Shell Programming and Scripting

Maybe this example helps use to make comparing little easier in shell. You can add breaks as you like.

Code:

for file in *.txt
do
    stat="DEPTH"
    while IFS="," read f1 f2 DEPT SDEPT rest
    do
        flag="DEPTH"
        ## between ((   and ))   you can use syntax same as like in C or ...
        ((   ( DEPT != 888 )  && ( DEPT !=0 )   ))  && flag="C1"    # && break # if like to break
       # if the 3rd column contains 55, 16, 76 and 4th column = 888 or 0 then it's the same as by CLASS
       # so write rule as it has been written:
         ((  ( DEPT == 55 || DEPT == 16 || DEPT == 76 ) && ( SDEPT == 888 || SDEPT == 0 )  )) && flag="C2"
       # if the 3rd column contains 55, 16, 76 and 4th column not equal 888 or 0 then it's the same as by CLASS
       # so write rule as it has been written:
         ((  ( DEPT == 55 || DEPT == 16 || DEPT == 76 ) && ( SDEPT != 888 && SDEPT != 0 )  )) && flag="C3"
        echo "      $flag - $f1 $f2 d:$DEPT sd:$SDEPT $rest"
        [ "$flag" != "DEPTH" ] && stat="CLASS"
    done < $file
    echo "$file - $stat"
done

(( ( DEPT != 888 ) && ( DEPT !=0 ) )) && flag="CLASS"
is same as

Code:

if ((   ( DEPT != 888 )  && ( DEPT !=0)   ))  
then
   flag="CLASS"
fi

hi kshji,

how about the 3 condition? 55,76 and 15?

In reaction to a recent PM:


Sorry but I'm stuck.

I'm afraid I can't help any further unless you give a clear picture of the overall problem. Appreciating that English might not be your first language (it's not mine either) and all the possible problems herewith, I do not understand what you need and where you're stuck.

In my post#4 I asked you to rephrase the problem AND supply decent, meaningful samples, which you did reluctantly only, and in pieces. Why can't you show the entire picture and the underlying structures?
- OS and shell used?
- What tools would be preferred (shell? awk/sed/perl? other?) or excluded?
- How many input files (you supplied several but different "file1.txt")?
- How many output files per input file?
- What's the logics/algorithms connecting the two?
- Attempts at solving the problem?
- Errors/messages/behaviour encountered when running either attempt?

Without a clear understanding of the situation, everybody (not only) in here will be shooting in the dark (which I did multiple times), and coming up with a fit solution would be sheer coincidence.

Did you even consider adapting the proposals supplied?
