Top Forums UNIX for Dummies Questions & Answers Using "find" and "-exec rm" ... Just no luck :( Post 302348792 by methyl on Saturday 29th of August 2009 06:36:26 PM

Similar background, but I may have 10 years head start largely due to time spent on VME and VMS.

Omg! Minix (nostalgic moment).
Remember OS/9 (not the MAC one)?

Notwithstanding our combined experience we will both have seen anomalous behaviour in Operating Systems.

I cannot believe that I am the only person to have encountered problems with unix commands dealing with space characters in filenames.
The question still remains: Why have I seen the "{}" problem before?

I am exploring Reborg's ideas which imply that some older shells were eating the {}. If proven, this would explain it. I don't have access to the source code to the various editions of "find" - unlike when I was working on enhancements to RSX.


Sorry Reborg, my example was pedantic and addressed to those who quote the POSIX definition of the expected behaviour of a command rather than to those of us who know how the command behaves in a shell enviroment if we use that command correctly.

As we all know from the roots of unix, if all else fails and the command does not do what you want - write your own.



Btw. jlliagre is cool and I am enjoying this debate.

NAME

       page_util_quote - page character quoting utilities

SYNOPSIS

       package require page::util::quote  ?0.1?

       package require snit

       ::page::util::quote::unquote char

       ::page::util::quote::quote'tcl char

       ::page::util::quote::quote'tclstr char

       ::page::util::quote::quote'tclcom char

_________________________________________________________________

DESCRIPTION

       This package provides a few utility commands to convert characters into various forms.

API

       ::page::util::quote::unquote char
	      A  character,  as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
	      their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the  result
	      of the command.

       ::page::util::quote::quote'tcl char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
	      regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.

       ::page::util::quote::quote'tclstr char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl  parser  and
	      will generate a human readable representation of the character in question.  The string is returned as the result of this command.

	      The  string  does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
	      with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.

       ::page::util::quote::quote'tclcom char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser  when
	      used within a Tcl comment. The string is returned as the result of this command.
