i tried the code below: not getting proper idea to do this.Hope some expert would help me.Thanks

#!/bin/sh
for file in `list.txt`
cp cat|list.txt > name

Details explanation: suppose we take 20180603_190202_5.0_38_CD.txt file to the consideration.This named file is already present inside /home/liu/datalist directory and it contains file like

1 2 3 4 5
5 6 7 8 9
3 4 5 6 7
3 4 5 6 7 
4 5 6 7 8

and i want the file to be as below

1 2 3 4 5 0.9821305886510053
5 6 7 8 9 0.9822639336394542
3 4 5 6 7 0.9820650754926169
3 4 5 6 7 0.9826369946635649
4 5 6 7 8 0.983048680372995

Code

$ cat test.sh 
#!/bin/bash

cat list.txt | cut -d '/' -f5- | sed "s/' mode='r' encoding='UTF-8'>//" > new_list.txt

while read -r line
do
  if [[ "$line" =~ ".txt" ]]; then
    count=0
    filename="$line"
    touch "$filename"
  else
    count=$(($count+1))
    originalline=$(sed -n ${count}p "$filename")
    sed -i "0,/^$originalline\$/s//$originalline $line/" "$filename"
  fi
done < "new_list.txt"

rm new_list.txt

Another solution using associative arrays:

#!/bin/bash

declare -A filetemp

while read -r line
do
    if [[ $line =~ "name='"(.*?.txt) ]]
    then
        name="${BASH_REMATCH[1]}"
        filetemp[$name]=$(mktemp)
    else
        [ -n "$name" ] && echo "$line" >> "${filetemp[$name]}"
    fi
done < list.txt

for name in "${!filetemp[@]}"
do
    paste -d ' ' "$name" "${filetemp[$name]}" > "${name}.tmp"
    mv -f "${name}.tmp" "$name"
done

EDIT: Forgot about this but, just in case, it would be a good idea to clean up the temporary files created by mktemp after they are no longer required:

for name in "${!filetemp[@]}"
do
    tempfile="${filetemp[$name]}"
    paste -d ' ' "$name" "$tempfile" > "${name}.tmp"
    mv -f "${name}.tmp" "$name"
    rm -f "$tempfile"
done

EDIT 2: As pointed by @lucasgvarela, the trap command could be a more elegant way of removing the temporary files when the EXIT signal is triggered:

trap 'rm -f "${filetemp[@]}"' EXIT

for name in "${!filetemp[@]}"
do
    paste -d ' ' "$name" "${filetemp[$name]}" > "${name}.tmp"
    mv -f "${name}.tmp" "$name"
done
