If it is your one and only background job you can kill it with kill %1. If not sure you can list all your background jobs with jobs and use kill %<n> where you replace n by the number of your ping job.

  I used kill in the same terminal too (though the output made it difficult to use). However, I was wondering what to do if I couldn't go far back up in the terminal to see the process id printed, so pgrep has helped, additionally.

  When you use pgrep to search processes by name, you can also use pkill to kill them by name. No need to type/copy the process id and use kill.

When you send a process to the background, whether by using ctrl-z or by & at the end of the command, you get an output in the following format: [index] process-id. If you send multiple processes to the background, the index will keep incrementing every time.

For example:

$ sleep 100 &
[1] 41608
$ sleep 101 &
[2] 41609
$ sleep 102 &
[3] 41610
$ sleep 103 &
[4] 41611
$ sleep 104 &
[5] 41612
$ sleep 105 &
[6] 41613
$ sleep 106 &
[7] 41614

In order to stop a specific one, you can either use kill <process-id> or use fg <index> followed by ctrl-c

Example using the previous output:

$ kill 41614

or

$ fg 7
sleep 106
^C

When you send a process to the background, whether by using ctrl-z or by & at the end of the command, you get an output in the following format: [index] process-id. If you send multiple processes to the background, the index will keep incrementing every time.

For example:

$ sleep 100 &
[1] 41608
$ sleep 101 &
[2] 41609
$ sleep 102 &
[3] 41610
$ sleep 103 &
[4] 41611
$ sleep 104 &
[5] 41612
$ sleep 105 &
[6] 41613
$ sleep 106 &
[7] 41614

In order to stop a specific one, you can either use kill <process-id> or use fg <index> followed by ctrl-c

Example using the previous output:

$ kill 41614

or

$ fg 7
sleep 106
