Start with that. Without seeing your...

The find command doesn't return anything, so the variable i cannot assume any value and the do ... done branch is not executed.

The files matching the pattern *GPX.Z are compressed text files or directories?
You could try:

find /comptel4/elink/backup1/output/vas/NG0/2013030[1-7]/ -type f -name '*GPX.Z' | xargs zgrep -f...

Good find :) :b:

done < msisdn_u.txt

Will this cause the same? :wall:

You can modify your script..

for i in $(ls -1)
do
length=$(awk 'END{printf "%036d", NR}' $i)
dur=$(awk '{s+=substr($0,85,9)}END{printf "%09d\n", s } ' $i)
#Please read more about sed...

awk ' /^[0-9]/{s+=substr($0,85,9)}END{printf "%09d\n", s } ' filename
With code tags, the data looks different! No need for condition, just action:
awk '{s+=substr($0,85,9)}END{printf "%09d\n", s }...

From left to right:
sed -n "s/.*_\([0-9]\{8\}\).*\.jar$/\1/p"
sed - Stream editor
-n - Suppress normal action which is to print all lines
"s/ - Start search/replace pattern
. - Match...
