Top Forums Shell Programming and Scripting Looping through filenames with spaces Post 302274537 by KenJackson on Wednesday 7th of January 2009 10:45:49 PM

I made some progress with input from this forum, thank you, but I'm down to one stick point. Consider this simpler script:
Code:
#!/bin/sh
VAR=
echo 'A A
B B
C C' | while read f; do
    VAR="$VAR:$f"
    echo $f
done
echo "VAR=${VAR}"

The output is
Code:
A A
B B
C C
VAR=

The f variable echos properly in the loop, but I just can't seem to assign it's value to any other variable.
Why not?

lltag_formats(5)						File Formats Manual						  lltag_formats(5)

NAME

       formats - Internal formats database file for lltag

DESCRIPTION

       The  internal format database is usually stored in /etc/lltag/formats.  The user may override this file by defining a $HOME/.lltag/formats.
       If this file exists, the system-wide one is ignored.

       These files contain entries starting with a line such as:

       [%n - %a - %t]
	      A title between bracket that will be displayed at runtime.

       Then, the following 3 lines must be given to explain how the format is actually used to parse filenames:

       type = basename
	      The type is either basename (to parse the last part of the path to a file) or path (to parse the directory part of  the  path  to  a
	      file).   When actually parsing the path to target files, basename and path parsers will be assembled.  All possible combination will
	      be tried.

       regexp = %L%N%S-%S%A%S-%S%A%L
	      A string composed of any characters, with the following special fields:

	      %L for delimiter (empty by default, multiple spaces if --spaces was given)

	      %S for a space (or multiple spaces if --spaces was given)

	      %N for numbers

	      %A for an alphanumeric string without /

	      %P for any path (alphanumeric string with /)

	      %% for %

       indices = NUMBER,ARTIST,TITLE
	      A list of fields to match (either given by their full name or associated letter) corresponding to each %N or %A field in the  previ-
	      ous  format.   It  may be AUTHOR (or a), ALBUM (A), GENRE (g), NUMBER (n), TITLE (t), DATE (d), COMMENT (c) or IGNORE (i).  See also
	      FORMAT in the manpage of lltag for details about these fields.
