The problem with your code is that the shell uses whitespace to delimit words.
Suppose you have a file named "two words", and you write a command like "cp two words" - how is the shell supposed to know wether you want the file "two" copied to "words" or if you are talking about the file "two words" and the second argument is missing?
The same is true for the for-loop, which passes one argument at a time to the content of the loop - and "one argument" is "one word", because this is where the stream the for-loop works on was split at.
So, here is a script which relies on exactly this mechanism:
Code:
#!/usr/bin/ksh
typeset oldfile=""
typeset newfile=""
# the grep filters for filenames with spaces only:
ls -1 | grep "[^ ] [^ ]" | while read oldfile ; do
newfile="$( print - $oldfile | tr -d ' ')"
print - "mv \"${oldfile}\" \"${newfile}\"" # just display, next line is working
# mv "$oldfile" "$newfile"
done
By the way: do not use for-loops to process lists of unknown length, like a directory listing. If the list grows too long it will exceed your maximum line length (see syslimits.h) and your code will break. Using a while-loop removes this risk.

I got one simple TXT file with long file name with blank spaces in between the words. I am trying to display that full file name, but it breaks while displaying. Could somebody shed some light here?

Hi All,

Courier::Filter::Module::Header(3pm) User Contributed Perl Documentation Courier::Filter::Module::Header(3pm)NAME
Courier::Filter::Module::Header - Message header filter module for the Courier::Filter framework
SYNOPSIS
use Courier::Filter::Module::Header;
my $module = Courier::Filter::Module::Header->new(
fields => \%patterns_by_field_name,
response => $response_text,
logger => $logger,
inverse => 0,
trusting => 0,
testing => 0,
debugging => 0
);
my $filter = Courier::Filter->new(
...
modules => [ $module ],
...
);
DESCRIPTION
This class is a filter module class for use with Courier::Filter. It matches a message if one of the message's header fields matches the
configured criteria.
Constructor
The following constructor is provided:
new(%options): returns Courier::Filter::Module::Header
Creates a new Header filter module.
%options is a list of key/value pairs representing any of the following options:
fields
Required. A reference to a hash containing the message header field names and patterns (as key/value pairs) that messages are to
be matched against. Field names are matched case-insensitively. Patterns may either be simple strings (for exact, case-sensitive
matches) or regular expression objects created by the "qr//" operator (for inexact, partial matches).
So for instance, to match any message from the "debian-devel" mailing list with the subject containing something about 'duelling
banjoes', you could set the "fields" option as follows:
fields => {
'list-id' => '<debian-devel.lists.debian.org>',
subject => qr/duell?ings+banjoe?s?/i
}
response
A string that is to be returned literally as the match result in case of a match. Defaults to "Prohibited header value detected:
<field>: <value>".
All options of the Courier::Filter::Module constructor are also supported. Please see "new()" in Courier::Filter::Module for their
descriptions.
Instance methods
See "Instance methods" in Courier::Filter::Module for a description of the provided instance methods.
