How about using
stat -c '%s'
to get the file size in a single command, without need to actually read all the data?
because `stat` isnt portable :(. it isnt part of the POSIX standard ... OS X certainly does not support this, and i imagine most *BSD's dont.
`wc -c` on the other hand should work everywhere and is part of POSIX. looking at the `strace` output, the GNU wc doesnt actually read() the file when using just the -c option. seems to use lseek(SEEK_END). -mike
