(g)awk how to preseve white spaces (FS characters) or read a right subpart of $0?
Hi,
I am using gawk (--posix) for extracting some information from something like the following lines (in a text file):
sms_snath_hp_C/CORE BUILD PREREQUISITE:
total 1556
drwxrwxrwx 2 sn sn 4096 2008-06-27 08:31 ./
drwxrwxrwx 13 sn sn 4096 2009-07-22 14:48 ../
-rwxrwxrwx 1 sn sn 15348 2007-05-11 08:37 This is a file name with seven spaces.jar*
-rwxrwxrwx 1 sn sn 22395 2007-05-11 08:37 This is a file name with eight spaces.jar*
-rwxrwxrwx 1 sn sn 73687 2007-05-11 08:37 ibmjcefw.jar*
-rwxrwxrwx 1 sn sn 767101 2007-05-11 08:37 ibmjceprovider.jar*
With regular expressions (pattern matching) I am ignoring all the lines except the ones which are NOT directories with long listing format.
So I consider only:
-rwxrwxrwx 1 sn sn 15348 2007-05-11 08:37 This is a file name with seven spaces.jar*
-rwxrwxrwx 1 sn sn 22395 2007-05-11 08:37 This is a file name with eighteen spaces.jar*
-rwxrwxrwx 1 sn sn 73687 2007-05-11 08:37 ibmjcefw.jar*
-rwxrwxrwx 1 sn sn 767101 2007-05-11 08:37 ibmjceprovider.jar*
Question is: How do I get the file names with preserving the white spaces in between?
Note that the file has no embedded FS character, then it is just $8 and the problem is over. If the file name has embedded multiple FS characters, then I just do not want to concatenate $8 FS $9 FS $10 (etc in a loop) but I also want to have the multiplicity of the FS characters preserved.
(something like that "read v1 v2 v3 v4 v5 v6 v7 fileName" would do).
Thanks.

MKDIR(1) BSD General Commands Manual MKDIR(1)
NAME
mkdir -- make directories
SYNOPSIS
mkdir [-p] [-m mode] directory_name ...
DESCRIPTION
mkdir creates the directories named as operands, in the order specified, using mode rwxrwxrwx (0777) as modified by the current umask(2).
The options are as follows:
-m Set the file permission bits of the final created directory to the specified mode. The mode argument can be in any of the formats
specified to the chmod(1) utility. If a symbolic mode is specified, the operation characters ``+'' and ``-'' are interpreted rela-
tive to an initial mode of ``a=rwx''.
-p Create intermediate directories as required. If this option is not specified, the full path prefix of each operand must already
exist. Intermediate directories are created with permission bits of rwxrwxrwx (0777) as modified by the current umask, plus write
and search permission for the owner. Do not consider it an error if the argument directory already exists.
The user must have write permission in the parent directory.
EXIT STATUS
mkdir exits 0 if successful, and >0 if an error occurred.
SEE ALSO
chmod(1), rmdir(1), mkdir(2), umask(2)
STANDARDS
The mkdir utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
