Trying to start HLTV with a script

[forrestparkay]

I am attempting to start an HLTV server with a script.

Normally, if I try to start HLTV, I have to launch screen, and then execute the command

export LD_LIBRARY_PATH=".:LD_LIBRARY_PATH"

I am trying to do that in a bash script.

If my script reads like this, it launches a screen instance, but of course fails to launch the HLTV server because of the known errors without exporting that library.

#!/bin/bash

screen -X -S aim quit
sleep 4
cd /home/gamer/hltv/cstrike/aim
/usr/bin/screen -dmS aim ./hltv +exec hltv_aim.cfg -port 27021

The minute I add the export, it no longer launches the screen.

#!/bin/bash

screen -X -S aim quit
sleep 4
cd /home/gamer/hltv/cstrike/aim
/usr/bin/screen -dmS aim export LD_LIBRARY_PATH=".:LD_LIBRARY_PATH" && ./hltv +exec hltv_aim.cfg -port 27021

Instead, it ignores the screen command, ignores the export command, and instead attempts to launch the hltv in the current window. (Which of course fails.)

Any ideas how to use a script to launch an HLTV?

First off, you don't have to launch screen with /usr/bin/screen. Just use "screen."

Secondly, screen is including the export in the -dmS parameter, which is invalid. That's why it's failing.

First off, I know it's not required, but there is no harm in being absolute.

Secondly you are wrong, I am using plenty of other bash scripts with the -dmS parameter (which starts a screen named "aim" in detached mode), and they work just fine.

Could be a precedence issue. The parser probably reads it as

( /usr/bin/screen -dmS aim export LD_LIBRARY_PATH=".:LD_LIBRARY_PATH" ) && ( ./hltv +exec hltv_aim.cfg -port 27021 )

when it should be

/usr/bin/screen -dmS aim ( export LD_LIBRARY_PATH=".:LD_LIBRARY_PATH" && ./hltv +exec hltv_aim.cfg -port 27021 )

Please take this symbolic, using actual parentheses may or may not work, as the contents are executed in a sub shell.

What I have done is creating an extra script that basically contains the export and the hltv commands, and added this script to the screen command line.

/usr/bin/screen -dmS aim ~/my_scripts/hltv_script.sh

Perhaps it would also work to add the export command prior to executing screen, but I have a feeling that it won't.

Btw, you forgot a '$'. It doesn't matter though because the hltv only needs the dot as path anyway.

export LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH"
