Hi
I am facing a problem in spitting a string.
Here is the string
--------------------
subject1=10;subject2=30;subject3=40;subjectcode=10001;...
Now, I want only marks not the subject code. (there can be 'n' subjects)
ie.
10
30
40
My doubt
----------
How do I look for subject'n'= (where 'n' is number). I want to ignore if there is any characters between subject and =.
Try:
echo 'subject1=10;subject2=30;subject3=40;subjectcode=10001;../..' |
tr ';' '\n' | sed -n 's/subject[0-9]\+=\([0-9]\+\)/\1/p'
10
30
40
$ nawk -F"[=;]" '{for(i=2;i<=NF;i=i+2)print $i}' test
10
30
40
10001
$ cat test
subject1=10;subject2=30;subject3=40;subjectcode=10001;

i didnt read your question properly... try the below ( test is the input file name )
$ nawk -F"[=;]" '{for(i=1;i<=NF;i++){ if($i~/subject[0-9]/) {print $(i+1)}}}' test
10
30
40
IFS=';'
set -f
set -- $string
set +f
for n
do
case $n in
subject*[!0-9]*=*) continue ;;
subject*) printf "%s\n" "${n#*=}" ;;
esac
done
Another option
awk -F"=|;" '{ for(i=2;i<=NF;i=i+2){print $i} }' infile

Ooops... please ignore the above code... I missed out the actual requirement...
My code also will boil down to itkamaraj's code...
