Output Command-Line Arguments One by One (Unix Power Tools, 3rd Edition) 27.5. Output Command-Line Arguments One by One Go to http://examples.oreilly.com/upt3 for more information on: showargs When you're experimenting with shell quoting, it's nice to be able to see how arguments on a command line are quoted. Here's a demo of a simple bash script[83] named showargs; you might want to save it in a file and run it yourself (Section 35.1). The script shows how many arguments were passed to it. Then it lists the arguments, one per line, surrounded by >> << to show leading or trailing spaces. [83]The script uses bash because, as this article explains later, its built-in echo (Section 27.5) command has the -E option to prevent interpretation of special characters. cat Section 12.2, && Section 35.14, $# Section 35.20, path Section 35.7 % cat showargs #!/bin/bash test $# -ne 1 && s=s echo "I got $# argument$s:" for arg do echo -E ">>$arg<<" done % showargs "Start of path:" $path[1-3] " that's it! " I got 5 arguments: >>Start of path:<< >>/u/jpeek/bin<< >>/bin<< >>/usr/bin<< >> that's it! << The output from your shell may differ from that shown above, which is the result of running showargs in tcsh. bash doesn't have a $path variable, for example. And zsh expects a comma, rather than a hyphen, to separate the range. But as long as the arguments to showargs are quoted properly, you should get the result you're looking for, with a little tweaking, of course! --JP and SJC 27.4.
