@franklin,

the $list needs to be double quoted right ?

Code:
 
$ list=`ls *.mk`
 
$ echo $list | wc -l
       1
 
$ echo "$list" | wc -l
       2
 
$ ls *.mk
abc.mk  efg.mk
 
$ echo "$list"
abc.mk
efg.mk
 
$ echo $list
abc.mk efg.mk

Just to ensure that files are listed one per line
Code:
ls -1 xyz* | wc -l

Note that the ls command return a display that is ascii sorted by default

In some case, when you have numerous files, you may want to skip that sorting operation (in order to speed up processing) and diplay files as soon as they are encountered in the directory structure (use the -f option of ls)

Code:
ls -f | wc -l
