Just create a simple shell script

#!/bin/sh
./srcds_run -game csgo -console -usercon +game_type 0 +game_mode 1 +mapgroup mg_active +map de_dust2 -tickrate 128

Just put a simple shell script in the directory where your game resides

#!/bin/sh
cd $(dirname $0)
./srcds_run -game csgo -console -usercon +game_type 0 +game_mode 1 +mapgroup mg_active +map de_dust2 -tickrate 128

Should you want to put the script somewhere else, you should use the full path

#!/bin/sh
/path/to/srcds_run -game csgo -console -usercon +game_type 0 +game_mode 1 +mapgroup mg_active +map de_dust2 -tickrate 128
