How run solr from command line?

Question

I run:

solr@server:~$ /usr/lib/jvm/java-8-oracle/bin/java -server -Xms512m -Xmx512m -XX:NewRatio=3 -XX:SurvivorRatio=4 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=8 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 -XX:+CMSScavengeBeforeRemark -XX:PretenureSizeThreshold=64m -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=50 -XX:CMSMaxAbortablePrecleanTime=6000 -XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled -verbose:gc -XX:+PrintHeapAtGC -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintTenuringDistribution -XX:+PrintGCApplicationStoppedTime -Xloggc:/var/solr/logs/solr_gc.log -Djetty.port=8983 -DSTOP.PORT=7983 -DSTOP.KEY=solrrocks -Duser.timezone=UTC -Djetty.home=/opt/solr/server -Dsolr.solr.home=/var/solr/data -Dsolr.install.dir=/opt/solr -Dlog4j.configuration=file:/var/solr/log4j.properties -Xss256k -XX:OnOutOfMemoryError=/opt/solr/bin/oom_solr.sh 8983 /var/solr/logs -jar /opt/solr-5.5.4/server/start.jar --module=http

And I get an error:

As suggested by @MatsLindh, use solr script.

In terminal navigate to /opt/solr.

cd /opt/solr

you can see solr.sh file inside bin folder and hit the below command

bin/solr start

For other options use help command

bin/solr -h
