About losing your putty  often the ps       awk grep perl     process gets matched  too   So the old school trick is like this ps -ef   grep -i  n ohup   That way the regex search doesn t match the regex search process

Today I met the same problem  And since it was a long time ago  I totally forgot which command I used and when  I tried three methods    Using the STIME shown in ps -ef command  This shows the time you start your process  and it s very likely that you nohup you command just before you close ssh depends on you    Unfortunately I don t think the latest command is the command I run using nohup  so this doesn t work for me  Second is the PPID  also shown in ps -ef command  It means Parent Process ID  the ID of process that creates the process  The ppid is 1 in ubuntu for process that using nohup to run  Then you can use ps --ppid  1  to get the list  and check TIME the total CPU time your process use  or CMD to find the process s PID  Use lsof -i port if the process occupy some ports  and you will get the command  Then just like the answer above  use ps -ef   grep command and you will get the PID    Once you find the PID of the process  then can use kill pid to terminal the process

If you are unaware of the PID  then first find it using TOP command top -U userid PID USER      PR  NI  VIRT  RES  SHR S  CPU  MEM    TIME   COMMAND  You will get the PID using top  then perform the kill operation    kill -9  lt PID gt

Suppose you are executing a java program with nohup you can get java process id by  ps aux   grep java   output xxxxx     9643  0 0  0 0  14232   968 pts 2     then you can kill the process by typing sudo kill 9643  or lets say that you need to kill all the java processes then just use sudo killall java  this command kills all the java processes  you can use this with process  just give the process name at the end of the command sudo killall  processName

I am using red hat linux on a VPS server  and via SSH - putty   for me the following worked   First  you list all the running processes   ps -ef   Then in the first column you find your user name  I found it the following three times    One was the SSH connection The second was an FTP connection The last one was the nohup process   Then in the second column you can find the PID of the nohup process and you only type   kill PID     replacing the PID with the nohup process s PID of course   And that is it   I hope this answer will be useful for someone I m also very new to bash and SSH  but found 95  of the knowledge I need here

This works in Ubuntu  Type this to find out the PID  ps aux   grep java   All the running process regarding to java will be shown  In my case is   johnjoe      3315  9 1  4 0 1465240 335728        Sl   09 42   3 19 java -jar batch jar   Now kill it kill -9 3315  The zombie process finally stopped

I often do this way  Try this way   ps aux   grep script Name  Here  script Name could be any script file run by nohup  This command gets you a process ID  Then use this command below to kill the script running on nohup  kill -9 1787 787  Here  1787 and 787 are Process ID as mentioned in the question as an example  This should do what was intended in the question

When using nohup and you put the task in the background  the background operator   amp   will give you the PID at the command prompt  If your plan is to manually manage the process  you can save that PID and use it later to kill the process if needed  via kill PID or kill -9 PID  if you need to force kill   Alternatively  you can find the PID later on by ps -ef   grep  quot command name quot  and locate the PID from there  Note that nohup keyword command itself does not appear in the ps output for the command in question  If you use a script  you could do something like this in the script  nohup my command  gt  my log 2 gt  amp 1  amp  echo     gt  save pid txt  This will run my command saving all output into my log  in a script     represents the PID of the last process executed   The 2 is the file descriptor for standard error  stderr  and 2 gt  amp 1 tells the shell to route standard error output to the standard output  file descriptor 1   It requires  amp 1 so that the shell knows it s a file descriptor in that context instead of just a file named 1  The 2 gt  amp 1 is needed to capture any error messages that normally are written to standard error into our my log file  which is coming from standard output   See I O Redirection for more details on handling I O redirection with the shell  If the command sends output on a regular basis  you can check the output occasionally with tail my log  or if you want to follow it  quot live quot  you can use tail -f my log  Finally  if you need to kill the process  you can do it via  kill -9  cat save pid txt  rm save pid txt
