How can I change the keyboard shortcut for switching tabs in Mac Terminal?
I know that you can switch tabs with shift cmd [arrow key] in Mac Terminal, but it is painful to reach the arrow key. How can I change the default keybinding?
Reset colors on Windows command line (cmd)
I often run commands in cmd.exe that have pretty colors in their output, which is great. Unfortunately, sometimes they die in the middle, or I have to kill them, and then the console window itself gets stuck in (say) red text on black background, which is awkward. How do I reset the text color to the default? On a unix terminal, I can type -- I'm looking for the cmd.exe equivalent of that.
Create an SSH user who only has permission to access specific folders
I installed SSH, but I found if I use my original account to login to Ubuntu, it has too many permissions. I want to constrain the user to only have permissions for specific folders in Ubuntu. How can I configure such a user?
Excel Conditional Formatting Escaping a Question Mark
I would like to use a conditional formatting rule in an excel file that would color any box with a question mark in it red. It seems that Excel is using a question mark as a wild card and will turn all cells with at least one character in them red. How can i escape the question mark? These don't seem to work: "?" \? '?' ??
Is there a way to batch rename files to lowercase?
I need a way to rename all files in folders and subfolders to lowercase. I'd like to know if there is a way to do that using only windows (XP or 7)
Does vertical position affect the lifespan or integrity of a hard drive?
I've noticed on many small PC cases that the hard drives are installed vertically. In midi cases, towers and others of a larger housing, they are in the horizontal position. What impact on a hard drive does a vertical position have? Does it affect the life? Is it more prone to errors? (Not of SSDs (solid-state drive), just plain hard drive with all its mechanical parts inside.)
How can I pass an environment variable through an ssh command?
How can I pass a value into an ssh command, such that the environment that is started on the host machine starts with a certain environment variable set to my choosing? EDIT: The goal is to pass the current kde desktop ( from dcop kwin KWinInterface currentDesktop ) to the new shell created so that I can pass back an nfs locations to my JEdit instance on the original server which is unique for each KDE desktop. ( Using a mechanism like emacsserver/emacsclient) The reason multiples ssh instances can be in flight at one time is because when I'm setting up my environment, I'm opening a bunch of different ssh instances to different machines.
Any way to "ungroup" taskbar items in Windows?
I mostly like the improvements in Windows 7, but am pretty annoyed with the new Taskbar... particularly its habit of always keeping items grouped. Is there any way to ungroup the taskbar items in Windows? And just for the record, "Never combine" does not work. True, setting this option creates a separate button for each instance of an application... but it still groups all the running instances together. For instance, all Explorer Windows are grouped together beside each other, and they can only be dragged around as a group---not as individual items.
What technical reasons exist for not using space characters in file names?
Somebody I know expressed irritation today regarding those of us who tend not to use spaces in our filenames, e.g. -- despite most modern operating systems supporting spaces in filenames. Are there technical reasons that it's still common to see file names without (appropriate) spaces? If so, what are these technical reasons that spaces in filenames are avoided or discouraged, and in what circumstances are they relevant? The most obvious reason I could think of, and why I typically avoid it, are the extra quotes required on the command line when dealing with such files. Are there any other significant technical reasons?
What's the difference between one-dash and two-dashes for command prompt parameters?
I was wondering why is it that some programs requires their command prompt parameters to have two dashes in front whereas some (most) only require one dash in front? For example most programs look like this: Whereas some programs look like this: What's the reason that some requires two dashes instead of one? Doesn't it make sense for everyone to stick to one standard (i.e. a single dash will do).
Getting the bundle identifier of an OS X application in a shell script
One option would be to use AppleScript: You could also do something like this: Both of these are fairly slow (about 0.05-0.2s on my Air) though. Are there any faster or less hacky options?
How to make ssh-agent automatically add the key on demand?
I want to run ssh-agent (with maximum lifetime option), but not add any keys at startup, but instead add them on demand. Like first time I login to some server it should ask for passphrase, next time (unless I waited for more than a hour) it should connect cleanly: I don't want to manually remember about running 'ssh-add' each time. (e.g. entered passphrase for just for ssh and "Oh, it hasn't remembered, need to retype"). How to configure ssh to automatically add key to ssh-agent if user provided the passphrase?
"net start service" and "sc start". What is the difference?
Services can be stopped and started using two commands in Command Prompt Shell. net start service "some service" sc start "some service" what is the difference between these commands?
How do I associate my keyboard's media keys with VLC media player?
I've got an ASUS K50AF series notebook with Windows 7 Home Premium x64. I'm using VLC media player, and I want to use media keys (play, pause, rewind, forward, stop) with it. Currently, they're associated with Windows Media Center. I've tried MK2MP. Unfortunately, it didn't fix my problem, and crashed after restarting VLC media player. Run time error 31 at line 559 Now, I can't even start MK2MP. Any ideas? I've disabled Media Center and Media Player. HIP now recognizes media keys, but the keys still don't do anything. It seems that when I try capturing that key, all programs (including HIP, Key Mapper and AutoHotkey) thinks I pressed the H key.
How to stop a currently running cron job?
How can I stop a cron job which is currently running?
How to update Cygwin from Cygwin's command line?
To search and download a package missed from Cygwin I need to run setup.exe GUI each time, click many times and do other boring things. Is there a way to do the same from Cygwin's command line directly? Like apt-get tools do.
How to list printer names acceptable for use with lpr?
The man page says a destination printer can be specified with the flag. I have 'added' various printers on local Samba shares using the GUI in Ubuntu/Gnome. How can I get a list of these available printers in the format that the flag expects (preferably from a bash shell)?
How to export an individual bookmark folder in Google Chrome?
In my bookmarks window I have two to three folders like , and . How do I export the folder only from Google Chrome?
Windows 7, file properties, date modified, how do you show seconds?
Anyone know a way to immediately show the seconds of a file's date modified property in the GUI? So if you create a file, any file in any directory, right-click and choose Properties, the date modified (if it's recent) will say something like "dd/mm/yyy hh:mm, one minute ago" - reminder this is in Windows 7. Windows XP did it normally. Then they changed something. If you wait a while, eventually you'll see the seconds, I'm not sure how long a while is, but this is incredibly annoying if you want to troubleshoot something that relies on the seconds of timestamps... is there a setting? registry key I can change perhaps? I'm literally using Chrome, pasting in the path of the directory to be able to see the seconds quickly (as a workaround) but would be nice to be able to use Win7.
Export PowerPoint to PDF with each animation on a separate slide
I have a PowerPoint presentation where I extensively use simple animations, only appear/disappear effects triggered by the mouse (not time based), without any smooth transitions. Is it possible to export a PDF where every single step of the animation is on a separate slide?. The problem is that, exporting through the save-as menu, each slide in the pdf is just a snapshot of the corresponding powerpoint slide (with everything visible). Example: Suppose I have the following slide that start visualizing the shape : clicking the mouse or pressing the right arrow triggers the 'appear' event for the shape : clicking the mouse or pressing the right arrow triggers the 'disappear' event for the shape : The PDF exported file of this PowerPoint animation will have a single slide with , while I would like to have three separate slides.
