Hello. I should have asked this awhile ago but here is my situation. My task is to generate LOC for different directories. I have a text file that has dates in this format (01-Aug-2006). My task is to read each line and compare it to a branch date. Depending on the date, it should generate a particular config_spec. Once that is done, another script loads the config_specs one by one and performs LOC counts. Here is the first step:
Code:
#!/bin/ksh
#THE OBJECTIVE OF THIS SCRIPT TO READ IN A TEXT FILE THAT #CONTATINS DATES IN A DD-MMM-YYYY FORMAT. EACH LINE IS READ AND #THE DATES ARE COMPARED TO A BENCHMARK DATE. DEPENDING ON THE #DATE, A CONFIG SPEC IS CREATED AND THAT CONFIG SPEC IS USED
#BY ANOTHER SCRIPT TO PRODUCE THE METRICS OF PROGRAM CODE ON THE SYSTEM.
#NOW, WE OPEN THE TEXT FILE
exec 3<week_ending_dates.txt
#HERE BEGINS A WHILE LOOP. AS THE FILE IS BEING READ LINE BY LINE, #EACH DATE IS READ AND THEN THE DATE IS TRUNCATED INTO THREE #VARIABLES. NEXT, THE VARIABLE, MONTH, IS TESTED AND SET TO A #NUMERICAL VALUE.
while read -u3 LINE
do
day=$(echo $LINE | cut -d'-' -f1)
month=$(echo $LINE | cut -d'-' -f2)
year=$(echo $LINE | cut -d'-' -f3)
case $month in
Jan*)month=01;;
Feb*)month=02;;
Mar*)month=03;;
Apr*)month=04;;
May*)month=05;;
Jun*)month=06;;
Jul*)month=07;;
Aug*)month=08;;
Sep*)month=09;;
Oct*)month=10;;
Nov*)month=11;;
Dec*)month=12;;
esac
#THE DATE IS NOW PUT BACK TOGETHER TO BE COMPARED TO THE #BENCHMARK
testdate=$year$month$day
branchdate="20070814"
# IF THE DATE WE ARE TESTING IS OLDER THAN THE BENCHMARK, CREATE A PARTICULAR CONFIG_SPEC. OTHERWISE, PRINT THE OTHER TYPE OF CONFIG_SPEC
if [[ $testdate -lt $branchdate ]]
then
echo 'Generating config spec files........'
more week_ending_dates.txt | grep Jan | awk '{ print "time "$1 " \n element * .../wint_sp75_dev/LATEST \n element * .../main/LATEST " > "config_"$1}'

done
exec 3<&-
Here are my issues and questions:
a) instead of finding the month, the script goes through all the lines of code (if Jan was read in, it will go through the rest before exiting. how do i break when the month is found/
b) when i read in dates, it seems that one particular config-spec is assigned to all dates (this includes dates that should be a different config-spec). how do i ensure that the config-spec changes accordingly.
c) is there an effecient way to accomplish my task.
Thanks for your help.

can anyone tell me the working of this logic.
here "last" is a variable or it has it own meaning . getting confused.
awk '{if (last && $2 != last) {print last, sum; sum=0}
sum=sum+ $3; last = $2}
END {print last, sum}' (4 Replies)
