Free Online Bash Terminal Problem.

[Arthur Dent]

I am getting problems with the following script when using

Bash mode in rexster, https://rextester.com/l/bash_online_compiler.

Either the variable assignment from the expression for result1

is not working, or the echo statement for result1 isn't working.

Can someone either fix rexster, if that is the problem, or tell

me what to do so that the 3rd output is the word 'jump"?

: '

var1="The quick brown fox jumps over the lazy dog.";

var2="jumps";

echo "----";

echo $var1 | grep -b -o $var2 | cut -d: -f1;

#echo $var1 | grep -b -o $var2 | cut -d: -f1;

result1=$var1 | grep -b -o $var2 | cut -d: -f1;

echo "----";

#20
echo $result1;

echo "----";

result2=${var1:result1:4};

#jump
echo $result2;

echo "----";

Hello,

1) During the tests, I suggest put the instruction at the beginning of the script:
set -x

2) Instruction

result1=$var1 | grep -b -o $var2 | cut -d: -f1

is not correctly

$result1 will return only value of $var1

3) correctly:

result1=$(echo $var1 | grep -b -o $var2 | cut -d: -f1)

now  $result1 will return 20

End the 3rd output will the word 'jump"
