Strange question. Are you looking for a simple character search or actual dependence list of what .dll's your .exe calls. I was not aware that .exes run on unix and call .dlls. Of couse a windows system can access a unix drive share and load .exes from it. Pls clarify– kingchrisDec 3, 2009 at 4:28

Give this a try (assuming that it's a text file):
grep -o '.dll' filename | wc -l
If it's a binary file, try:
grep -binary-files=text -o '.dll' filename | wc -l
Or
strings filename | grep -o '.dll' | wc -l

You can do grep -c .dll <file>grep -o <file> | wc -l just change '.dll' to whatever you feel like searching for.
Use this:
perl -lne '$c++while/[.]dll/g;END{print$c}' <filename
You can modify the regular expression (/[.]dll/) in the middle to search for something else (see man perlre for details). If you want to search for something containing a newline, add -0777 after perl.
