character limit via awk
I'm using a command that outputs the total size of the files that I've specified.
I'd like to introduce a character limit that appends an ellipsis to the lines that go beyond the specified amount.

Code:
du -chs {query} | sed 's!.*/!!' | awk '{print substr($0,0,25)"[...]"}'

That's what I have so far. It seems to add the ellipsis to the end of lines regardless of them being more or less than 25 characters. I'd only like to apple the limit to lines that go beyond the limit.

Try this to replace characters beyond 25th position:-

Code:
sed "s/^\(.........................\).*$/\1.../"

Thanks. I'm not sure why it didn't work when I first attempted.
