I am using ejabberd 2.1 for my chat application.We have used multi user chat rooms.I want to clear out all my existing chat rooms from ejabberd.Is it possible from the admin part.Any ejebberdctl command available for this?
Help is highly appreciable
I believe that
ejabberdctl muc-purge 0
May fullfill your need.
The man entry for this command is the following:
ejabberdctl muc-purge days
Destroy MUC rooms with zero activity (no messages in history) in the
last days days.
I used that for list and delete all muc rooms in the server
sudo ejabberdctl muc_online_rooms global | sed -e 's/#/ /g' | xargs -n 2 -I {} bash -c 'sudo ejabberdctl destroy_room {}'
In my case i need use sudo, if you dont need just remove it.

I would like to download all pdf files linked on a website using wget on Mac OS (zsh).
I have tried:
wget -r -p -k --random-wait --limit-rate=50k -A .pdf -erobots=off https://unfccc.int/process-and-meetings/bodies/constituted-bodies/executive-committee-of-the-warsaw-international-mechanism-for-loss-and-damage-wim-excom/task-force-on-displacement/implementation-updates-task-force-on-displacement\#eq-1
and I have also added the following options to no avail:
--span-hosts
--no-check-certificate
--no-cookies
-H
The error is always the same:
no-follow attribute found in unfccc.int/process-and-meetings/bodies/constituted-bodies/executive-committee-of-the-warsaw-international-mechanism-for-loss-and-damage-wim-excom/task-force-on-displacement/implementation-updates-task-force-on-displacement. Will not follow any links on this page
First make sure you has permission to crawl the pages, I'm not gonna be responsible for bad thing happend to you or anyone after bypassing the robot no-follow attribute !
The tricks to ignore all restrictions and be a bad crawler bot you just need to include :
-e robots=off on your command.
Yes, you've included it on your commands but you got some typos !
Just like #x00 say it need to be -e robots=off instead of -erobots=off.
I Don't know why #x00 doesn't answer the question with his answer :/
Note :
For x00, if you want to me to delete my answer because its nearly similar with yours comment , just command under my answer and i will delete it for you anytime !
I want to install Anaconda through EasyBuild. EasyBuild is a software to manage software installation on clusters. Anaconda can be installed with sh Anaconda.sh.
However, after running I have to accept the License agreement and give the installation location on the command line by entering <Enter>, yes <Enter>, path/where/to/install/ <Enter>.
Because this has to be installed automatically I want to do the accepting of terms and giving the install location in one line. I tried to do it like this:
sh Anaconda.sh < <(echo) >/dev/null < <(echo yes) >/dev/null \
< <(echo /apps/software/Anaconda/1.8.0-Linux-x86_64/) > test.txt
From the test.txt I can read that the first echo works as <Enter>, but I can't figure out how to accept the License agreement, as it sees it now as not sending yes:
Do you approve the license terms? [yes|no]
[no] >>> The license agreement wasn't approved, aborting installation.
How can I send the yes correctly to the script input?
Edit: Sorry, I missed the part about having to enter more then one thing. You can take a look at writing expect scripts. thegeekstuff.com/2010/10/expect-examples. You may need to install it however.
You could try piping with the following command: yes yes | sh Anaconda.sh. Read the man pages for more information man yes.
Expect is a great way to go and probably the most error proof way. If you know all the questions I think you could do this by just writing a file with the answers in the correct order, one per line and piping it in.
That install script is huge so as long as you can verify you know all the questions you could give this a try.
In my simple tests it works.
I have a test script that looks like this:
#!/bin/sh
echo -n "Do you accept "
read ANS
echo $ANS
echo -n "Install path: "
read ANS
echo $ANS
and an answers file that looks like this:
Y
/usr
Running it like so works... perhaps it will work for your monster install file as well.
cat answers | ./test.sh
Do you accept Y
Install path: /usr
If that doesn't work then the script is likely flushing and you will have to use expect or pexpect.
Good luck!
Actually, I downloaded and looked at the anaconda install script. Looks like it takes command line arguments.
/bin/bash Anaconda-2.2.0-Linux-x86_64.sh -h
usage: Anaconda-2.2.0-Linux-x86_64.sh [options]
Installs Anaconda 2.2.0
-b run install in batch mode (without manual intervention),
it is expected the license terms are agreed upon
-f no error if install prefix already exists
-h print this help message and exit
-p PREFIX install prefix, defaults to /home/cody.stevens/anaconda
Use the -b and -p options...
so use it like so:
/bin/bash Anaconda-2.2.0-Linux-x86_64.sh -b -p /usr
Also of note.. that script explicitly says not to run with '.' or 'sh' but 'bash' so they must have some dependency on a feature of bash.

