I am looking for a way to test if a file is empty or not in a script. I see access to see if a file exists. What would be a good way to tell if it is empty. The returned value would be used to test.

Thanks...chuck

See the COUNT task (similar to unix 'wc'), e.g.

Code:


count ("/dev/null") | scan (nlines, nwords, nchars, fname)
if (nchars == 0) {
    # file is empty ....
}
