Looking to use kill -9 instead of killall using process name.
Is there a way I can grep or awk the pid of a given process name/s then kill it will kill -9 ?
killall fails a lot for me.
I'm looking to script this for numerous remote machines.
Process name will be one of three.
I want to use something like:
sshpass -p 'password' ssh -n $user@$hostname "one liner to use kill -9"
Any ideas?
So, I need to grep the text after a string like
Motherboard P/N : XXXXXXXXXX
Where XXXXXXXXX is the text I want.
I don't want the Motherboard P/N :
I can't seem to make awk, cut, sed or anything work well with the P/N
Any ideas?
I have a mysql table with some unique constraints. I have a script that asks some questions, and then inserts the answers into the mysql table.
I don't know how to tell the script to do something else if a duplicate entry exists.
I'd like to give the option to remove the entry and add the new, or return to the start begin the script again.
Hope that makes sense.

I have this script, it's cut down, but fine for this example:
#!/bin/bash
source /home/user/configs/config-file
while read host; do
find /home/user/configs/$host.cfg -type f -exec sed -i 's/value=./#value= /g' {} \;
echo "value="$value >> /home/user/configs/$host.cfg
done < hosts.list
The hosts.list file contains a list of hostnames
XYZ123
ABC567
LIN999
etc. The config-file contains entires like:
value=ZZZZZZZ
othervalue=YYYYYYY
3rdvalue=XXXXXXX
Full script makes use of all values, this example just uses value Hope that make sense.
Running this script creates a file with each hostname from the hosts.list file, but with a ? at the end, so one would look like XYZ123?.cfg During the run process I see:
find: â/home/user/configs/XYZ123\r.cfgâ: No such file or directory
Think I should use sed, but can't get it down correctly.
I have a folder full of text files. They're all constructed the same, with a list of variables, e.g.
NAME=John
AGE=30
CODE=xyz
I need to look at all files, and modify the value of a variable, like CODE, to something.
So, file1.txt - change CODE=xyz to CODE=123
file2.txt - change CODE=foo to CODE=123
What I change it TO will be the same for all files.
Is sed the best for this?
I have, what I think, is a complex task.
I have 1 machine we'll call a server and a whole bunch of other machines, hostX. They all run Ubuntu 16.04 server. Each host runs a simple bash script at startup, but that script currently has hard coded values. I would like to use variables within that script, but the variable values should be stored in files/a file on the server, allowing me to change values in one central place and affect a host, or a group of hosts. I'm happy that I'll have to either reboot, or restart the script on each host after a change, that's no problem. The issue I have is that I don't know how to use a variable from a remote machine, all I can find is info about running a script on a remote machine. I want it to run locally, but pull info from the remote.
So here's my work flow, in my head.
Host1 boots and looks at the contents of host1.cfg located on the server.
host1.cfg looks like this:
NAME=John
ADDRESS='10 The High Street'
AGE=25
Host1 runs:
echo server:$HOSTNAME.cfg:$NAME & $ADDRESS & $AGE
Or maybe have a central HOST.CFG file with:
[HOST1]
NAME=John
ADDRESS='10 The High Street'
AGE=25
[HOST2]
NAME=Mike
ADDRESS='30 The Avenue'
AGE=80
Does that make sense?
I'm looking to list all files in a folder:
ABC123.cfg
XYZ456.cfg
EFG999.cfg
The file names, without the .cfg relate to a remote server name, ABC123 etc.
I want to copy a couple of files to each of the remote servers.
So, look up the filenames, but take the name without the .cfg. Then
scp filename.txt username@ABC123:/home/username/
For each remote server, overwriting the destination file if exists.
Each remote server uses the same username and password.
Can I use a password in the scp command?
I have a number of Ubuntu 14.04 clients, and Ubuntu 14.04 server running local DNS. Currently the DHCP server is a router - going to change this.
How can I register the clients, either static or DHCP addressed, to the local DNS server?
I would like to reference the clients by their hostname.
I have this in my DNS conf files:
/etc/bind/named.conf:
include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";
include "/etc/bind/named.conf.default-zones";

};

allow-transfer { 192.168.51.251; };

IP address of this DNS server is 192.168.51.250 I have the forwarders set up OK.
On a client:
/etc/network/interfaces:
auto enp0s31f6
iface enp0s31f6 inet static
host-name manic2
address 192.168.51.50
netmask 255.255.255.0
network 192.168.51.0
gateway 192.168.51.201
dns-nameservers 192.168.51.250
dns-search est1.lan
dns-domain est1.lan
In a client using DHCP I have
send host-name = manic
in the /etc/dchp/dhclient.conf file.
What would I be missing?
