  • remotely running find -exec options

    - by Michael Merchant
    I'm trying to setup a bash process for deploying my django project onto a linux server. Through cygwin, I'm running a script that is calling scp to copy my files over. Is there a similar command to delete *.pyc files. As of now, I've only been able to accomplish this locally after using ssh with: find . -name "*.pyc" -exec rm -rf {} \; I'm looking for some kind of command to call remotely that would be equivalent.

  • Unique Features of bash compared to zsh

    - by Tim
    I have been a zsh user for quite some time (before that tcsh and before that csh). I am quite happy with it, but was wondering if there are any compelling features of bash that do not exist in zsh. And conversely, are there zsh features which do not exist in bash. My current feel is that bash is better: If you are familiar with it already and don't want to learn new syntax. It is going to exist on most all *nix machines by default, whereas zsh may be an extra install. Not trying to start a religious battle here, which is why I'm just looking for features which exist in only one of the shells.

  • Using SSH to find access to a problematic script in logs of multiple domains

    - by Hanan Cohen
    I run several (~20) sites on a Dreamhost VPS. Lately I max my memory allocation for the VPS and I want to find the problem. I would like to have an SSH script that will scan all the log files of all the domains and show me what object (image, php script etc) gets lots of calls. It will count the calls in each /logs/*/http/access.log, do an descending sort and show me the top 10 across domains. But I don't know how to do that. Can it be done? Can anyone suggest a script that will do that? Thanks. (Cross posted to Stack Overflow)

  • Bash if statement equal output from last command

    - by mYzk
    I am trying to equal something from last command with bash if statement: #!/bin/bash monit status if [ "status" != "error" ]; then echo -e "hostname\ttest\t0\t0" | /usr/sbin/send_nsca -H hostname -c /etc/send_nsca.cfg exit 1; fi Even if the monit status gives out status = online with all services it runs the echo command. I can not figure out how to make the if statement match the status of monit status output.

  • How to make new file permission inherit from the parent directory?

    - by Wai Yip Tung
    I have a directory called data. Then I am running a script under the user id 'robot'. robot writes to the data directory and update files inside. The idea is data is open for both me and robot to update. So I setup the permission and owner group like this drwxrwxr-x 2 me robot-grp 4096 Jun 11 20:50 data where both me and robot belongs to the 'robot-grp'. I change the permission and the owner group recursively like the parent directory. I regularly upload new files into the data directory using rsync. Unfortunately, new files uploaded does not inherit the parent directory's permission as I hope. Instead it looks like this -rw-r--r-- 1 me users 6 Jun 11 20:50 new-file.txt When robot tries to update new-file.txt, it fails due to lack of file permission. I'm not sure if setting umask helps. In anycase the new files does not really follow it. $ umask -S u=rwx,g=rx,o=rx I'm often confounded by Unix file permission. Do I even have a right plan? I'm using Debian lenny.

  • How to lock screen in linux before hibernating?

    - by Emanuel Ey
    So when i hibernate my laptop the screen doesn't lock automatically. To solve this i've changed /etc/acpi/powerbtn.sh to contain: su - myUsername -c "gnome-screensaver-command -l" sudo pm-hibernate exit 0 When running this file from a command line it works as intended (ie, lock the screen and then hibernate). Unfortunately, when pressing the power button, it still just hibernates without locking the screen -what am I missing? EDIT: I've added the line whoami>>~/Desktop/test.txt to verify which user is executing the /etc/acpi/powerbtn.shscript. When pressing the power button, the file test.txt is created, but is empty. From this i conclude that the script is in fact being called when pressing the power button. What i do not understand is how the output of whoami can be empty...

  • My PowerShell functions do not appear to be used

    - by Frank
    Hi there, I have a ps1 script in which I define 2 functions as such: function Invoke-Sql([string]$query) { Invoke-Sqlcmd -ServerInstance $Server -Database $DB -User $User -Password $Password -Query $query } function Get-Queued { Invoke-Sql "Select * From Comment where AwaitsModeration = 1" } I then call the ps1 file by typing it in (it's in a folder in the path, and autocompletion works) However, I cannot start using the functions. I am confused, because when I copy / paste the functions into the console, all is fine and they work. I also have a function defined in my profile, and it works. Where am I thinking wrong, why doesn't it work what I'm trying to do?

  • Gnome 3 gdm fails to start after preupgrade from fedora 14 to 15

    I'm not able to boot fedora 15 in runlevel 5. After all services start, when the login screen should appear, gdm just show a mouse waiting cursor and keeps restarting itself.

  • bash script with permanent ssh connection

    - by samuelf
    I use a bash script which runs /usr/bin/ssh -f -N -T -L8888:127.0.0.1:3306 [email protected] However, when I run the bash script, it waits.. I see the connection coming up but the script doesn't exit.. it's like it's waiting for the SSH process to finish, because when I manually kill it the bash script finishes as well. Any ideas how to resolve this? UPDATE: I have croned this script.. and the cron process is the one that becomes a zombie.. the actual scripts runs just fine, sorry about that, with ps -auxf I get: root 597 0.0 0.7 2372 912 ? Ss Jul12 0:00 cron root 2595 0.0 0.8 2552 1064 ? S 02:09 0:00 \_ CRON 1001 2597 0.0 0.0 0 0 ? Zs 02:09 0:00 \_ [sh] <defunct> 1001 2603 0.0 0.0 0 0 ? Z 02:09 0:00 \_ [cron] <defunct> and when I kill the ssh the defuncts disappear.. why would they become defunct?

