Progress bar using lsof and awk

Shell Programming and Scripting
1

Hey all. I added this to my script, hoping for a progress bar or percentage complete

lsof -o0 -o -p $$ |
awk '
            BEGIN { CONVFMT = "%.2f" }
            $4 ~ /^[0-9]+r$/ && $7 ~ /^0t/ {
                    offset = substr($7, 3)
                    fname = $9
                    "stat -f %z '\''" fname "'\''" | getline
                    len = $0
                    print fname, offset / len * 100 "%"
            }
    '           

unfortunately,  this is what i see in my terminal:
Please wait while the task completes
/bin/sh: Syntax error: Unterminated quoted string
pipe nan%
/home/bj/Desktop/Final_JCATS_userin2.sh inf%

can anybody out there see what i'm doing wrong? I'm pretty sure that the error is in the awk portion of the script, considering it wasn't there prior to the addition of it. Thanks!

Try :

lsof -o0 -o -p $$ |
awk '
            BEGIN { CONVFMT = "%.2f" }
            $4 ~ /^[0-9]+r$/ && $7 ~ /^0t/ {
                    offset = substr($7, 3)
                    fname = $9
                    "stat -f %z " Q fname Q | getline
                    len = $0
                    print fname, offset / len * 100 "%"
            } 
    ' Q="'"

That was by far the quickest reply I have every gotten on a forum. I really appreciate it aigles!!!

unfortunately, now i'm getting this error. I apologise if it's something simple. I'm still new to scripting and trying to feel my way through.

./Final_JCATS_userin2.sh: line 110: unexpected EOF while looking for matching `"'
./Final_JCATS_userin2.sh: line 114: syntax error: unexpected end of file

Sorry, the definition of the variable Q is misplaced.
The correction have been made in my previous post.

Well Sir, I'm back to the Unterminated quoted string...

/bin/sh: Syntax error: Unterminated quoted string
pipe nan%
/home/bj/Desktop/Final_JCATS_userin2.sh inf%

The problem is not in the portion of script of the post.

$ cat wrk.sh
lsof -o0 -o -p $$ |
awk '
            BEGIN { CONVFMT = "%.2f" }
            $4 ~ /^[0-9]+r$/ && $7 ~ /^0t/ {
                    offset = substr($7, 3)
                    fname = $9
                    "stat -f %z " Q fname Q | getline
                    len = $0
                    print fname, offset / len * 100 "%"
            } 
    ' Q="'"
$ sh -n wrk.sh
$

Show us the full script code.

Here is everything i have in my script right now...

then
echo "File exists"
break
else
echo "Try again"
fi

then
echo "exceeded 5 tries. quitting"
exit
