  • Exclude specific filename from shell globbing

    - by Alsciende
    Hi, I want to excluse a specific filename (say, fubar.log) from a shell (bash) globbing string, *.log. Nothing of what I tried seems to work, because globbing doesn't use the standard RE set. Test case : the directory contains fubar.log fubaz.log barbaz.log text.txt and only fubaz.log barbaz.log must be expanded by the glob.

  • C Language Standard Collections Where Are They?

    - by flaxeater
    I have committed to learning C now, I'm good with Python/PHP/Bash but I've decided I'm limited by not being fluent in C. However I cannot imagine working in a language without lists and hashes, maybe I'm just jumping a gun, but surely there are 'standard' collection libraries. I do not see any in the GNU standard lib though, any suggestions?

  • How can I save shell output to a variable in LaTeX?

    - by Frank
    I need to be able to execute a shell command through LaTeX [*] and have the resulting output available for use later on in the form of a LaTeX 'variable' (e.g., via a subsequent \newcommand command). If necessary a temporary file could be used to hold the output, although I would like to avoid this. I have been able to use \immediate\write18 to invoke a bash command before, but this was only used to write to a temporary file. [*] I realise that the -shell-escape flag must be set for this to be allowed

  • Where is my software installed in Linux?

    - by David
    I use whereis matlab and find: /usr/local/bin/matlab , which is a very long bash file. How can I find where matlab is installed, I mean, its installed folder. EDIT: I used the following method: open matlab and use edit svds.m to open the svds.m file and the editor shows the folder:)

  • Print numbers sequentially using printf with filling zeroes

    - by Werner
    Hi, in C++, using printf I want to print a sequence of number, so I get, from a "for" loop; 1 2 ... 9 10 11 and I create files from those numbers. But when I list them using "ls" I get 10 11 1 2 .. so instead of trying to solve the problem using bash, I wonder how could I print; 0001 0002 ... 0009 0010 0011 and so on Thanks

  • vim autopopulate file

    - by David Oneill
    Is it possible to have VIM auto populate a file based on the extension? For example, when I open a new .sh file, I would like VIM to automatically type #!/bin/bash as the first line. (This example simplified down to the essentials)

  • how to search for a term only in non test files

    - by dorelal
    I use ack and I like it. However from time to time I need to search for something in my code base and I want to ignore all the files residing in test directory. Basically all the files which have test in their absolute path should be not included in the search. How do I achieve that? I am willing to have a custom bash script. Something like ack_no_test "application" - search for "application" in all files but ignore files residing in test directory

  • detect when a webpage is updated

    - by Martin Trigaux
    Hello, There is a website (very simple) which will be updated soon and I'd like to receive an alert at the moment it changes (like a sound, a popup,...) I guess I should send request every x minutes and compare the result with what's now but I don't know how to do that. I don't really care about the language used, I know java, python, php, a bit of c and bash (I'm on linux)... Thank you

  • Asterisk - Trying to use call files to create a conference call between two dynamic numbers

    - by Hank
    I'm trying to setup an Asterisk system that will allow me to create a conference call between two dynamic numbers. It seems I can use 'call files' to make Asterisk initiate the call without needing an incoming call - http://www.voip-info.org/tiki-index.php?page=Asterisk+auto-dial+out This example seems to be what I'd need: Channel: SIP/mytrunk/12345678 MaxRetries: 2 RetryTime: 60 WaitTime: 30 Context: callme Extension: 800 Priority: 2 I can generate this file with some scripting language and then place it into the Asterisk Call File folder. The problem I'm having is: How do I call out to two numbers and join them in a conference call? The MeetMe plugin/extension seems to be what I need in terms of conference calling, I'm just unsure as to how I'd use the two together and join them. Also, is it possible to have multiple 2-person conference calls at the same time? Is setting this up as simple as setting aside X amount of 'channels' in the meetme.conf?

  • Unable to run openoffice in headless mode

    - by uswaretech
    I want to automoate some PPT - PDF conversions, so I want to run openoffice in headless mode for scripting. On my machine with X running I can start opemoffice in headless mode via soffice -accept="socket,port=8100;urp;" -headless This doesn't seem to work on a server with X not running. $ soffice -accept="socket,port=8100;urp;" -headless /usr/lib/openoffice/program/soffice.bin X11 error: Can't open display: Set DISPLAY environment variable, use -display option or check permissions of your X-Server (See "man X" resp. "man xhost" for details) $ The error doesnt seem to make sense as well, as the point of specifying -headless was so that I do not need X, while this command seems to look for X.

