The output you have posted makes no sense for the line you have pasted. wc -l would print a number.

It's possible that a tab or something has convinced awk that the first field is blank, rather than a space...

If you're using awk, there's no point using grep too. awk can check if something's blank by itself and thereby shrink your pipe chain.

Also see Useless Use of Cat.

Code:
sort -u < /tmp/mediacheck | awk '$1 { print $1 }'

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
