  • Inserting text in a file from a variable

    - by user754905
    I have a file that looks something like this: ABC DEF GHI I have a shell variable that looks something like this: var="MRD" What I want to do, is to make my file look like this: ABC MRD DEF GHI I was trying to do this: sed -i -e 's/ABC/&$var/g' text.txt but it only inserts $var instead of the value. I also tried this: sed -i -e 's/ABC/&"$var"/g' text.txt but that didn't work either. Any thoughts? Thanks!

  • Using find and tar with files with special characters in the name

    - by Costi
    I want to archive all .ctl files in a folder, recursively. tar -cf ctlfiles.tar `find /home/db -name "*.ctl" -print` The error message : tar: Removing leading `/' from member names tar: /home/db/dunn/j: Cannot stat: No such file or directory tar: 74.ctl: Cannot stat: No such file or directory I have these files: /home/db/dunn/j 74.ctl and j 75. Notice the extra space. What if the files have other special characters? How do I archive these files recursively?

  • Catching / blocking SIGINT during system call

    - by danben
    I've written a web crawler that I'd like to be able to stop via the keyboard. I don't want the program to die when I interrupt it; it needs to flush its data to disk first. I also don't want to catch KeyboardInterruptedException, because the persistent data could be in an inconsistent state. My current solution is to define a signal handler that catches SIGINT and sets a flag; each iteration of the main loop checks this flag before processing the next url. However, I've found that if the system happens to be executing socket.recv() when I send the interrupt, I get this: ^C Interrupted; stopping... // indicates my interrupt handler ran Traceback (most recent call last): File "crawler_test.py", line 154, in <module> main() ... File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/socket.py", line 397, in readline data = recv(1) socket.error: [Errno 4] Interrupted system call and the process exits completely. Why does this happen? Is there a way I can prevent the interrupt from affecting the system call?

  • Why is my producer-consumer blocking?

    - by User007
    My code is here: http://pastebin.com/Fi3h0E0P Here is the output 0 Should we take order today (y or n): y Enter order number: 100 More customers (y or n): n Stop serving customers right now. Passing orders to cooker: There are total of 1 order(s) 1 Roger, waiter. I am processing order #100 The goal is waiter must take orders and then give them to the cook. The waiter has to wait cook finishes all pizza, deliver the pizza, and then take new orders. I asked how P-V work in my previous post here. I don't think it has anything to do with \n consuming? I tried all kinds of combination of wait(), but none work. Where did I make a mistake? The main part is here: //Producer process if(pid > 0) { while(1) { printf("0"); P(emptyShelf); // waiter as P finds no items on shelf; P(mutex); // has permission to use the shelf waiter_as_producer(); V(mutex); // cooker now can use the shelf V(orderOnShelf); // cooker now can pickup orders wait(); printf("2"); P(pizzaOnShelf); P(mutex); waiter_as_consumer(); V(mutex); V(emptyShelf); printf("3 "); } } if(pid == 0) { while(1) { printf("1"); P(orderOnShelf); // make sure there is an order on shelf P(mutex); //permission to work cooker_as_consumer(); // take order and put pizza on shelf printf("return from cooker"); V(mutex); //release permission printf("just released perm"); V(pizzaOnShelf); // pizza is now on shelf printf("after"); wait(); printf("4"); } } So I imagine this is the execution path: enter waiter_as_producer, then go to child process (cooker), then transfer the control back to parent, finish waiter_as_consumer, switch back to child. The two waits switch back to parent (like I said I tried all possible wait() combination...).

  • Socket read() hangs for a while when there is no data to read.

    - by janesconference
    Hi' I'm writing a simple http port forwarder. I read data from port 80, and pass the data to my lighttpd server, on port 8080. As long as I write() data on the socket on port 8080 (forwarding the request) there's no problem, but when I read() data from that socket (forwarding the response), the last read() hangs a lot (about 1 or 2 seconds) before realizing there's no more data and returning 0. I tried to set the socket to non-blocking, but this doesn't work, as sometimes it returns EWOULDBLOCKING even if there's some data left (lighttpd + cgi can be quite slow). I tried to set a timeout with select(), but, as above, a slow cgi could timeout the socket when there's actually some data to transmit. How would you do?

  • ImageMagick - how to enforce min/max heights/widths?

