  • cut text from each line in a txt file

    - by bboyreason
    i have a text file where each line looks like this: <img border=0 width=555 height=555 src=http://websitelinkimagelinkhere> each line is like that for like 1500 lines, i want to sort of 'grep' (i dont think that will work because it returns the whole line) each line for 'http://websiteimagelinkhere' output file should have newlines or tabs after each image link, like the original file. or if someone only knows a way to do this with each element being in a cell of the same column that would be okay too.

  • Passing multiple sets of arguments to a command

    - by Alec
    instances contains several whitespace separated strings, as does snapshots. I want to run the command below, with each instance-snapshot pair. ec2-attach-volume --instance $instances --device /dev/sdf $snapshots For example, if instances contains A B C, and snapshots contains 1 2 3, I want the command to be called like so: ec2-attach-volume -C cert.pem -K pk.pem --instance A --device /dev/sdf 1 ec2-attach-volume -C cert.pem -K pk.pem --instance B --device /dev/sdf 2 ec2-attach-volume -C cert.pem -K pk.pem --instance C --device /dev/sdf 3 I can do either one or the other with xargs -n 1, but how do I do both?

  • How do I change the .bash_history file location?

    - by Brian Graham
    I'm running CentOS 6.x and want to move the .bash_history to a different location. The home directories of my users are (because I run a VPS) in /var/www/vhost/<domain>.<tld> which is FTP accessible (and it should be). Because of this, I have changed the AuthorizedKeysFile for SSH connections out of the normal ~/.ssh/authorized_keys since FTP connections would easily be able to locate them. At the same time I want to move the .bash_history file to /home/%u/.bash_history where %u is the current user.

  • Running a command line app with sudo and password automatically on OS X startup

    - by Designer023
    I need to run an app at startup/login on my mac. I want it to launch in the background and start doing it's work without interrupting me or me having to start it up because I invariably forget and then when I need it, it wasn't running! I have tried using AppleScript to tell Terminal to run it and type my password in, but it ends up opening multiple Terminal windows and not working. Ideally I need a script that I can just add to the user login items and it will run for me. The app has no way of taking a password argument either and it has a password as well as the sudo! I need a solution that can either be done as an applescript (which can be made into an executable) or i need a commandline script but I have no idea about them. This is the manual code I type $ sudo serverStatus password:123456 password:serverpass My AppleScript: tell application Terminal activate do shell script "sudo serverStatus" delay 5 do shell script "123456" delay 2 do shell script "serverpass" end tell

  • How do I read multiple lines from STDIN into a variable?

    - by The Wicked Flea
    I've been googling this question to no avail. I'm automating a build process here at work, and all I'm trying to do is get version numbers and a tiny description of the build which may be multi-line. The system this runs on is OSX 10.6.8. I've seen everything from using CAT to processing each line as necessary. I can't figure out what I should use and why. Attempts read -d '' versionNotes Results in garbled input if the user has to use the backspace key. Also there's no good way to terminate the input as ^D doesn't terminate and ^C just exits the process. read -d 'END' versionNotes Works... but still garbles the input if the backspace key is needed. while read versionNotes do echo " $versionNotes" >> "source/application.yml" done Doesn't properly end the input (because I'm too late to look up matching against an empty string).

  • Avoiding users to corrupt and use a script

    - by EverythingRightPlace
    Is it possible to deny the right to copy files? I have a script which should be executable by others. They are also allowed to read the file (though it would not be a problem to forbid reading). But I don't want the script to be changed and executed. It's not a problem to set those permissions, but one could easily copy, change and run the script. Can this even be avoided? /edit The OS is Red Hat Enterprise Linux Workstation release 6.2 (Santiago).

  • Is there a unix command to output time elapsed during a command?

    - by Olivier Lacan
    I love using time to find out how long a command took to execute but when dealing with commands that execute sub-commands internally (and provide output that allows you to tell when each of those sub-commands start running) it would be really great to be able to tell after what number of seconds (or milliseconds) a specific sub-command started running. When I say sub-command, really the only way to distinguish these from the outside is anything printed to standard out. Really this seems like it should be an option to time.

  • Using watch with pipes

    - by Tom
    Hi! I'd like to run this command: watch -n 1 tail -n 200 log/site_dev.log | grep Doctrine But it does not run, because "I think" that the grep tries to run on the watch instead of the tail... Is there a way to do something like watch -n 1 (tail -n 200 log/site_dev.log | grep Doctrine) Thanks a lot!

