Top Forums Shell Programming and Scripting Can a string be a command line argument? Post 302606481 by gull04 on Sunday 11th of March 2012 05:06:29 PM

Hi thibodc,

Not so hard, the format would be as follows;

Code:
./scriptname string

If the string has spaces in it then it would have to be enclosed in quotes like this.

Code:
./scriptname "this is a string"

To use in the script you would reference $1 the first command line argument after the scriptname.

As an example;

Code:
echo $1

Hope that this helps.

Regards

Dave

NAME
specrb - standalone test runner for test/spec and Test::Unit test suites SYNOPSIS
specrb [OPTIONS] [FILES | -a ] [-- untouched arguments] DESCRIPTION
The Ruby script specrb allows you to run tests written with test/spec from the command line. It can also be used for plain Test::Unit test suites. You can either specify the names of the test files you want to run, or let specrb find automatically all the tests in your project, by using the -a switch (see TEST/SPEC OPTIONS below). You can also use various options on the command line to pass parameters to the Ruby interpreterm or to modify the behavior of test/spec and/or test/unit. RUBY OPTIONS
-e, --eval LINE evaluate a LINE of code -d, --debug set debugging flags (set $DEBUG to true) -w, --warn turn warnings on for your script -I, --include PATH specify $LOAD_PATH (may be used more than once) -r, --require LIBRARY require the LIBRARY, before executing your script TEST
/SPEC OPTIONS: -s, --specdox do AgileDox-like output --rdox do AgileDox-like output with RDoc formatting -a, --automatic gather tests from ./test/, include ./lib/ TEST
::UNIT OPTIONS: -n, --name NAME runs tests matching regexp NAME -t, --testcase TESTCASE runs tests in TestCases matching regexp TESTCASE COMMON OPTIONS
: -h, --help show a message similar to this manpage --version show version AUTHORS
The test/spec library has been written by Christian Neukirchen <http://purl.org/net/chneukirchen>. This manual page, inspired by the help message of specrb, has been written for the Debian Project by Cedric Boutillier (but may used by others). 2012-06-26 SPECRB(1)