    - by Henryh
    Using ImageMagick, how can I resize an image to have a minimum: height of 150px width of 200px and also have a maximum: height of 225px width of 275px UPDATE: In case it helps, here's a further explanation of what I'm experiencing. I have a buch of images with all different ratio dimensions. Some images have 1:5 height/width ratios. Some have 5:1 height/width ratios. So that I want to do is set that a minimum height/width size for the image but also don't want the image size to be larger than a particular size. If I need to apply white padding to an image to make it fit within my constraint so that I don't have to distort the image, I'd like to do so.

Basically I want to get the details from FILE 1 and compare with FILE2 (master list) . Example : A1 in FILE2 was not available in FILE1 , so in output file we have “-“ for 1st three fields and rest from FILE2 . Now, we have A11 and we got the detail in FILE1. So we write details of A11 from both File 1 & 2

  • How to run a shell command and selectively ignore the status?

    - by Walter Nissen
    I've got a shell script that I would like to stop with an error on nonzero status most of the time, but in some cases I want to ignore it. For example: #!/bin/tcsh -vxef cp file/that/might/not/exist . #Want to ignore this status cp file/that/might/not/exist . ; echo "this doesn't work" cp file/that/must/exist . #Want to stop if this status is nonzero

  • what does the @ symbol mean in ls -l directory listing?

    - by Andrew Arrow
    When I run ls -l on my mac I see two .yml files: -rw-r--r-- 1 aa staff 6 Apr 15 05:50 s1.yml -rw-r--r--@ 1 aa staff 362 Apr 15 05:49 s3.yml same owner, same permissions but one has a @ at the end of the permisions. The one with the @ shows up in my editor, the one without does not. So there must be some significance. How can I turn on the @ for the file without it? I selected the files in the finder and did get info and everything looks identical between the two files.

  • Sourcing a shell script, while running with sudo

    - by WishCow
    I would like to write a shell script that sets up a mercurial repository, and allow all users in the group "developers" to execute this script. The script is owned by the user "hg", and works fine when ran. The problem comes when I try to run it with another user, using sudo, the execution halts with a "permission denied" error, when it tries to source another file. The script file in question: create_repo.sh #!/bin/bash source colors.sh REPOROOT="/srv/repository/mercurial/" ... rest of the script .... Permissions of create_repo.sh, and colors.sh: -rwxr--r-- 1 hg hg 551 2011-01-07 10:20 colors.sh -rwxr--r-- 1 hg hg 1137 2011-01-07 11:08 create_repo.sh Sudoers setup: %developer ALL = (hg) NOPASSWD: /home/hg/scripts/create_repo.sh What I'm trying to run: user@nebu:~$ id uid=1000(user) gid=1000(user) groups=4(adm),20(dialout),24(cdrom),46(plugdev),105(lpadmin),113(sambashare),116(admin),1000(user),1001(developer) user@nebu:~$ sudo -l Matching Defaults entries for user on this host: env_reset User user may run the following commands on this host: (ALL) ALL (hg) NOPASSWD: /home/hg/scripts/create_repo.sh user@nebu:~$ sudo -u hg /home/hg/scripts/create_repo.sh /home/hg/scripts/create_repo.sh: line 3: colors.sh: Permission denied So the script is executed, but halts when it tries to include the other script. I have also tried using: user@nebu:~$ sudo -u hg /bin/bash /home/hg/scripts/create_repo.sh Which gives the same result. What is the correct way to include another shell script, if the script may be ran with a different user, through sudo?

  • Hudson trigger builds remotely gives a forbidden 403 error

    - by Ritesh M Nayak
    I have a shell script on the same machine that hudson is deployed on and upon executing it, it calls wget on a hudson build trigger URL. Since its the same machine, I access it as http://localhost:8080/hudson/job/jobname/build?token=sometoken Typically, this is supposed to trigger a build on the project. But I get a 403 forbidden when I do this. Anybody has any idea why? I have tried this using a browser and it triggers the build, but via the command line it doesn't seem to work. Any ideas?

  • Howto plot two cumulative frequency graph together

    - by neversaint
    I have data that looks like this: #val Freq1 Freq2 0.000 178 202 0.001 4611 5300 0.002 99 112 0.003 26 30 0.004 17 20 0.005 15 20 0.006 11 14 0.007 11 13 0.008 13 13 ...many more lines.. Full data can be found here: http://dpaste.com/173536/plain/ What I intend to do is to have a cumulative graph with "val" as x-axis with "Freq1" & "Freq2" as y-axis, plot together in 1 graph. I have this code. But it creates two plots instead of 1. dat <- read.table("stat.txt",header=F); val<-dat$V1 freq1<-dat$V2 freq2<-dat$V3 valf1<-rep(val,freq1) valf2<-rep(val,freq2) valfreq1table<- table(valf1) valfreq2table<- table(valf2) cumfreq1=c(0,cumsum(valfreq1table)) cumfreq2=c(0,cumsum(valfreq2table)) plot(cumfreq1, ylab="CumFreq",xlab="Loglik Ratio") lines(cumfreq1) plot(cumfreq2, ylab="CumFreq",xlab="Loglik Ratio") lines(cumfreq2) What's the right way to approach this?

