Iterate print for each line in output

Question

I want to print uvuveve at finish each line, for each output into while statement, as below:

var1;var2;uvuveve
var1;var2;uvuveve
var1;var2;uvuveve
var1;var2;uvuveve
var1;var2;uvuveve

This is my code:

var1="somedata..."
var2="anotherdata..."
while read -u3 w1; read -u4 w2; do
echo "$w1;$w2" >> $file
done 3<<< "$var1" 4<<<"$var2"

var1, var2 print multiple occurrences of a file, so there are many outputs by these variables. I tried to add uvuveve word like this way:

var1="somedata..."
var2="anotherdata..."
string="uvuveve"
while read -u3 w1; read -u4 w2; read -u5 w3; do
echo "$w1;$w2;$w3" >> $file
done 3<<< "$var1" 4<<<"$var2" 5<<<"$string"

Essentially, I need a print of the word in each line, for each occurrence founded.

Adding Details:

Var1 & var2 retrieve lines of occurrences that a file contains, and then put into variables

Literally the lines are:

var1=$(grep -A12 -B12 "$tofind" $findlogs | grep Date | cut -c 51-65 | sed -e 's! !/!g')
var2=$(grep -A12 -B12 "$tofind" $findlogs | grep Date | cut -c 67-71 | sed -e 's/://g')

Answer 1

Since you just have plain text in variables, redirecting them into a while-read loop seems ridiculously over-complicated.

What's wrong with

var1="somedata..."
var2="anotherdata..."
string="uvuveve"

echo "$var1;$var2;$string"
# or
printf '%s;%s;%s\n' "$var1" "$var2" "$string"

If you actually have files, then you do need a loop. If we have

$ cat file1
a
b
c
$ cat file2
1
2
3

then

string="uvuveve"
while IFS= read -r -u3 a; read -r -u4 b; do 
    printf '%s;%s;%s\n' "$a" "$b" "$string"
done 3<file1 4<file2

a;1;uvuveve
b;2;uvuveve
c;3;uvuveve

---

Going back to your edit: use Process Substitutions

# don't repeat yourself
dates=$(grep -A12 -B12 "$tofind" $findlogs | grep Date)
string="uvuveve"
while IFS= read -r -u3 a; read -r -u4 b; do 
    printf '%s;%s;%s\n' "$a" "$b" "$string"
done 3< <(echo "$dates" | cut -c 51-65 | sed -e 's! !/!g') \
     4< <(echo "$dates" | cut -c 67-71 | sed -e 's/://g')

Answer 2

Does this do what you want?

#!/usr/bin/env bash
IFS=$'\n'; var1=( $( ... your command here ... ) );
IFS=$'\n'; var2=( $( ... your command here ... ) );

for i in ${!var1[@]}; do
  echo ${arr1[$i]};${arr2[$i]};uvuveve
done

It assumes that var1 and var2 have the same amount of lines.

Basically:

1. We turn your command into a variable that is an array. source
2. Then we iterate the array (source) adding the variables together and your extra string.

Tried with below command

$ j="praveen"
$ k="ajay"
$ m="abhi"

$ awk -v j="$j" -v k="$k" -v m="$m" '{print j"\n"k"\n"m;exit}'
praveen
ajay
abhi
