I am writing a simple script to check if the certificate for a website is valid. However, when I attempt to run the code in terminal, I receive an error message stating that the command openssl cannot be found. Here is the code:

if true | openssl s_client -connect www.google.com:443 2>/dev/null | \
  openssl x509 -noout -checkend 0; then
  echo "Certificate is not expired"
else
  echo "Certificate is expired"
fi

When I attempt to run this code, I receive this output:

./check-certificates.sh: line 6:  openssl: command not found
Certificate is expired

The code runs, but it does not recognise openssl as a valid command, so it skips over the line of code where this is mentioned, and defaults to outputting "Certificate is expired".

When using sudo apt-get install openssl I receive this message:

...
openssl is already the newest version (1.0.2g-1ubuntu4.15).
...

So it looks like openssl has been successfully installed. I'm at a loss on how to fix this - does anybody have any ideas?

EDIT #1:

As requested, here is the output of apropos openssl | grep "OpenSSL command line tool"  : openssl (1ssl) - OpenSSL command line tool

And locate openssl | grep /usr/bin  : usr/bin/openssl
