General :: Script To Kill Process With Specific Character
Feb 11, 2011
I have a command that outputs as follows:
# lostjobs
user1 12983 1 0 Feb04 ? 00:00:00 dbr UT:msmenu
user1 18253 1 0 Feb09 ? 00:00:00 dbr UT:msmenu
[code]....
I know I can grab the ones with what I want to kill (which are the ones with question marks) with:
# lostjobs | grep ?
what I need to know is how can I loop through the results of the second one and kill them by id (the second column).

the process is mcelog. When I do as root kill -9 2323 which is pid of mcelog the process is not killed. I tried doing the same from top, press K and enter pid of mcelog. doing ps auwx | grep mcelog I see there are several results. I tried killing all of them like kill -9 2355 2341 3425 2345. But re-running the above commands still shows them as running. How else would I troubleshoot this to avoid restarting of the box.

I'm used to holding the left Alt and entering the ASCII character whenever I'm using an unknown keyboard configuration and want to type a special character. For example, Alt-092 makes a backslash (). That's on Windows. Is there a way to do this in Ubuntu ?
Note : I also want to be able to use this in console mode. That means I don't want a solution involving a software with a GUI.

I have a csv file that has around 3 million rows. I want to process this file so that it creates a new file that contains only the rows that have 2 characters or less in the first column column.At the moment i am using SQL Loader but its taking too long so im wondering whether this would be easier if done in Unix?

I thought 'killall' would work, but I need to provide the "command" to kill. I'm really looking for a command that will kill all processes that have a particular file/directory open. Currently, my script fails on an 'umount' because there are several processes that have this filesystem open. The command 'lsof' is a good tool to determine which processes have a filesystem open, but I don't really want to write a script that parses through the 'lsof' output to capture PSIDs. Is there a linux command that can kill all processes that may have a particular filesystem open?

Ctrl-c doesn't always work to kill the current process (for instance, if that process is busy in certain network operations). In that case, you just see "^C" by your cursor, and can't do much else.What's the easiest way to force that process to die now without losing my terminal?
Summary of answers below:Usually, you can Ctrl-z to put the process to sleep, and then do "kill -9 process-pid", where you find the process's pid with 'ps' and other tools.On Bash (and possibly other shells) you can do "kill -9 %1" (or '%N' in general) which is easier. If Ctrl-z doesn't work, you'll have to open another terminal and kill from there.

I have a big problem with one of my processes named "mbusd" ;it is an opensource modbus RTU/TCP gateway when I plug USB to serial convertor to it my laptop without this process linux makes virtual ttyUSB very fine and when I unplug it it removes except some times (SOME TIMES not all the times) that I run mbusd process to work with, at that time during mbusd process work when I unplug USB/serial converter the virtual ttyUSB does not disappear and mbusd does not exit too and it turnes in something like this when I get ps -aux: mbusd [defunc] at this time I can not even kill it with -9 or -15 signals and pluging back the converter does not solve the problem too and mbusd does not exit or start to run again.

I just bought an SSL cert and installed on my Apache server. When I restarted something went wrong so I had to change some config stuff and when I tried to restart apache for the second time I got this:
$ sudo apache2ctl start
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Problem is that apache isn't running. For some reason there is something hogging my tcp 80 port, preventing apache from starting properly. How do I fix this? Is there a way to "free" a port?

I am loading variables for cXtXdXsX disk names into a script, and at present I have only accounted for there being 3 characters from c to t. I need to change it to a variable recognition so that it can count any number of charcters such as c1t , c10t , or c100t.
I can then take that information and use it with the following string to strip off the lead characters so as to make the 3 in $substr either a variable or redirect to multiple occurrences of raw based on the count returned.
sub raw {
$substr = substr ($_, 3);
$raw1 = substr ($substr, 0, -4);
$raw = lc($raw1);
}
how to count from the c to the t inclusive so I get 3, 4, 5, etc ...

I have several users on handhelds and they like to let their sessions time out. Their zombie processes then cause record locks.I've come up with calls for killing the pids for any prior sessions started by a given user. This procedure would be executed in the .bash_profile.
