in Windows 7?

• zsh conditional statement help

  - by Roy Rico

  Feeling kinda dumb right now: Why is my contional always true? I've tried # this should let me know what's not a directory or # symbolic link. whoa=`find ${MUSICDIR} ! -type l ! -type d | wc -l` # I would expect if it's 0 (meaning nothing was found) that # one of these statements would evaluate to false, but so far # it's always evaluating to true if [[ "${whoa}" != "0" ]] if [[ ${whoa} -gt 0 ]] What am I missing?

• Induce Mac graphical login from SSH

  - by Ben Alpert

  The title says it all. Is there a way to make the loginwindow process start a user session by running a command when remotely logged in via SSH as an admin on Mac OS X? When the machine is at the login window (no user is currently logged in), I want it to open up a user's session as if I had clicked on the username and entered a password. Solutions that don't involve scripting the GUI are highly preferred, but this Apple KB page may be of interest for those who go that route.

• Does a successful exit of rsync -acvvv s d guarantee identical directory trees?

  - by user259774

  I have two volumes, one xfs, and another ntfs - ntfs was empty, and xfs had 10 subitems. I needed to sync them. I initially copied a few of the subitems by dragging them over in a gui fm. Several of the direct descendants which i had dragged finished, apparently. One I stopped before it was done, and the rest I cancelled while it still appeared to be gathering information about the files. Then I ran rsync -acvvv xmp/ nmp/, where xmp and nmp are the volumes' respective mountpoints, which exited with a 0 status. find xmp -printf x | wc -c and find nmp -printf x | wc -c both return 372926. My question is: Am I guaranteed that the two drives' contents are identical?

• How to solve this problem with a 'tuned' prompt in ZSH?

  - by Mnementh

  I have an adjusted prompt in my ZSH-configuration. Main feature is, that this prompt is colored red, so that I can easily it distinguish from the outputs of programs. My prompt is defined as follows: PROMPT=$'\e[0;31m%n@%m:%~> \e[0m' This works mostly fine, but sometimes my cursor switches to another position on tab-completion and some characters are left behind on the screen and mangle up the commandline. That is a little annoyance, but if someone knows a solution for this, I would appreciate it.

• Opening Python in CMD (Unfixable Error)

  - by Robert

  I recently tried opening one of my Python projects with CMD to see what would happen. The result did nothing amazing, but Windows 7 thought I wanted to open .py files in CMD all the time. I have tried everything, setting it back to python.exe does not work, I even went to Control Panel to see if it could help, but Control Panel couldn't help either. So if someone could help me please that would be great. Thank you.

• Windows CMD, show the current folder name at prompt dynamically like Bash

  - by guneysus

  I am trying to modify my CMD, to show only current dir name dynamically like: Desktop $ When i switched the folder, it must be updated.

• Use DOS batch to move all files up 1 directory

  - by Harminoff

  I have created a batch file to be executed through the right-click menu in Win7. When I right-click on a folder, I would like the batch file to move all files (excluding folders) up 1 directory. I have this so far: PUSHHD %1 MOVE "%1\*.*" ..\ This seems to work as long as the folder I'm moving files from doesn't have any spaces. When the folder does have spaces, I get an error message: "The syntax of the command is incorrect." So my batch works on a folder titled PULLTEST but not on a folder titled PULL TEST. Again, I don't need it to move folders, just files. And I would like it to work in any directory on any drive. There will be no specific directories that I will be working in. It will be random. Below is the registry file I made if needed for reference. Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\shell\PullFiles] @="PullFilesUP" [HKEY_CLASSES_ROOT\Directory\shell\PullFiles\command] @="\"C:\\Program Files\\MyBatchs\\PullFiles.bat\" \"%1\""

• Configure bash_profile for one single terminal emulator

  - by Hugo

  I'm using a new terminal emulator. Terminology is the E17 default terminal, and it have a great command, $ tyls with is a "graphical" $ ls I want to create an alias just for this terminal, because the command "tyls" don't make sense to konsole, rxvt or other terminals. I'm thinking in some kind of "if" in ~/.bash_profile to test if I'm on terminology and then run the following command: alias ls="tyls" But how can I test if I'm in terminology but not xterm? Can someone help me? Thanks!