  • Can't access Terminal anymore, only shows a cursor

    - by user138304
    I run OS X. Following these directions (Installing MySQL on Mac OS X) I added a file to /usr and the contents were PATH=/usr/local/mysql/bin:$PATH Actually I was trying to get the mysql command to work now I cannot access terminal. All I get is a cursor but no command line. I also cannot find the file I created in the Finder. I used command shift G to find the folder /usr and the file is not there. Edit: I Solved the problem by restarting my computer. I am really not sure what the problem was. I got the idea because Could not open a new pseudo-tty. appeared in my terminal after following slhck directions to remove my .profile file. I then searched google and found this; http://blogs.oreilly.com/digitalmedia/2008/03/fixing-terminal-tty-errors.html. Thanks

  • `adduser [options] user group` fails ubuntu 11.04

    - by Rob
    I'm want to use adduser However it doesn't seem to work if I provide the second argument for the user's group root@a:~# adduser rick staff adduser: The user `rick' does not exist. The group exists root@a:~# addgroup staff addgroup: The group `staff' already exists. The man page says this should work... adduser [options] user group Any ideas? I can do: adduser --ingroup staff rick So no massive issue, just seems strange.

  • Automake thumbnail

    - by Webmaster
    What I need to do is a program that given (as a command line argument) a directory with more directoreies inside, and 4 Pics inside of each dir, the program makes a thumbnail of the 4 files and glues them together (2 rows, 2 columns) and renames that image to the name of the directory. I think it could be done with a combination of a program and shell scripting (I'm experienced in M$, but new to linux). Some real examples would be great. Thanx in advance

  • How to cd into smb://[email protected] from terminal?

    - by John
    I am using ubuntu and gnome on my computer. When I open up File Browser, on the left hand rail, I see conveniently a folder called "Work Server". When I mouse over it, the following caption appears "smb://[email protected]". If I click on that folder, then I can see the contents of that folder. Everything is great. So now when I open up a terminal/shell, I type in cd smb://[email protected] I get an error saying the directory doesn't exist. How do I enter this directory via shell/terminal?

  • Problems when loop over a series of ssh-ed commands

    - by Jack Medley
    I have a series of server machines which I want to run the same command on. Each command takes hours and (even though I am running the commands using nohup and setting them to run in the background) I have to wait for each to finish before the next starts. Here is roughly how I have set it up: On the host machines: for i in {1..9}; do ssh RemoteMachine${i} ./RunJobs.sh; done Where RunJobs.sh on each remote machine is: source ~/.bash_profile cd AriadneMatching for file in FileDirectory/Input_*; do nohup ./Executable ${file} & done exit Does anyone know of a way such that I dont have to wait for each job to finish before the next starts? Or alternatively a better way of doing this, I have a feeling what I am do is fairly sub-optimal. Cheers, Jack

  • Passing the output of the last command to sed as an argument

    - by neurolysis
    Hi, Basically, I'm wanting to automate adding something to xorg.conf in the right place, I've used some commands to get the line number of the line I want to manipulate, but I'm not really sure how to go about passing this line number (as an argument and NOT something to be manipulated) to sed. I have been told about xargs and looked at the docs on it, but after some reading and experimentation I can't seem to get it to work. In case anyone can think of a better method entirely, the process I want to automate is just finding the line containing both "Identifier" and "Monitor0" (there will only be one) and adding a line below it. The problem with just finding Monitor0 and manipulating that line is that there are multiple lines with Monitor0 in. I've got this far: fgrep -n "Monitor0" </etc/X11/xorg.conf | fgrep "Identifier" | cut -f1 -d: This gives out the line number which I'm wanting to pass to sed, but I'm not really sure how to do it. ...or is there a simpler way which I'm not seeing? Thanks. :)

  • unexpected behaviour of Ctrl-a x and Ctrl-a X in screen?! regions, locking

    - by gojira
    According to the screen manual (version 4.0.2.) C-a x C-a C-x (lockscreen) Lock this terminal. C-a X (remove) Kill the current region. But what actually happens when I use it (Screen version 4.00.03 (FAU) 23-Oct-06): C-a X locks the terminal and asks me for the password. When I enter the correct passwword, I am back in screen but the region is killed (wtf) C-a x does nothing apparently Please note the differences between x (lowercase) and X (uppercase). Why is there a mixup between the functionalities of C-a X and C-a x? How can I fix this? I am on CentOS release 5 (Final).
