Linux Script

[Gomo]

Hello guys,

 

does anyone know how to create a script which would do the following: "fail2ban-client set web-manual-jail banip {x}.{x}.{x}.{x}"

I have a decent list of IPs that need to be added to that jail (web-manual-jail) and was wondering if something like this could be made? So that for example I only need to run "mb x.x.x.x" (mb - "manual ban").

 

Your help would be appreciated!

Thanks!

you can literally just type that in a .sh file and voila, there's your script.

Clearly I am a bit clueless on how to do that.. would the parameter / placeholder part work?

OH, I misunderstood. I thought the "x.x.x.x" part was just an example placeholder. In that case it's still quite simple, you can use $1 to refer to the first argument given to the script when you run it.

so basically you'd have

fail2ban-client set web-manual-jail banip $1

So you want to shorten  "fail2ban-client set web-manual-jail banip x.x.x.x"  to just mb x.x.x.x

 

Easiest way is to use an alias in your .bashrc file

alias mb='fail2ban-client set web-manual-jail banip'

Now you can just use mb x.x.x.x

Thanks! that's pretty much what I was looking for

 

@SauronThanks as well!
