Hello,
i experienced a problem with array element assignment.
The following script should read a text file and assign every line
beginning with the symbol '?' to the array U.
The script:
i=0
cat test.txt | while read s l ; do
case $s in
( '?' ) U[i]=$l ; ((i++)) ;;
esac
done
echo ${#U[*]}
Content of the input file 'test.txt':
? fragezeichen1
? fragezeichen2
? fragezeichen3
A alpha1
A alpha2
B beta1
? fragezeichen4
A alpha3
Output of the script (number of elements in array U):
0
Greetings
Homac
