  • disown a process in ksh

    - by fahdshariff
    The "disown" command works in bash, but not in ksh. If I have started a process in ksh, how can I "disown" it, so I can exit my shell. (I know about nohup, but the process has already started!)

  • How to count differences between two files on linux?

    - by Zsolt Botykai
    Hi all, I need to work with large files and must find differences between two. And I don't need the different bits, but the number of differences. For the differ rows I come up with diff --suppress-common-lines --speed-large-files -y File1 File2 | wc -l And it works, but is there a better way to do it? And how to count the exact number of differences (with standard tools like bash, diff, awk, sed some old version of perl)? Thanks in advance

    - by Steve

I get the same permission denied message. Any clues as to how to fix this?

Please let me know the correct alternative for this line. cur_major=$((0x`stat -c %t $dev 2>/dev/null`)) The busybox throws in an error saying "0x" syntax error, which i understand is the problem with the syntax of this line. Thanks in advance

  • "git pull" broken

    - by Ovid
    I recently upgraded my MacBook Pro to Snow Leopard and "git pull" returns: rakudo $ git pull git: 'pull' is not a git-command. See 'git --help' Did you mean this? shell rakudo $ git-pull -bash: git-pull: command not found I've tried reinstalling via macports, but to no avail. Then I saw this rakudo $ git --exec-path /Users/ovid/libexec/git-core That surprised me as that directory does not exist, nor has it ever existed. Google is not helping here. Hopefully you can :)

  • Youtube Downloader

    - by Erik Persson
    Hi, A time ago I had a script who got the flv-file from a specified youtube-video, which now is broken due to changes at their website. I am wondering if Youtube may have an API to download the flv-file, where can I find it in that case? Have anyone build an own script, may someone wanna help be building it? Is there any scripts in any other languages such as shell/bash that works? :) Best regards, Erik Persson

  • How can this C and PHP programmer learn Ruby and Rails?

    - by Winston
    I came from a C, php and bash background, it was easy to learn because they all have the same C structure, which I can associate with what I already know. Then 2 years ago I learned Python and I learned it quite well, Python is easier for me to learn than Ruby. Then since last year, I was trying to learn Ruby, then Rails, and I admit, until now I still couldn't get it, the irony is that those are branded as easy to learn, but for a seasoned programmer like me, I just couldn't associate it with what I learned before, I have 2 books on both Ruby and Rails, and when I'm reading it nothing is absorbed into my mind, and I'm close to giving up... In ruby, I'm having a hard time grasping the concepts of blocks, and why there's @variables that can be accessed by other functions, and what does $variable and :variable do? And in Rails, why there's function like this_is_another_function_that_do_this, so thus ruby, is it just a naming convention or it's auto-generated with thisvariable _can_do_this_function. I'm still puzzled that where all those magic concepts and things came from? And now, 1 year of trying and absorbing, but still no progress... Edit: To summarize: How can I learn about blocks, and how can it be related to concepts from PHP/C? Variables, what does does it mean when a variable is prefixed with: @ $ : "Magic concepts", suchs as rails declarations of Records, what happens behind the scenes when I write has_one X OK so, bear with me with my confusion, at least I'm honest with myself, and it's over a year now since I first trying to learn ruby, and I'm not getting younger.. so I learned this in Bash/C/PHP solve_problem($problem) { if [ -e $problem == "trivial" ]; then write_solution(); else breakdown_problem_into_N_subproblems(\; define_relationship_between_subproblems; for i in $( command $each_subproblem ); do solve_problem $i done fi } write_solution(problem) { some_solution=$(command <parameters> "input" | command); command | command $some_solution > output_solved_problem_to_file } breakdown_problem_into_N_subproblems($problems) { for i in $problems; do command $i | command > i_can_output_a_file_right_away done } define_relationship_between_subproblems($problems) { if [ -e $problem == "relationship" ]; then relationship=$(command; command | command; command;) elsif [ -e $problem == "another_relationship" ]; relationship=$(command; command | command; command;) fi } In C/PHP is something like this solve_problem(problem) { if (problem == trivial) write_solution; else { breakdown_problem_into_N_subproblems; define_relationship_between_subproblems; for (each_subproblem) solve_problems(subproblem); } } And now, I just couldn't connect the dots with Ruby, |b|{ blocks }, using @variables, :variables, and variables_with_this_things..

  • Running shell scripts with sudo through my Rails app

    - by nfm
    In my Rails app, I have some functionality that interfaces with the server's OS. I've written a bash script, put it in my lib/ subdirectory, and can run it from my controller. However, some functionality of the script requires superuser privileges. What is the most sane way to run this script securely? It is being passed arguments from a web form, but should only be able to be called by authenticated (and trusted) users.

  • "Hello World" in less than 20 bytes

    - by xelurg
    We have had an interesting competition once, where everyone would write their implementation of hello world program. One requirement was that is should be less than 20 bytes in compiled form. the winner would be the one whose version is the smallest... What would be your solution? :) Platform: 32bit, x86 OS: DOS, Win, GNU/Linux, *BSD Language: Asm, C, or anything else that compiles into binary executable (i.e. no bash scripts and stuff ;)

    - by Arkapravo
    Dear Friends ! I have very definitively come across the 'simulating a 6-faced die' (which produces a random integer between 1 and 6, all outcomes are equally probable) in Java, Python, Ruby and Bash. However, I am yet to see a similar program in Ada. Has anyone come across one ? Kind regards Arkapravo

  • Is it possible for a java.lang.Process to inherit the environement variables from another java.lang.

    - by Eric Leung
    I am trying to use groovy to do shell scripting on unix, but I am not having any luck having one process retain the environment variables changed by another process. For example, def p1 = ["bash", "-c", "source /some/setEnv.sh"].execute() Now, I would like a second process, p2, to inherit the environment variables that was set in p1. How can I do this? I don't see anything in java.lang.Process or its groovy extension that would spit out the environment variables after the process has executed.