I am on Linux Centos OS. I understand that using "rpm -qa" gives a lot of install paths for the corresponding package. However, I need just the base package install location for the package. Is there any way/command/option in Linux to retrieve the same? My code snippet is to retrieve list of running services and the corresponding package installed is as below:-
for i in $(service --status-all | grep -v "not running" | grep -E running\|stopped | awk '{print $1}');
do
packagename=$(rpm -qf /etc/init.d/$i)
servicestatus=$(service --status-all | grep $i | awk '{print $NF}' | sed 's/...//g' | sed 's/.//g');
echo $tdydate, $(ip route get 8.8.8.8 | awk 'NR==1 {print $NF}'), $i, $packagename, $servicestatus > "$HOME/MyLog/running_services.csv"
done
Now, I need to also get the corresponding package install location as well which is hosting the running service. Is there a way to retrieve this as well along with getting the package names. Please confirm.
Thanks in advance for extending help.
Regards.
Okay, with your answer to my question in the comments, which is much clearer to me than you initial question...
Hi, basically what i need is:- I get a list of all installed services on my Centos using service --status-all. Now, for each service, I need to know the corresponding application package location on linux.
...I'll propose this (tested here on CentOS 6.6):
#!/bin/bash
for i in `chkconfig --list | awk '{ print $1}'`; do
service $i status >/dev/null 2>&1
if [ $?==0 ]; then
rpm -qf /etc/init.d/$i
fi
done | sort | uniq
That spits out all rpm names of the services which are currently running.
A bit more detail as to why your current approach is not going to work:
service --status-all is not going to return information which can be parsed reliably. For example, the output on a VM here:
acpid (pid 872) is running...
auditd (pid 789) is running...
Stopped
cgred is stopped
Checking for service cloud-init:Checking for service cloud-init:Checking for service cloud-init:Checking for service cloud-init:crond (pid 1088) is running...
ip6tables: Firewall is not running.
iptables: Firewall is not running.
Kdump is not operational
mdmonitor is stopped
netconsole module not loaded
Configured devices:
lo eth0
Currently active devices:
lo eth0
ntpd (pid 997) is running...
master (pid 1076) is running...
rdisc is stopped
restorecond is stopped
rsyslogd (pid 809) is running...
sandbox is stopped
saslauthd is stopped
openssh-daemon (pid 988) is running...
Some services don't even return their name (third line). Some say stopped, others not running. If you parse the first column of chkconfig --list you know all the service names, which correspond to files in /etc/init.d. Then you can query their status individually and read the return code ($?), which is 0 for running services (or generally for success in the Unix/Linux world), 1 or higher for not running or not installed or incomplete/malfunctioning services.
Armed with names in /etc/init.d/ you can then query the owning package with rpm -qf /etc/init.d/<servicename> and get exactly what I think you were looking for.
Edit: added | sort | uniq after the loop, because some packages contain multiple services, like for example cloud-init, which creates four different services on CentOS. So you sort the list, then make sure you only get distinct (uniq) names back.
Works for me:
acpid-1.0.10-2.1.el6.x86_64
audit-2.3.7-5.el6.x86_64
cloud-init-0.7.5-10.el6.centos.2.x86_64
cronie-1.4.4-12.el6.x86_64

iputils-20071127-17.el6_4.2.x86_64

ntp-4.2.6p5-1.el6.centos.x86_64
ntpdate-4.2.6p5-1.el6.centos.x86_64
openssh-server-5.3p1-104.el6_6.1.x86_64
policycoreutils-2.0.83-19.47.el6_6.1.x86_64
postfix-2.6.6-6.el6_5.x86_64
rsyslog-5.8.10-9.el6_6.x86_64
udev-147-2.57.el6.x86_64
You are looking for --whatprovides instead of -qf (which does formatting).
Tweaking your example...
for i in $(chkconfig --list | awk '{ print $1}'); do service $i status >/dev/null 2>&1; if [ 0==$? ]; then echo -n "$i: "; rpm -q --whatprovides /etc/init.d/$i; fi; done | sort
FYI - this doesn't work on more modern systemd-based systems (CentOS 7).
Example on my Fedora 21 box:
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.
If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.

My script is creating a gt.txt file with abc user and writing some content into it. I have another script which is appending the content to the same file gt.txt but since it is being run as a different user, it is throwing an error.
What shall I do? Any possible solutions? Both are shell scripts but are run as different users.
I assume the error you are getting is 'permission denied'.
One option is to create a group, which both users can belong to, and assign group permissions to the file which allow group members to write to the file. Like this:
groupadd gtgroup
usermod -a -G gtgroup abcuser
usermod -a -G gtgroup defuser
chgrp gtgroup gt.txt
chmod g+rw gt.txt
You will need to issue most of those commands as root or via sudo. Also, groupadd and usermod commands may vary from one unix-like system to another.
If the file is being created from within the perl script, then you might have to perform the chgrp and chmod within the perl script. Use Perl chown and chmod for that.
I am trying to run the example on "http://gearman.org/getting_started" on Ubuntu in VirtualBox environment.
At first I tried to download an old version 0.16 by using apt-get install gearman-job-server, apt-get install gearman-tools and everything worked well. The server ran in the background, I was able to create 2 workers and verify that I can call them by creating a client.
I decided to download and compile the latest version, 1.1.6. Now, I am trying to do the same thing with the new version and I am having errors.
I run the server as admin:
sudo gearmand
The statement
gearadmin --getpid
seems to work - it returns me the process ID of the server. Thus, the server is running, and this answer is not relevant.
Now, I am adding a worker:
gearman -w -f wc -- wc -l
It seems to run.
Nevertheless,
gearadmin --workers
results in something that probably represents and empty list :
33 127.0.0.1 - :
.
(In version 0.16, I was able to see 2 lines, the second showing the registered function name.)
Attempting to run the client
gearman -f wc < /etc/passwd
results in
gearman: gearman_client_run_tasks : flush(GEARMAN_COULD_NOT_CONNECT) localhost:0 -> libgearman/connection.cc:671"
This might be the very same problem described in here - the port not specified, but I have no idea how to do it through the command line tool.
Any idea?
Ok, It looks like the answer in here was the key to success. Probably, the "getting started" section was not updated for a while. Indeed, one must specify a port explicitly for gearmand and gearman .
Server:
sudo gearmand -p 5000
Worker:
gearman -p 5000 -w -f wc -- wc -l
Client:
gearman -p 5000 -f wc < /etc/passwd
