Let's suppose I have 5 bash (.sh) scripts in a folder (my_folder) and they are named as follows:

script_1.sh
script_2.sh
script_3.sh
script_4.sh
script_5.sh

How can I write a sixth bash script or just a one liner that will start running all these scripts together?

I need the 5 scripts to start running all together at the same time and not one after the other.

Any suggestion?
Thanks

To run all scripts at the same time (in parallel) use:

script_1.sh &
script_2.sh &
script_3.sh &
script_4.sh &
script_5.sh &

To run the one after the other (sequentially) use:

script_1.sh &&
script_2.sh &&
script_3.sh &&
script_4.sh &&
script_5.sh

Enhancement for comments

If you have 200 scripts you want to run at the same time (which might bog down the machine BTW) use this script:

#!/bin/bash
for Script in my_folder/*.sh ; do
 echo "$Script" &
done

Set the script attributes to executable with the command:

chmod a+x /path/to/script.sh

The first time you run the script it will only echo the names of the 200 scripts it will be executing. When you are happy the right names are being selected edit the script and change this line:

 echo "$Script" &

to:

 "$Script" &

  @aaaaa Do you actually prefer that all 200+ scripts to run at the same time, or would you rather have some smaller number (say, 10) run at a time, with the others queued to run when one or more of them finishes and the number of currently running scripts drops below that number? (If you're interested in such solutions, I suggest editing your question with information about how many scripts you have, how long they tend to take to run, what kind of work they do, and so forth.)

There's a tool for this, read man run-parts.

For example, I do:

 run-parts $visorhome/pbackup.d/

in my Palm Pilot backup script. $visorhome/pbackup.d/:

  Good point. I do think you may still want to mention that run-parts executes the scripts sequentially rather than all at once as the OP requested. You're right, though, that running 200 scripts at once is unlikely to perform the same as running 5--and even if running them all at once doesn't cause any problems, it may still be unnecessary. I've commented to suggest the OP clarify their preferences in this regard.
