| #!/bin/bash | |
| A=$(date +%Y-%m-%dT%H-%M-%S) | |
| B=`date +%Y-%m-%dT%H-%M-%S` | |
| while true; do | |
| echo $A | |
| echo $B | |
| sleep 2 | |

I made the modifications as I had suggested:
sdake@beast-01:~/go/src/istio.io/test-infra$ more jwen.sh
#!/bin/bash
A=$(date +%Y-%m-%dT%H-%M-%S)
B=$(date +%Y-%m-%dT%H-%M-%S)
while true; do
echo A=$A
sleep 2
echo B=$B
done
and the result is
sdake@beast-01:~/go/src/istio.io/test-infra$ ./jwen.sh
A=2020-02-05T06-12-15
B=2020-02-05T06-12-15
A=2020-02-05T06-12-15
B=2020-02-05T06-12-15
A=2020-02-05T06-12-15
B=2020-02-05T06-12-15
A=2020-02-05T06-12-15
B=2020-02-05T06-12-15
A=2020-02-05T06-12-15
B=2020-02-05T06-12-15
A=2020-02-05T06-12-15
B=2020-02-05T06-12-15
A=2020-02-05T06-12-15
B=2020-02-05T06-12-15
A=2020-02-05T06-12-15
which looks like $(...) is working correctly...

move sleep from line 9 to preceed line 8. Have line 8 echo $A instead of $B.
