[Solved] bash on pi3B+ stretch; shell script to fork ‘ program &’ –bash cannot find file. It IS there

John Loop Asks: bash on pi3B+ stretch; shell script to fork ‘ program &’ –bash cannot find file. It IS there
Have tried variations with/without ‘ and &, spelling full path, adding to $PATH. The script cannot seem to find hyperping, tho it is in the same directory as the script which is calling it. Executing as user pi. Pulling my hair OUT!! Actual line in script

Code:
if [ $(/usr/bin/pgrep -c hyperping) -eq 0 ]; then './hyperping &'; fi

“hyperping” is in PATH [verified via $PATH, also via removing &]

Code:
***pi@pi20:~/tests $ ls -lt hyperping
-rwxr-xr-x 1 pi pi 692 Jul 30 13:10 hyperping***

“hyperping” runs fine called independently.

output of bash with “set -xv”

Code:
***/++ /usr/bin/pgrep -c hyperping
+ '[' 0 -eq 0 ']'
+ '/home/pi/tests/hyperping &'
./at7PM: line 33: /home/pi/tests/hyperping &: *No such file or
directory*/****
