Question

I created this script and I want to print the outputs on one line, how do I do this?
This is my script

#!/bin/bash

echo "enter start and stop numbers"

read start stop

while [ $start -lt $stop ]

do

echo $start

start=`expr $start + 1`

done

Answer 1

Using printf or echo -n. Also, try to use start=$(($start + 1)) or start=$[$start + 1] instead of back ticks to increment the variable.

#!/bin/bash

echo "enter start and stop numbers"
read start stop
while [ $start -lt $stop ]
do
    printf "%d " $start
    start=$(($start + 1))
done

#!/bin/bash

echo "enter start and stop numbers"
read start stop
while [ $start -lt $stop ]
do
    echo -n "$start "  # Space will ensure output has one space between them
    start=$[$start + 1]
done