• Advanced merge directory tree with cp in Linux

  - by mtt

  I need to: Copy all of a tree's folders (with all files, including hidden) under /sourcefolder/* preserving user privileges to /destfolder/ If there is a conflict with a file (a file with the same name exists in destfolder), then rename file in destfolder with a standard rule, like add "old" prefix to filename (readme.txt will become oldreadme.txt) copy the conflicted file from source to destination Conflicts between folders should be transparent - if same directory exists in both sourcefolder and destfolder, then preserve it and recursively copy its content according to the above rules. I need also a .txt report that describes all files/folders added to destfolder and files that were renamed. How can I accomplish this?

• Configure GNU screen so that it stores command histories in files

  - by user65950

  I would like to configure GNU screen such that it stores the command histories of all the different windows in different files. I know by default GNU screen does not store the command histories (of its different windows) in a file at all (it stores them in memory instead), but it might be possible to tell it to store them in files instead? The different command history files should have the names <session>.<window>.history, or similar. Does anyone have an idea how to do that? (Just to be clear, I want each GNU screen window to write a different file. I like that each window has a different history, and I typically run different types of commands in the different windows.)

• How do I change colors on-the-fly in mintty?

  - by Thomas L Holaday

  How do I change the colors in a Cygwin mintty session which is already open? Is it possible? Use case: Under environment-imposed time constraints, multiple terminal windows have been opened without forethought. In order to reduce the risk of typing the commands for system A into the terminal for system B, it would be nice if they were different colors. Is there some escape sequence or whatnot that can change the color scheme for a running session?

• Is there a way to hide Mac Terminal credentials?

  I lose too many columns in my terminal because of the credentials ( Victor-Rodriguess-MacBook-Pro:~ victorrodrigues$ ). Could I shrink this? The only information I see as really needed sometimes for me is the folder name, nothing else.

• Run WMIC command across network

  - by C-dizzle

  Instead of typing this in a command prompt one at a time: wmic /node:ipaddress /user:administrator /password:mypassword bios get serialnumber How can I run that against one entire subnet and output to a text document? Since I do this every couple months to verify our inventory of computers, I would assume there would be a much of easier way I could put this in a batch script instead of doing it manually.

• powershell run java process problem

  - by Limited Atonement

  Dear Sirs, I'm trying to run a java process via Powershell in Windows XP. Here's the command: java.exe -cp .;./common.jar -Dcontext=atest1 -Dresourcepath=. DW_Install So, the classpath is . and .\common.jar (I think java takes the wrong slashes, right?) There are two environment variables, one "atest1" the other "." and the class to execute main on is DW_Install (in the default package). This command works in cmd.exe, but doesn't is PS. What's going on? What is PS doing while parsing this command that CMD doesn't do (or vice versa)? Aaron

• How do I extract files from one tarball to another tarball in one step?

  - by Martin

  I have some fairly large tarball archives, from which I need to extract some files. I will later repack those files to transfer them to another server. Currently that is a two (multi) step process for me: mkdir ttmp tar -vxzf large.tgz -C ttmp/ --strip-components=<INT> <folder-to-be-extracted> or alternatively with wildcards mkdir ttmp tar -vxzf large.tgz -C ttmp/ --strip-components=<INT> \ --wildcards --no-anchored '*pattern*' Then I go ahead and recompress the created folder tar -vczf small.tgz ttmp/* rm -rf ttmp How can I combine these two commands into one? Like this tar -x large.tgz > tar -c small.tgz Just to show, what I already tried: Whenever I search the terms "extract" I will end up here or here or even here. When I use the term "split" I will end up here and that is definitely not what I intend to do. When I use "repack" I end up in strange places.

• Renaming dates under windows cmd

  - by ldigas

  I have a bunch of directories (folders, if you like) that follow this pattern \20121022 Description of the directory's contents goes here\ (some don't have it, just the date) and I need to rename them to follow the following pattern \2012-10-22 Description of the directory's contents ...\ Is there a way to do it using Windows cmd and the tools that come with it (namely, ren)? If not, what would be the most portable way to do it? I have a very restricted set of privileges on the machine I'm doing this on.
