When executing this script
#!/bin/bash
/usr/bin/pgrep -f `/usr/bin/basename $0` && echo OK
echo $$
$$ gets written twice, as confirmed by
./proc.sh | grep '[[:digit:]]'
(assuming the script has been saved under the file proc.sh)
Expected behavior = $$ should be echoed only once.
Anyone else seeing this?
Is this normal?

The first $$ is printed by pgrep.
Please disregard.
Thank you.
