Bash - While read line from file print first and second column [closed]

Answer 1

If it's a small file, you can use read to split the line.

while IFS=, read fruit count; do
  echo "I have $fruit and the count is $count"
done < file.txt

For larger files, it is inefficient to iterate using bash, and something like awk to read the entire file would be more appropriate.

Answer 2

You can use awk like this:

awk -F, '{print "I have", $1, "and the count is", $2}' file

I have apple and the count is 2
I have mango and the count is 5
I have coconut and the count is 10

Though awk is recommended but if you are looking for a bash loop then use:

while IFS=, read -r f c; do
    echo "I have $f and the count is $c"
done < file

Answer 3

Here is one in sed. Replace the beginning of each line and the comma with related strings:

$ sed 's/^/I have /;s/,/ and the count is /' file
I have apple and the count is 2
I have mango and the count is 5
I have coconut and the count is 10
