You may use # for comments in script file. You can use multi line commands (start argument on new line) or enter all arguments in single line as below example. Multi-line command gives you better readability specially when you have long commands with lots of arguments. Feel free to use tabs or spaces or blank lines anywhere before or after any argument or command . Parser always trims line internally and ignore comments and blank lines.
DemoScriptFile.txt
#this is first command. Multi-line command
get myroot/somefile*.txt
--crfol
--overwite
#this is second command. Single-line command
put c:\storage\*.txt myroot/ --overwrite -c
Save above script to some file e.g. DemoScriptFile.txt
You may now execute above file using following command
context:>
