Let's briefly discuss how to deal with a resources folder and directories in Scala project. Here's how to list the files that start with "03_ss": os.list (os.pwd/"local_data").filter (_.segments.toList.last.startsWith ("03_ssa")) This solution is powerful because it lets you perform additional filesystem operations on the files that start with "03_ssa".

This is activated by the -l option, which means a long listing format as in the next screenshot: . bgRun Start an application's default main class as a background job bgRunMain Start a provided main class as a background job clean Deletes files produced by the build, such as generated sources, compiled classes, and task caches. For instance, this method creates a list of all files in a directory: You can match a pattern that includes groups. You can as well print detailed information about each file in the ls output, such as the file permissions, number of links, owner's name and group owner, file size, time of last modification and the file/directory name.. First, lists are immutable, which means elements of a list cannot be changed by assignment. For example, to apply the ECHO command to every DLL file in C:\Windows\System32: main () method accepts an array of strings. Then it is hard to manually count number of files within a directory in Linux system using command line.
