first open terminal using Ctrl+alt+T and paste command using Ctrl+Shift+V. OR you can type in terminal.
/usr/bin/tickr -instance-id=1 -win_y=200 & /usr/bin/tickr -instance-id=2 -win_y=250
this is actually two commands
/usr/bin/tickr -instance-id=1 -win_y=200 and
/usr/bin/tickr -instance-id=2 -win_y=250
lets interpret this
/usr/bin/tickr is path+executable file to make it more clear
/usr/bin/ is path (means reference where is the file) and
tickr is executable file.
tickr executable file.
/usr/bin/tickr to execute it always uses default parameters. Parameters are used to run executable with changed default parameters. So parameters are used to change behaviour.
there is many parameter on site you provided with different uses of it.
here first parameter is
-instance-id=1 Used when launching several instances simultaneously, each instance using its own config and dump files (to be effective, instance-id must be the 1st argument). Which states
id is 1.
now second parameter
-win_y=200 which is used to give Window position - y
instances will be closed if you close terminal to prevent this prefix
nohup to command. so it will become
nohup /usr/bin/tickr -instance-id=1 -win_y=200 & /usr/bin/tickr -instance-id=2 -win_y=250
you can use any number of parameters.
hope this helps.