  • Grep expression with special file names

    - by user2919185
    i am a real beginner in csh/tcsh scripting and that's why i need your help. The problem is I have to go through some regular files in directories and find those files, that have their own name in its content. In the following piece of script is cycle in which I am going through paths and using grep to find the file's name in its content. What is surely correct is $something:q - is array of paths where i have to find files. The next variable is name in which is only name of current file. for example: /home/computer/text.txt (paths) and: text.txt (name) And my biggest problem is to find names of files in their content. It's quite difficult for me to write correct grep for this, cause the names of files and directories that i am passing through are mad. Here are some of them: /home/OS/pocitacove/testovaci_adresar/z/test4.pre_expertov/!_1 /home/OS/pocitacove/testovaci_adresar/z/test4.pre_expertov/dam/$user/:e/'/-r /home/OS/pocitacove/testovaci_adresar/z/test3/skusime/ taketo/ taketo /home/OS/pocitacove/testovaci_adresar/z/test4.pre_expertov/.-bla/.-bla/.a=b /home/OS/pocitacove/testovaci_adresar/z/test4.pre_expertov/.-bla/.-bla/@ /home/OS/pocitacove/testovaci_adresar/z/test4.pre_expertov/.-bla/.-bla/: /home/OS/pocitacove/testovaci_adresar/z/test4.pre_expertov/.-bla/.-bla/'ano' foreach paths ($something:q) set name = "$paths:t" @ number = (`grep -Ec "$name" "$paths"`) if ($number != 0) then echo -n "$paths " echo $number endif @ number = 0 end

  • Checking if a directory contains files

    - by ionn
    How do I check if a directory contains files? Something similar to this: if [ -e /some/dir/* ]; then echo "huzzah"; fi; but which works if the directory contains one or several files (the above one only works with exactly 0 or 1 files).

  • Fixing permissions after FTPing ASP.NET code to a Linux system

    - by dnord
    First off, I'm running Mono to run ASP.NET on Linux, but that's not the question. It appears that, every time I clear out my application directory and upload, I have to go back in and fix the permissions. What I'm doing is chmod -R -c 755 /var/www/* ...and there are two questions. What's the deal with having to do this every time I FTP? Feels flaky. Is there a better permissions set than 755? Do I want different permissions for the /bin directory? Or can I fix this all with one fell swoop of chown?

  • How to determine what user and group a Python script is running as?

    - by Chirael
    I have a CGI script that is getting an "IOError: [Errno 13] Permission denied" error in the stack trace in the web server's error log. As part of debugging this problem, I'd like to add a little bit of code to the script to print the user and (especially) group that the script is running as, into the error log (presumably STDERR). I know I can just print the values to sys.stderr, but how do I figure out what user and group the script is running as? (I'm particularly interested in the group, so the $USER environment variable won't help; the CGI script has the setgid bit set so it should be running as group "list" instead of the web server's "www-data" - but I need code to see if that's actually happening.)

  • Navigating multiples files vi editor

    According to http://www.lagmonster.org/docs/vi2.html the command :p would make vi go to the previous file. Unfortunately, this isn't working for me. However :n works and goes to the next page. What should I use to go to the previous file? For :p I get the message, Hit Return to continue and it stays in the same page. Thanks. Edit: I am sshing to an AIX box and using the vi in Ksh if that helps.

  • Loading zsh as the default shell in gnu screen

    - by joel
    Hello, Im using KUbuntu 10.04 (Lucid Lynx). I have installed zsh and screen. I have set zsh as the default shell, by setting Command to zsh in Settings-Edit Current Profile of the terminal. But,when i launch screen,the bash shell is loaded. If i run the command zsh, then zsh starts but the following message is displayed: "/home/joel/.zshrc:36: Can't add module parameter `mapfile': parameter already exists" Also,zsh is invoked for only the current screen instance and i have to invoke it manually again for other instances. So,is there any way to make screen load zsh by default and invoke it automatically for every instance ? Thank You
