I read an array from another script. This array needs to put " "
around all array members since some members are empty.
in_file=./data
vector=($(./readdata.sh 0 $in_file))
for index in ${!vector[@]}
do
echo ${vector[index]}
done
The problem is that I have quotations around each output line and I want to get rid of them.
"red"
"blue"
"green"
""
"white"
"black"
must change to:
red
blue
green
white
black
I look for a method which does not use awk
, tr
, sed
or any other pipeline based way. I just want to solve with using native ways such as using parenthesis, different punctuations, ….
