[Solved] Bash scripting and sed substitution

Question

Hello!
I am writing a script in order to substitute strings from one array to another one in texts.
For only one case it is working as the following :
sed '/ā/s/\(.*\)ā\(.*\)/\1a\21/g' temp.txt > temp2.txt
which converts ā in a word by the same word with a normal "a" and the number 1 at the end of the word (māng > mang1)
For many cases i've made some arrays and containing the rules in a srcipt file :
# These are the 4 databases containing the strings that are suposed to be replaced
data1[1]=ā
data1[2]=ē
data1[3]=ī
data1[4]=ō
data1[5]=ū
data1[6]=ǖ
data2[7]=á
data2[8]=é
data2[9]=í
data2[10]=ó
data2[11]=ú
data2[12]=ǘ
data3[13]=ǎ
data3[14]=ě
data3[15]=ǐ
data3[16]=ǒ
data3[17]=ǔ
data3[18]=ǚ
data4[19]=à
data4[20]=è
data4[21]=ì
data4[22]=ò
data4[23]=ù
data4[24]=ǜ
# This is the data base of output correspondances
data[1]=a
data[2]=e
data[3]=i
data[4]=o
data[5]=u
data[6]=ü
count=1
for base in {1..4} # For each database
do
for case in {1..6} # For each case
do
sed "/${data${base}[$count]}/s/\(.*\)${data${base}[$count]}\(.*\)/\1${data[$case]}\2$base/g" temp.txt > temp2.txt
let "count+=1" #go to the next case in the database
cat temp2.txt > temp.txt
done
done
I have a substitution issue in the sed line. In fact I am trying to make a double substitution and it doesn't works.
Like the first substitution ${data${base}[$count]} make 3 substitutions at a time… but I can't make it to work.
In that case it would give me, for instance, the string contained in data2[3].
I hope you understand what i mean. And i'd like to know how to deal with that substitution issue if you have an idea…

Answer 1

I've implemented what Procyon told in the part 2 and it's working with a small adaptation, which is great!!
I've just an issue now because the number will go right after a word but at the end of the ligne… even if words are spaced by a space… like :
hǎo
hào
wō wó wǒ wò wo
become :
hao3
hao4
wo wo wo wo wo1234
my sed ligne is now :
sed "/$(eval echo \$\{data$base[$count]\})/s/\(.*\)$(eval echo \$\{data$base[$count]\})\(.*\)/\1${data[$case]}\2$base/g" temp.txt > temp2.txt
