That is because you are using sh and trying to use bash specific constructs. This should work with sh:

Code:
$ cat ./comp_val
#!/bin/sh

file1=names
file2=${file1}.tmp
LOGFILE=test.log
cp $file1 $file2

n=`ls -l | wc -l $file1 |awk '{print $1}'`
echo "In $file2: Line: ${n}." > $LOGFILE

xx=`sed -n '$=' $file2`
echo "In $file1: Line: ${xx}. ">> $LOGFILE

echo "$n-2="`expr ${n} - 2` >> $LOGFILE

cat $LOGFILE
$
$
$ ./comp_val
In names.tmp: Line: 8.
In names: Line: 8.
8-2=6

xzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
