I have noticed some unusual behavior while running the script.
when i use below script it gives output 355.23
Code:
#!/bin/bash
ONEDAY=`date +%Y%m%d --date="1 days ago"`
cat /opt/occ/var/performance/counters_`date -d "1 day ago" +%Y%m%d`*|grep "Gy,Gy-Gy-CCR"|awk -F"," '{print $1,$7}'|awk '{if (last && $2 != last) {print last, sum; sum=0} sum=sum+ $3; last = $2} END {print last, sum}' > GY_DATA_$ONEDAY
for line in `cat GY_DATA |awk '{print $2}'`; do cv=$line; diff=`echo "$cv - $lv"|bc`;lv=$cv; echo "$diff"; done|sed '1d'|sort -g|tail -1|awk '{print $1/300}' > GY_TPS_$ONEDAY
however when i run below part manually i get different output. which is 352.12.
Code:
by saying manually I mean I pasted the content on terminal
Code:
cat /opt/occ/var/performance/counters_`date -d "1 day ago" +%Y%m%d`*|grep "Gy,Gy-CCR"|awk -F"," '{print $1,$7}'|awk '{if (last && $2 != last) {print last, sum; sum=0} sum=sum+ $3; last = $2} END {print last, sum}' > GY_DATA
for line in `cat GY_DATA |awk '{print $2}'`; do cv=$line; diff=`echo "$cv - $lv"|bc`;lv=$cv; echo "$diff"; done|sed '1d'|sort -g|tail -1|awk '{print $1/300}' > GY_TPS
now after running it manually, when i run my script again it get the same value everytime which 352.12.
now i an unable to understand why i am getting such a behavior from same content.
after running it manually once even if i rum my script n times i get the same result .
the content is same, the only difference is one is scripted and another is run manually by me.
please help and suggest me what is going wrong
Please become accustomed to provide decent context info of your problem.
It is always helpful to support a request with system info like OS and shell, related environment (variables, options), preferred tools, and adequate (representative) sample input and desired output data and the logics connecting the two, to avoid ambiguities and keep people from guessing.
On the first glance, the output files are different, but input files aren't.

sometimes it become really very difficult to explain the problem .
please let me know in case you found anything unclear.
Not sure how much clearer I can make it: PLEASE post a sample (i.e. a few lines) of your input data so people in here can run your commands against it. How else do you expect people to test your script and error description?
