Runnings several commands

[DrTeeth]

When running several commands, is it possible to run them together like in a batch file or must they be run one after another?

Using SSH client (Xshell 4) to connect to my N66U running Merlin's 374.42

Thanks

I'm not sure what you mean by "like a batch file" because batch files, like scripts, execute commands sequentially. But if you've got a command that takes a long time to run and you don't want to wait for it to finish (and return the command prompt) you can run it in background.

To run a command in background just put an ampersand at the end.

# sleep 5 &

Or do you actually want to create a shell script (like a DOS batch file)? https://github.com/RMerl/asuswrt-merlin/wiki/User-scripts#creating-scripts

Depends what you want to do.

If you want to run three commands with no direct relation to one another, separate them with semi-columns:

mkdir /tmp/test ; cp /mnt/sda1/myfile /tmp/test ; ls /tmp/test

If you want to run the second command only if the first one succeeded, use &&. For example, this is how I upgrade my router when flashing a test build:

mtd-write2 /tmp/l.trx linux && reboot

If the first command fails, the reboot won't occur. That gives me a chance to re-flash a proper FW.

And there are the piping capabilities of Linux, where the output of one command can be provided to another command. For example, this will display your nvram, sorted in alphabetical order, pausing between every pages:

nvram show | sort | more

I was thinking of the commands used for changing locales. Rather then running each line one at a time, I could paste the whole lot to run. Sounds like your first example would do what I want.

Thanks.
