So if the input file is considered as space separated, do you want each message sent to a file based on column 8 (they are all 404 in your example)

You could use less processing with:-
Code:
#!/bin/ksh
while read a b c d e f g h rest
do
   echo "$a $b $c $d $e $f $g $h $rest" >> /path/to/file-$h
done < logfile

If you want to base it on the first bit of column 7 (the pl, uk or common bit) you need another tweak to split up to column:-
Code:
#!/bin/ksh
while read a b c d e f g h rest
do
   ref="${g#/}"          # Trim off leading /
   ref="${ref%%/*}"      # Trim off everything after the first /
   echo "$a $b $c $d $e $f $g $h $rest" >> /path/to/file-$ref
done < logfile

Of course, you could use both if you with, so your output file will become /path/to/file-$ref-$h or whatever.

If you have codes in column 8 that are errors for one file and others for just loggings, you could:-
Code:
#!/bin/ksh
while read a b c d e f g h rest
do
   case $h in
      2??|3??) type=valid ;;
      4??|5??) type=error ;;
      *)       type=other ;;
   esac   
   echo "$a $b $c $d $e $f $g $h $rest" >> /path/to/file-$type
done < logfile

.... or again some combination with other suggestions to build your output name.


I'm not sure I've understood the question, but these are a few options for what I think you are after.

If I've got it wrong, can you post some input and the expected out with the relevant file names you want to generate and I will have another go.

git-symbolic-ref

GIT-SYMBOLIC-REF(1)						    Git Manual						       GIT-SYMBOLIC-REF(1)

NAME

       git-symbolic-ref - Read, modify and delete symbolic refs

SYNOPSIS

       git symbolic-ref [-m <reason>] <name> <ref>
       git symbolic-ref [-q] [--short] <name>
       git symbolic-ref --delete [-q] <name>

DESCRIPTION

       Given one argument, reads which branch head the given symbolic ref refers to and outputs its path, relative to the .git/ directory.
       Typically you would give HEAD as the <name> argument to see which branch your working tree is on.

       Given two arguments, creates or updates a symbolic ref <name> to point at the given branch <ref>.

       Given --delete and an additional argument, deletes the given symbolic ref.

       A symbolic ref is a regular file that stores a string that begins with ref: refs/. For example, your .git/HEAD is a regular file whose
       contents is ref: refs/heads/master.

OPTIONS

       -d, --delete
	   Delete the symbolic ref <name>.

       -q, --quiet
	   Do not issue an error message if the <name> is not a symbolic ref but a detached HEAD; instead exit with non-zero status silently.

       --short
	   When showing the value of <name> as a symbolic ref, try to shorten the value, e.g. from refs/heads/master to master.

       -m
	   Update the reflog for <name> with <reason>. This is valid only when creating or updating a symbolic ref.

NOTES

       In the past, .git/HEAD was a symbolic link pointing at refs/heads/master. When we wanted to switch to another branch, we did ln -sf
       refs/heads/newbranch .git/HEAD, and when we wanted to find out which branch we are on, we did readlink .git/HEAD. But symbolic links are
       not entirely portable, so they are now deprecated and symbolic refs (as described above) are used by default.

       git symbolic-ref will exit with status 0 if the contents of the symbolic ref were printed correctly, with status 1 if the requested name is
       not a symbolic ref, or 128 if another error occurs.
