which check

[jzacman]

Hi, I have installed yacy in my system but when I tried to run the startYacy.sh file It always returned a message saying that my Java installation was not in PATH. After reinstalling my Java and made sure it was in PATH I studied the .sh file itself and I noticed that it was using the command which. To my surprise I didn't have which installed and that was the hole issue. Once I installed it all worked fine. So my Request is to add a check to the executable to verify if which is installed.

Please.
Salutations.

Hi, thanks for feedback! Which... eh... what system did you use? ;-)

[okybaca]

maybe `which` command could be replaced (or boosted) with UNIX standard `type` or rather `command -v`, as suggested here: https://unix.stackexchange.com/questions/126134/is-there-an-alternative-to-the-which-command https://pubs.opengroup.org/onlinepubs/9699919799/utilities/command.html# could you confirm, that `command -v java` gives a proper java executable on your platform?

[jzacman]

Thank you pretty much

$command -v java
/data/data/com.termux/files/usr/bin/java

commnad outputs the same as which
I am installing yacy server in my android phone via termux terminal emulator. Is quite an enjoyable thing.

nice, that could be the solution! unfortunately, `command` command doesn't work on debian, so it will be rather some ifs than just replacement. but android is worth of that.

try this fix:

does that work for you?

would you write just a few lines mini-howto on how you did get it run on android? so we could put it as an instruction in the documentation...
it's pretty cool to have yacy working on android!

[jzacman]

Sure thing okubaca

First download and install termux app in your android device from this link (choose your proper processor architecture)

https://github.com/termux/termux-app/releases

Second open the app and update the repositories and install the latest Java and requirements with this command:

pkg update && pkg upgrade && pkg install openjdk-21 git ant which -y

Then clone the repository and build the application:

git clone --depth 1 https://github.com/yacy/yacy_search_server.git
cd yacy_search_server
ant clean all

To start YaCy, run
./startYACY.sh
Upon starting yacy, the browser must launch the search page automatically. Remember to allow termux to Acquire wakelock by clicking on the notification so it doesn't pause. And for a better experience, open the appropiate port on your router's portforward page.

Stop YaCy on the console with
./stopYACY.sh

Here it is a quick guide. I hope is cool. Have an awesome day.

oh, great, thanks, that's comprehensive! i'm sure, it will help other android/people!

[jzacman]

no problem
