In this article, we would like to show you how to work with multiple tasks in Bash.

Preview:

Simple steps:

1. run some command e.g. that blocks console:

xxxxxxxxxx

sleep 60

Hint: to run the command directly in the background add & at the end, e.g. sleep 60 &.

2. press Ctrl+Z to put command to the background (detaching)

Hint: now you can run more different commands and press Ctrl+Z

3. to display background jobs run the following command:

xxxxxxxxxx

jobs -l

Where -l is optional and means list.

Example output:

xxxxxxxxxx

[1]- 34835 Stopped                 sleep 60

[2]+ 34836 Stopped                 sleep 60

4. to stop the process use the following command:

xxxxxxxxxx

kill %process_number

e.g:

xxxxxxxxxx

kill %1

​

# or:

​

kill %2

5. to bring the process back to the terminal (attaching) run the following command:

xxxxxxxxxx

fg process_number

e.g:

xxxxxxxxxx

fg 1

​

# or:

​

fg 2