  • xargs command works on ubuntu, but not mac

    I have the following line of code that I use to update my personal date variable in my projects to today's current date. This line works in Ubuntu's terminal, but the Mac terminal seems to be far behind. Unfortunately, I copied this snippet from some site, so I'm not sure how it exactly works. Suggestions? grep -ilr --exclude=revar.sh --exclude=README.md "[DATE]" * | grep -v .git | xargs -i@ sed -i "s/\[DATE\]/${today}/g" @

  • Installing Ruby 1.9.3 OSX 10.7.4 breaks after altering PATH

    - by R V
    I was having trouble installing ruby 1.9.3-p194 from ruby 1.8.7 on my mac osx 10.7.4. I have was trying to fix my homebrew after running "brew doctor" and got the message of "/usr/bin occurs before /usr/local/bin This means that system-provided programs will be used instead of those provided by Homebrew. The following tools exist at both paths: c++-4.2 cpp-4.2 erb g++-4.2 gcc-4.2 gcov-4.2 gem i686-apple-darwin11-cpp-4.2.1 i686-apple-darwin11-g++-4.2.1 i686-apple-darwin11-gcc-4.2.1 irb rake rdoc ri ruby testrb" I fixed it by entering the following, which I found on another stackoverflow answer: export PATH="/usr/local/bin:/usr/local/sbin:~/bin$PATH" Lo and behold! when I typed that ruby updates to 1.9.3-p194. Ruby files seem to compile and run just fine. However, afterward, my navigation around terminal is messed up severely. For instance I can't do the command "open example_file.html" and have the file pop up in Chrome, instead I get the error: "-bash: open: command not found" Also, when I change directory, I get an error, inputting "$ cd desktop" yields the output, "-bash: dirname: command not found" but the directory does then changes... strange. When I exit out of a terminal window all this resets. I'm back to Ruby 1.8.7, have to use the PATH command again to update to 1.9.3, command line navigation gets broken again. Any guidance on how to remedy so I can use 1.9.3-p194 and also have normal terminal navigation would be greatly appreciated.

  • Explanation of command to uppercase the first letter of a filename

    - by hazielquake
    I'm trying to learn to rename files with the command line, and after browsing around a lot of pages I finally found a command that uppercases the first letter of a file, but the problem is that I want to understand the meaning of each command. The command is: for i in *; do new=`echo "$i" | sed -e 's/^./\U&/'`; mv "$i" "$new";done I understand the 'for' kinda... but not the 'echo' or '`' and especially the sed command. if someone has a little patience to explain the meaning of each thing that'd be awesome! Thanks!

  • Mac Terminal.app: Force '^C' to be printed when editing current prompt, then aborting it

    - by Stefan Lasiewski
    This is the opposite of Prevent “^C” from being printed when aborting editing current prompt. I'm using Bash. When I'm editing the commandline in Bash, and I hit Control-C to abort the commandline, the '^C' character does not display. I would like to see this character. I tried commands like stty -ctlecho and stty ctlecho (which I borrowed from the other question), but this didn't work for me. This behavior seems to be true with my environment on Ubuntu, CentOS and MacOSX. This only happens within Apple's Terminal.App. If I SSH to a remote Linux or FreeBSD box, then ^C is printed. So, this is clearly just a local setting. Update: Here is the output of stty -a, as requested by @quack quixote : $ stty -a speed 9600 baud; 41 rows; 88 columns; lflags: icanon isig iexten echo echoe -echok echoke -echonl echoctl -echoprt -altwerase -noflsh -tostop -flusho pendin -nokerninfo -extproc iflags: -istrip icrnl -inlcr -igncr ixon -ixoff ixany imaxbel iutf8 -ignbrk brkint -inpck -ignpar -parmrk oflags: opost onlcr -oxtabs -onocr -onlret cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow -dtrflow -mdmbuf cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>; eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W; After typing stty sane, stty -a will output the following.

  • Strange strace and setuid behaviour: permission denied under strace, but not running normally.

    - by Autopulated
    This is related to this question. I have a script (fix-permissions.sh) that fixes some file permissions: #! /bin/bash sudo chown -R person:group /path/ sudo chmod -R g+rw /path/ And a small c program to run this, which is setuided: #include "sys/types.h" #include "unistd.h" int main(){ setuid(geteuid()); return system("/path/fix-permissions.sh"); } Directory: -rwsr-xr-x 1 root root 7228 Feb 19 17:33 fix-permissions -rwx--x--x 1 root root 112 Feb 19 13:38 fix-permissions.sh If I do this, everything seems fine, and the permissions do get correctly fixed: james $ sudo su someone-else someone-else $ ./fix-permissions but if I use strace, I get: someone-else $ strace ./fix-permissions /bin/bash: /path/fix-permissions.sh: Permission denied It's interesting to note that I get the same permission denied error with an identical setup (permissions, c program), but a different script, even when not using strace. Is this some kind of heureustic magic behaviour in setuid that I'm uncovering? How should I figure out what's going on? System is Ubuntu 10.04.2 LTS, Linux 2.6.32.26-kvm-i386-20101122 #1 SMP

  • Default prolog for all ZSH scripts?

    - by Igor Spasic
    I have a file that contains several helper functions, meant to be used only in other ZSH scripts. I do not want them to be loaded with my profile. To make these functions available in my script, I would need to source this file. Is it somehow possible to have automatic prolog script (or pre-script) loaded before all my ZSH scripts? My current idea is to alias -s zsh extension to custom function that those all this for me: concatenate prolog file and current script calls zsh with such modified input but for now I am somehow not able to do this (haven't sleep for almost a day). Please, does anyone have a working solution?
