You're right, but Unix filenames don't "normally" have spaces.

Time: 8 - 10 seconds (on some FS full of rubbish on my system):
Code:
find . -type f | xargs -I{} cat "{}" | wc -l

Time: 2 - 3 seconds (but doesn't handle some files):
Code:
find . -type f | xargs cat | wc -l

Ergo: awk rocks (and cat is cool) Smilie
Did you run each example more than once, or are the examples you posted exactly what you did test?

After the first run, depending on your filesystem and OS, there's a good chance that a lot of the data is going to be cached and not read from disk.

NAME
gzexe - compress executable files in place SYNOPSIS
gzexe [ name ... ] DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a penalty in performance). For example if you execute ``gzexe /bin/cat'' it will create the following two files: -r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat -r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~ /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file. You can remove /bin/cat~ once you are sure that /bin/cat works properly. This utility is most useful on systems with very small disks. OPTIONS
-d Decompress the given executables instead of compressing them. SEE ALSO
gzip(1), gznew(1), gzmore(1), gzcmp(1), gzforce(1) CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep). BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases, using chmod or chown. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWgzip | +--------------------+-----------------+ |Interface Stability | External | +--------------------+-----------------+ NOTES
Source for gzip is available in the SUNWgzipS package. GZEXE(1)
