  • Interactive console based CSV editor

    - by Penguin Nurse
    Although spreadsheet applications for editing CSV files on the console used to be one of the earliest killer applications for personal computers, only few of them and even less documentation about them is still actively maintained. After having done extensive search on the web, manpages and source code, I ended up with the following three applications that all have fundamental drawbacks: sc: abbrev. for spreadsheet calculator; nice tool with vi keybings, but it does not put strings containing the delimiter into quotas when exporting to delimiter separated format and can't import csv files correctly, i.e. all numbers are interpreted as strings GNU oleo: doesn't seem to be actively maintained any longer since 2001 and there are therefore no packages for major linux distributions teapot: offers packages for various operating systems, but uses for example counter-intuitive naming for cells (numbers for row and column, i.e. 11 seems to be intended to be row 1, column 1) and superfluous code for FLTK GUI Various Emacs modes also do not quote strings containing the delimiter well or are require much more typing for entering the scaffold of a table. Therefore I would be very grateful for overcoming one of theses drawbacks or any hints towards another console based CSV editor. It actually needn't do any calculations just editing cells or column- and rowise.

  • XCOPY /Exclude Directory Syntax

    - by Onion-Knight
    I'm trying to use XCOPY to copy a directory that looks like this: -MainFolder -ManyFoldersIWantToCopy -ManyFoldersIWantToCopy -... -Source Code I want to use the /EXCLUDE option to copy every folder except Source Code. I tried using the following, but I did not have any luck: xcopy "Source" "Destination" /EXCLUDE:"\Source Code\" /E /C /R /I /K /Y The error message I receive says: Can't read file: "\Source Code\". I've tried removing the double-quotes all together, using single-quotes instead, with/without the \'s, but I get the same error message. Any ideas?

    I'm quite new to strace / netstat / etc. I'm using this command to get a trace of the apache process handling my request (telnet), is there a way to simplify it a bit? sudo strace -o /tmp/strace -f -s4096 -r -p $(netstat -antlp | \ grep $(lsof -p `pidof telnet` | grep TCP | \ perl -n -e'/localhost:(\d+)/ && print $1') | grep apache2 | \ perl -n -e'/ESTABLISHED (\d+)/ && print $1') Thanks!

  • icacls in windows 7 does not give full permission to write files in root drive

    - by Menuta
    icacls in windows 7 does not give full permission to write files in root drive. We have a very old application based on Omnis7 that needs to create and read/write files on drive C: when running as a restricted user. In Windows XP to give this permission is quite trivial using cacls. cacls C:\ /G Everyone:(C) The equivalent icacls in Windows 7 will not work. icacls C:\ /Grant Everyone:(M) I have also tried the following. icacls C:\ /Grant Everyone:(F) icacls C:\ /Grant Domain\user:(F) trying to create file with a restricted user gives this C:\>copy nul text.txt Access is denied. 0 file(s) copied. After applying the icacls permissions above the result changes to this. C:\>copy nul text.txt A required privilege is not held by the client. 0 file(s) copied. Is this an issue with the way I am applying the permissions? Or is Window 7 being extremely strict?

  • Why does cat not use options the way I expect UNIX programs to use switches?

    - by Chas. Owens
    I have been a UNIX user for more years than I care to think about, and in that time I have been trained to expect that when contradictory switches are given to a program the last one wins. Recently I have noticed that cat -bn file and cat -nb file both use the -b option (number blank lines) over the -n option (number all lines). I get this behavior on both BSD and Linux, so I don't think it is an implementation quirk. Is this something that is specified somewhere and am I just crazy for expecting the first example to number all lines?

  • Setting cmd with default command and user defined message

    - by gpuguy
    On button click in a winform application I am executing cmd.exe file (Using system("cmd.exe");), which opens perfectly fine and displays the following: Microsoft Windows XP [Version 6.1.7601] (C) Copyright 1985-2001 Microsoft Corp.

  • Add folder name to beginning of filename

    - by shekhar
    I have a directory structure as below: Folder > SubFolder1 > FileName1.abc > Filename2.abc > ............. > SubFolder2 > FileName11.abc > Filename12.abc > .............. > .......... etc. I want to rename the files inside the subfolders as: SubFolder1_Filename1.abc SubFolder1_Filename2.abc SubFolder2_Filename11.abc SubFolder2_Filename12.abc i.e. add the folder name at the beginning of the file name with the delimiter "_". The directory structure should remain unchanged. Note: Beginning of file name is same. e.g. in above case File*. I made below Script for /r "PATH" %%G in (.) do ( pushd %%G for %%* in (.) do set MyDir=%%~n* FOR %%v IN (File*.*) DO REN %%v "%MyDir%_%%v" popd ) Problem with the above script is that it is taking only one Subfolder name and placing it to the beginning of file name irrespective of the folder.

  • how to word wrap, align text like the output of man?

    - by cody
    what is the command that word wraps and justifies a text file so that the output looks like that of a man page: All of these system calls are used to wait for state changes in a child of the calling process, and obtain information about the child whose state has changed. A state change is considered to be: the child terminated; the child was stopped by a signal; or the child was resumed by a signal. In the case of a terminated child, performing a wait allows the system to release the resources associated with the child; if a wait is not performed, then the termi- nated child remains in a "zombie" state (see NOTES below). Thanks.

