how to check the expiry of your certificate at linux

i updated my old SSL certificate with newer one. now need to know what is the expiry date of this certificate. 

lets see how to check expiry date of SSL certificate.

suppose you even don't know the path to certificate. 

# grep -r "^SSLCertificateFile" /etc/httpd/conf*

this output will tell you the path to your certificate file (in my case /etc/pki/tls/certs/mycertificate.file.crt)

# cd /etc/pki/tls/certs (or the path you found above)
# openssl x509 -in mycertificate.file.crt -noout -enddate

output might be like this
