Top Forums UNIX for Dummies Questions & Answers Using "find" and "-exec rm" ... Just no luck :( Post 302349525 by methyl on Tuesday 1st of September 2009 07:17:08 AM

Hi jlliarge. I cited Sunos 4.1.1 based on a comment I made in an old script, though I no longer have a copy of the O/S. This is not the only time I have come across the problem.

The wikipedia section on "find" mentions "In some shells, the {} must be quoted". I can't argue with that.

find - Wikipedia, the free encyclopedia


The wiki looks pretty accurate bar not mentioning differences between "/pathname" and "/pathname/" in some unixes.


In this comprehensive GNU-based generic man page for find(1) it specifically states to quote '{}' . It also warns about security hole in the POSIX implementation of "find ... -exec" which I did not know about.

http://unixhelp.ed.ac.uk/CGI/man-cgi?find

This independent researcher has gone to town on checking what works in various versions of find. See under "Embedded {}". He describes some quite radical different behaviours of {} which does support my case.

template::plugin::url

Template::Plugin::URL(3)				User Contributed Perl Documentation				  Template::Plugin::URL(3)

NAME

       Template::Plugin::URL - Plugin to construct complex URLs

SYNOPSIS

	   [% USE url('/cgi-bin/foo.pl') %]

	   [% url(debug = 1, id = 123) %]
	      # ==> /cgi/bin/foo.pl?debug=1&id=123

	   [% USE mycgi = url('/cgi-bin/bar.pl', mode='browse', debug=1) %]

	   [% mycgi %]
	      # ==> /cgi/bin/bar.pl?mode=browse&debug=1

	   [% mycgi(mode='submit') %]
	      # ==> /cgi/bin/bar.pl?mode=submit&debug=1

	   [% mycgi(debug='d2 p0', id='D4-2k[4]') %]
	      # ==> /cgi-bin/bar.pl?mode=browse&debug=d2%20p0&id=D4-2k%5B4%5D

DESCRIPTION

       The "URL" plugin can be used to construct complex URLs from a base stem and a hash array of additional query parameters.

       The constructor should be passed a base URL and optionally, a hash array reference of default parameters and values.  Used from with a
       template, it would look something like the following:

	   [% USE url('http://www.somewhere.com/cgi-bin/foo.pl') %]
	   [% USE url('/cgi-bin/bar.pl', mode='browse') %]
	   [% USE url('/cgi-bin/baz.pl', mode='browse', debug=1) %]

       When the plugin is then called without any arguments, the default base and parameters are returned as a formatted query string.

	   [% url %]

       For the above three examples, these will produce the following outputs:

	   http://www.somewhere.com/cgi-bin/foo.pl
	   /cgi-bin/bar.pl?mode=browse
	   /cgi-bin/baz.pl?mode=browse&debug=1

       Note that additional parameters are separated by '"&"' rather than simply '"&"'.  This is the correct behaviour for HTML pages but is,
       unfortunately, incorrect when creating URLs that do not need to be encoded safely for HTML.  This is likely to be corrected in a future
       version of the plugin (most probably with TT3).	In the mean time, you can set $Template::Plugin::URL::JOINT to "&" to get the correct
       behaviour.

       Additional parameters may be also be specified to the URL:

	   [% url(mode='submit', id='wiz') %]

       Which, for the same three examples, produces:

	   http://www.somewhere.com/cgi-bin/foo.pl?mode=submit&id=wiz
	   /cgi-bin/bar.pl?mode=browse&id=wiz
	   /cgi-bin/baz.pl?mode=browse&debug=1&id=wiz

       A new base URL may also be specified as the first option:

	   [% url('/cgi-bin/waz.pl', test=1) %]

       producing

	   /cgi-bin/waz.pl?test=1
	   /cgi-bin/waz.pl?mode=browse&test=1
	   /cgi-bin/waz.pl?mode=browse&debug=1&test=1

       The ordering of the parameters is non-deterministic due to fact that Perl's hashes themselves are unordered.  This isn't a problem as the
       ordering of CGI parameters is insignificant (to the best of my knowledge).  All values will be properly escaped thanks to some code
       borrowed from Lincoln Stein's "CGI" module.  e.g.

	   [% USE url('/cgi-bin/woz.pl') %]
	   [% url(name="Elrich von Benjy d'Weiro") %]

       Here the spaces and ""'"" character are escaped in the output:

	   /cgi-bin/woz.pl?name=Elrich%20von%20Benjy%20d%27Weiro

       An alternate name may be provided for the plugin at construction time as per regular Template Toolkit syntax.

	   [% USE mycgi = url('cgi-bin/min.pl') %]
	   [% mycgi(debug=1) %]