  • GNU Screen and Finch Not Playing Nicely

    - by Sean M
    I use finch for instant messaging, and for persistence, finch is one of the things that runs in my screen session. There are three main computers that I access my screen session from, and each works at a different screen resolution. Because of the different resolutions, when I switch computers, I use screen -rd to attach to my screen session. Using screen -x results in problems. When I attach to the session, though, finch experiences display problems. I have to wait up to several minutes for finch to become responsive - it doesn't redraw properly at all. Trying to switch between chats just writes ^n and ^p, or ^(1-9) for numbers. It fixes itself after some time. Using ctrl-l does not help. Switching back and forth between screen windows does not help. This is an annoying behavior that I don't experience with any other applications running in screen. Is this a bug in screen or finch, and if not, what can I change about my configuration to correct it ? (would appreciate it if "finch" could be used as a tag for this instead of or in addition to "pidgin")

  • How can I install OpenSolaris without Graphical Environment - just text console?

    - by Sanoj
    I would like to install OpenSolaris and use it as a home-server. I will interact with it just with SSH, so I don't need the Graphical Environment. How can I install OpenSolaris without the Graphical Environment? And preferably I would like to use the SSH-interface as much as possible, is it even possible to do the installation over SSH? I tried the SSH-boot alternative on the installation-CD, then I have to use a password, but I have no password since I haven't installed the system yet.

  • Cron won't use msmtpd to send emails in case of failed cronjob

    - by Glister
    I'm trying to configure a machine so that it will send me an email if one of the cronjobs output something in case of an error. I'm using Debian Wheezy. Cron is working normally (without the email functionality). msmtp is installed and configured. Have already symlinked /usr/{bin|sbin}/sendmail to /usr/bin/msmtpd. I can send email by using: echo "test" | mail -s "subject" [email protected] or by executing: echo "test" | /usr/sbin/sendmail Without the symlink (/usr/sbin/sendmail) cron will tell me that: (CRON) info (No MTA installed, discarding output) With the symlinks I get: (root) MAIL (mailed 1 byte of output; but got status 0x004e, #012) Can you suggest how to config the cron/msmtp pair? Thanks!

  • Alternative Windows shell?

    - by user17943
    I can't stand the Windows "shell". 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 (please, do not answer "Linux".)

  • Directory and Sub Directory listing

    - by shekhar
    I am trying to list the directory name (only name, not full path) and sub directories (only name, not full path) inside it. There is only one level of sub directories. I used below script to do this: @echo off&setlocal enableextensions for /r "PATH" %%G in (.) do ( Pushd %%G for %%* in (.) do set MyDir=%%~n* echo %MyDir% popd ) endlocal&goto :eof The problem with the above script is that it is showing root directory with the full path. How can I just make it show the directories in relation to the one I am working in?

  • Can't escape single quotes in shell

    - by user13743
    I'm trying to make a command to do a perl substitution on a batch of php files in a directory. The string I want to replace has single quotes in it, and I can't get it to properly escape the in shell. I tried echoing the string with unescaped quotes, to see what perl would be getting: echo 's/require_once('include.constants.php');/require_once('include.constants.php');require_once("./functions/include.session.inc.php");/g' and it doesn't have the single-quotes in the result: s/require_once\(include.constants.php\);/require_once\(include.constants.php\);require_once\("\./functions/include\.session\.inc\.php"\);/g However, when I try to escape the single quotes: echo 's/require_once\(\'include\.constants\.php\'\);/require_once\(\'include\.constants\.php\'\);require_once\("\./functions/include\.session\.inc\.php"\);/g' I get the prompt to complete the command: > What I want it to parse to is this: What am I doing wrong? s/require_once\('include.constants.php'\);/require_once\('include.constants.php'\);require_once\("\./functions/include\.session\.inc\.php"\);/g

  • Differential backup missing moved folders (flawed archive attribute logic)

    - by Max
    Recently I've discovered that my backup system it flawed: there are situation where various files/folders are missed. I do my backup from local disk to a network NAS. I use Cobian backup, and I have setup the backup software to create one full backup every week, and one differential backup every day. Now, the backup software (to my knowledge any backup software work this way) decide the files that go in the differential backup by looking at the file archive attribute. If the attribute is set, then the file go in to the backup. Now, when you move a file to a new location, on Windows systems, the archive attribute get set and the file is included in the backup, and that's fine... but when you move an entire folder, no archive attribute is set, nor on the folder, nor in any files inside the folder, so the moved folder isn't included in the differential backup! So, if you have a full backup plus a differential backup, and you moved folders around... then it's impossible to reconstruct the original files/folders structure starting from the full+differential backup, because the backup software didn't include the moved folders in the differential backup. So my differential backup are useless... Why does windows set the archive attribute when moving a file, but not when moving a folder? How can I deal with this issue? Is there a way to create a differential backup that works as it's supposed to do? Doing full backup every day is not practical, because the changed data is about 0.1% at day (by using a differential backup I can keep 4 weeks of files history without using too much disk space.)

    I am using a mac (snow leopard). I am a ruby on rails developer and I watched a screencast on GNU screen and am trying it out. So far I like it. On a window when I start server I get to see the log messages. However I can't seem to scroll up. I do get a scroll bar. However when I use the scroll bar and scroll up I don't see anything. How do people use GNU screen and scroll up?
