• Why is the Task Manager Total Physical Memory not 2048 MB or 2 GB

  - by Dorothy

  I found 3 numbers for the Total Physical Memory: In the Task Manager under the Performance tab: 1978 MB In Computer Properties: 2 GB And running wmic computersystem get TotalPhysicalMemory /format:list in the command line: 2074554368 Bites Number 1 matches Number 3 except Number 1 is rounded. When I convert Number 3 to GB 2074554368 / 1024 / 1024 / 1024 I don't quite get 2 GB. I get 1.93207932 GB. Why does Number 1 and Number 3 not match Number 2?

• Slow tab completion for paths in`make' arguments

  - by ajwood

  When I'm specifying an argument for make like PREFIX_PATH=/some/path/to/prefix/ I sometimes experience very slow completion for my directories (a few seconds). It's annoying when I've got several variables to specify. To get around the problem I've been typing out the variables first to get regular completion speed, then hitting home' to insertmake` that the start of my command line. What is happening and how can I fix it?

• Utility for extracting MIME attachments

  - by tripleee

  I am looking for a command-line tool for Unix (ideally, available in a Debian / Ubuntu package) for extracting all MIME parts from a multipart email message (or the body from a singlepart with an interesting content-type, for that matter). I have been using the mimeexplode tool which ships with the Perl MIME::Tools package, but it's not really production quality (the script is included as an example only, and has issues with what it regards as "evil" character sets) and I could certainly roll my own script based on that, but if this particular wheel has already been innovated, perhaps I shouldn't.

• Hidden features of Ubuntu

  - by Tom Brito

  That I know: In command line, use TAB to autocomplete the commands. You need just to select a text to copy it, and use mouse middle button to paste. Which other "untold" secrets Ubuntu hides? obs. I don't know which of the items I told are for any Linux or Ubuntu specific.

• Mass Checksumming tool for Windows?

  - by Daniel Magliola

  Hi, I'm looking for a command line tool for windows that will go over a directory tree (recursively) and output a list of all the files in there, and a checksum for each file (can be CRC, MD5, whatever). Esentially, what I want is to compare 2 big directory trees in 2 machines. I'm planning to take the outputs of running this tool in both, and diffing them to make sure they're identical. I appreciate any ideas.

• Need to remove borders from multiple images

  I have a few hundred family images and they were all sent to us with borders that I would like to remove. Thankfully the borders are all the same size of 20 pixels and they are all .jpg so this will probably make things easier but im looking for a way to "batch process" all of them quickly so I dont need to open photoshop for each image and do it individually. Command line is preferred, the only big problem is they are mostly different sizes. Here is an example

• Executing a command in vim from a commandline

  - by TK

  I would like to run :helptags ~/.vim/doc in vim, but from command line. The purpose is to run the command occasionally with other commands to keep my tools up-to-date (probably in a cron job on my development machine. I looked around man vim, but cannot figure out what option I need to pass. I think this is a general question for vim, but I'm using Mac and Ubuntu for the development.

• How can I tell if Windows is running in Safe Mode?

  - by cwd

  I have a Windows server that will sometimes reboot into safe mode after updates. I'm working on that issue but what I'd really like to know is how can I check to see if Windows is running in safe mode or not. Ideally I would like to incorporate it into a script that would send a passive check to our Nagios box with the status. Is there some environmental variable I can use or some way to get this information via the command line?

• Monitor number of bytes transferred to/from IP address on port.

  - by Mike

  Can anyone recommend a linux command line tool to monitor the number of bytes transferred between the local server and a specified IP address/port. The equivalent tcpdump command would be: tcpdump -s 0 -i any -w mycapture.trc port 80 host google.com which outputs : 46 packets captured 131 packets received by filter 0 packets dropped by kernel I'd like something similar that outputs: 54 bytes out, 176 bytes in I'd like it to work on RHEL and be free/open-source. It would be good if there was an existing tool which I was just missing too!

• How to change the default terminal emulator on Windows (cmd)?

  - by alex

  Is it possible to change the default terminal emulator on Windows (7 and 8 in particular) from cmd to, for example, Console2 or ConEmu? In essence, I want all command line tools, whether launched by double clicking, from "Run" or by other processes to use the custom terminal. This is a trivial matter on Linux, is it even possible on Windows? It would be especially helpful if this could be done via a script.

• recursively delete empty directories in windows

  - by mohlsen

  I have a directory on my Windows 7 machine that has hundreds if not thousands of sub-directories. Some of them have files, some do not. I want to delete all the empty directories. Looking at the del and rmdir DOS command, it does not look like you can recursively do this without deleting all the files. Is there a way to do this from the command line? Or is there a tool that would do it for me?

  Is there some command within Thunderbird or command line to will allow me to pipe a list of all email addresses I've received emails from to a file? I would like to do this for a specific email account and folder within Thunderbird as well, and not just all of my accounts. I have maybe 100 unique people who have sent me an email for some contest and it would be optimal not to have to type all of this stuff up by hand. Thanks!!!

• What is the Windows analog of the Linux watch command?

  - by PeterJCLaw

  I'm looking for a Windows program/script/command line function that works like Linux's watch program. watch periodically calls another program/whatever and shows the result, which is great for refreshing an output file or similar every second: watch cat my-output.txt or, more powerfully: watch grep "fail" my-output.txt I've looked for it in cygwin's library, but it doesn't seem to be present.