  • What proportion of DBA skills are platform-independent?

    - by Arkaaito
    Problem: we've grown to the point where we need a real DBA. Real DBAs are hard to find. Possible solution: I know someone with extensive experience (currently working on MSSQL) who is looking for a new DBA job. He might be willing to consider working for a MySQL shop (I haven't asked). Snag: I don't know to what extent MSSQL DBA skills map to MySQL DBA skills. I'm a developer, so I know enough about MySQL to develop apps which use it (including the basic performance-tuning, index selection, etc.), do schema design, and perform simple utility tasks (backup with mysqldump, scripting, etc.). I don't know anything about MSSQL. Nor do I actually know much about the boundaries of the DBA role. Can anyone with more experience - perhaps as a DBA - weigh in on this? Are there enough similarities between MSSQL and MySQL that it's worth asking a MSSQL DBA if he'd be interested in applying for a MySQL position?

  • Is Cygwin the best unix environment for Windows?

    - by nik
    Which unix like environment do you prefer on Windows? I have found Cygwin to be very comfortable for a windows platform (usually XP). I am wondering if there is a better alternative (not because I want to move away from Cygwin). What are the features of Cygwin that you like OR, What are features you find in alternatives that you miss in Cygwin? I am often miss binary compatibility of applications built on Cygwin. These cannot be run directly on another Windows platform. But, usually fetching a copy of cygwin1.dll suffices. A collection of other tools many of which work directly on the Windows subsystem rather than emulating unix, like Cygwin does. Have been referred PowerShell a lot of times for scripting on Windows Earlier, UnixUtils was suggested more often Microsoft Windows Services for Unix

  • Detecting source of memory usage on a Linux box

    I have a toy Linux box with 256mb RAM running Ubuntu 10.04.1 LTS. Here is the output of free -m: total used free shared buffers cached Mem: 245 122 122 0 19 64 -/+ buffers/cache: 38 206 Swap: 511 0 511 Unless I'm reading this wrong, 122mb is being used and only 84mb of that is disk cache.

What's more, memory usage is growing all the time. I've had to restart my server once a week, because once my 256mb fills up it starts swapping, which it wouldn't do just for disk cache. Shouldn't there be some way for me to see the culprit?! I'm new to server admin, so please if there's something obvious I'm overlooking point it out to me. Just for good measure, the output of cat /proc/meminfo: MemTotal: 251140 kB MemFree: 124604 kB Buffers: 20536 kB Cached: 66136 kB SwapCached: 0 kB Active: 65004 kB Inactive: 37576 kB Active(anon): 15932 kB Inactive(anon): 164 kB Active(file): 49072 kB Inactive(file): 37412 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 524284 kB SwapFree: 524284 kB Dirty: 8 kB Writeback: 0 kB AnonPages: 15916 kB Mapped: 10668 kB Shmem: 188 kB Slab: 18604 kB SReclaimable: 10088 kB SUnreclaim: 8516 kB KernelStack: 536 kB PageTables: 1444 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 649852 kB Committed_AS: 64224 kB VmallocTotal: 34359738367 kB VmallocUsed: 752 kB VmallocChunk: 34359737600 kB DirectMap4k: 262144 kB DirectMap2M: 0 kB EDIT: I had misinterpreted the meaning of free -m at first. But even so: the important thing is that my OS eventually begins to use swap memory if I don't restart my server, which disk caching wouldn't do. So where do I look to see what is using all this memory?

  • Conditionally create symbolic link by filesize using find exec ubuntu 10.04

    - by jmlw
    I have an interesting problem. I'm trying to create symbolic links in a single folder, for all files in a directory which are larger than a specified size. For clarification, here is an example: /Files /Large_Files /LargeFile1_symlink /LargeFile2_symlink /Folder1 /file_a /file_b /Folder2 /LargeFile1 /Folder3 /LargeFile2 /file_c What I have so far to try to accomplish this is: find -size +102400 -exec ln -s $PWD/{} Large_Files/ \; However, this find produces ./LargeFile1 So my symlink command produces ln -s /Files/Folder2/./LargeFile1 Large_Files/ My question is, would it be possible to use the basename command to separate out only the filename so this command will work? Or does anybody have a suggestion on how to do this without writing a script, or give me an example on writing a script? I've never done scripting before, but I do know Java, but don't want to take the time to do all this in Java. Thank you for any help! Edit: adding tags
