getopt and getopts are different beasts, and people seem to have a bit of misunderstanding of what they do. getopts is a built-in command to bash to process command-line options in a loop and assign each found option and value in turn to built-in variables, so you can further process them. getopt, however, is an … Read more
Python tutorial explains it: import sys print(sys.argv) More specifically, if you run python example.py one two three: >>> import sys >>> print(sys.argv) [‘example.py’, ‘one’, ‘two’, ‘three’]
You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver Then you handle them in a param section (note that this must begin at the first non-commented line in your script). You can also assign default values to your params, read them from console if not available or … Read more
You can run gdb with –args parameter: gdb –args executablename arg1 arg2 arg3 If you are doing this often (e.g. when running GDB from a script), you might want to consider the following arguments to automate things further. First, you can place your GDB commands (such as ‘run’) in a text file and provide the … Read more
To read user input you can try the cmd module for easily creating a mini-command line interpreter (with help texts and autocompletion) and raw_input (input for Python 3+) for reading a line of text from the user. text = raw_input(“prompt”) # Python 2 text = input(“prompt”) # Python 3 Command line inputs are in sys.argv. … Read more
argv and argc are how command line arguments are passed to main() in C and C++. argc will be the number of strings pointed to by argv. This will (in practice) be 1 plus the number of arguments, as virtually all implementations will prepend the name of the program to the array. The variables are … Read more
Check these out: http://commons.apache.org/cli/ http://www.martiansoftware.com/jsap/ Or roll your own: http://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html For instance, this is how you use commons-cli to parse 2 string arguments: import org.apache.commons.cli.*; public class Main { public static void main(String[] args) throws Exception { Options options = new Options(); Option input = new Option(“i”, “input”, true, “input file path”); input.setRequired(true); options.addOption(input); Option … Read more
I would strongly suggest using NDesk.Options (Documentation) and/or Mono.Options (same API, different namespace). An example from the documentation: bool show_help = false; List<string> names = new List<string> (); int repeat = 1; var p = new OptionSet () { { “n|name=”, “the {NAME} of someone to greet.”, v => names.Add (v) }, { “r|repeat=”, “the … Read more
import sys print(“\n”.join(sys.argv)) sys.argv is a list that contains all the arguments passed to the script on the command line. sys.argv[0] is the script name. Basically, import sys print(sys.argv[1:])
The reason this occurs is because bash actually expands the asterisk to every matching file, producing a very long command line. Try this: find . -name “*.pdf” -print0 | xargs -0 rm Warning: this is a recursive search and will find (and delete) files in subdirectories as well. Tack on -f to the rm command … Read more
