wc -l only returns one number. On Wed, 17 Feb 2021, Linux for blind general discussion wrote:
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): realcj=${cj%% *} or 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.

I wanted to get a line count into a variable and bash doesn't like what I'm doing to make that happen. The code is: let "cj=`wc -l chk-jenux.log`"
