Couple minor tweaks to your code

[my file names does have eleven lines]

> cat comp_val
#! /bin/bash


n=$(ls -l | wc -l $file1)
echo "Line: "$n". ">>$LOGFILE

xx=$(sed -n "$=" $file1)
echo "Line: "$xx". ">>$LOGFILE

> rm *.log
> comp_val
> cat *.log
Line: 11 names.
Line: 11.

Tk you but still error...

Thenk's a lot for the response, but it still give me a:

...../ syntax error at line 167: `n=$' unexpected

it looks like it doesn't like:
n=$(ls -| | wc -l $file)

any other suggestions, also because after I need to do some arithmethic operations with n, like:

tk's again

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

$ cat ./comp_val

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

$ ./comp_val
In names.tmp: Line: 8.
In names: Line: 8.
