Is the text below the commented command the contents of /tmp/mediacheck? I don't see any spaces on any line. There are no duplicate input lines in that file. Why do you need to sort it? If you just want a count of lines that aren't empty. This is much simpler than your current code:
If there are more fields in your input and you really meant that you only want to count lines that contain at least one <space> character, please give us a real example of what is in /tmp/mediacheck.
It sounds a bit confusing but what I have is a text file like the example below (without the Line1, Line2, Line3 etc. of course) and I want to move every group of characters into a new line after each space.
Example of text file;
line1 .digg-widget-theme2 ul { background: rgb(0, 0, 0) none... (7 Replies)

Hey guys,
I'm having a bit of trouble getting this to work using either sed or grep. It's possible awk might be the ticket I need as well, but my regulat expression skills aren't quite up to the task for doing this.

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If one of the file names is the
standard input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Input fields are normally separated spaces or tabs; output fields by space. In this case, multiple separators count as one, and leading
separators are discarded.
The following options are recognized, with POSIX syntax.
-a n In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-v n Like -a, omitting output for paired lines.
-e s Replace empty output fields by string s.
-1 m
-2 m Join on the mth field of file1 or file2.
-jn m Archaic equivalent for -n m.
-ofields
Each output line comprises the designated fields. The comma-separated field designators are either 0, meaning the join field, or
have the form n.m, where n is a file number and m is a field number. Archaic usage allows separate arguments for field designators.
-tc Use character c as the only separator (tab character) on input and output. Every appearance of c in a line is significant.
EXAMPLES
sort /adm/users | join -t: -a 1 -e "" - bdays
Add birthdays to password information, leaving unknown birthdays empty. The layout of is given in users(6); bdays contains sorted
lines like
tr : ' ' </adm/users | sort -k 3 3 >temp
join -1 3 -2 3 -o 1.1,2.1 temp temp | awk '$1 < $2'
Print all pairs of users with identical userids.
SOURCE
/sys/src/cmd/join.c
SEE ALSO sort(1), comm(1), awk(1)BUGS
With default field separation, the collating sequence is that of sort -b -ky,y; with -t, the sequence is that of sort -tx -ky,y.
One of the files must be randomly accessible.
