the "wc" command is returning more than one word, is the problem with "let".
you don't need the "let" anyway, so:
cj=`wc -l chk-jenux.log`
would be enough. but if you want only the count of lines, you either have to
1: isolate the first word from "wc" (the line count):
2: do the "wc" without a file name:
cj=`cat chk-jenux.log | wc -l`
note that the first example has a few failure modes, although there are endless
other ways to isolate a given word from a multi-word string. i've always
used the second example.
