-log <logfile>
This option allows you to change the file in which the program writes its journal of events, or so-called log file. By default the logfile is atomsk.log.
Note that if you use another log file name, then the level of verbosity will be automatically set to 3, unless you specify a verbosity level different from 0 and 1.
To make this change permanent, you may set up a configuration file.
By default the logfile is atomsk.log.
atomsk initial.gin cfg -log myrun.log
This will write the progress of the program both on screen and in the file myrun.log.
atomsk initial.gin cfg -log myrun.log -v 0
Same as before. Because you specified an alternate logfile, the level of verbosity cannot be 0 -it is reset to 3.
atomsk initial.gin cfg -log myrun.log -v 2
This will write the progress of the program only in the file myrun.log (nothing will be displayed on screen except error messages).
