how did you compile?

[tejasrao97]

shc -T -f shell script file name

shell hangs when I run the complied binary and also getting an operation not permitted error when I run as ubuntu user:
ubuntu@instance: shc -f sam.sh -v
shc shll=sh
shc [-i]=-c
shc [-x]=exec '%s' "$@"
shc [-l]=
shc opts=
shc: cc sam.sh.x.c -o sam.sh.x
shc: strip sam.sh.x
shc: chmod go-r sam.sh.x
ubuntu@instance: ./sam.sh.x
./sam.sh.x: Operation not permitted
Killed
ubuntu@instance: sudo su
root@instance:/home/ubuntu# ./sam.sh.x
^C

use sudo to run the script.
