How to test if a string exists in a file and if so, check the remaining lines in the file for another string with bash shell

I already have a log say file.txt.

I will like to check in Bash, if a string (July) exists in the log and if so, check the remaining lines in the log for another string (foobar).

if you have awk available, an awk oneliner could do it for you:

awk '/July/{f=1} f&&/foobar/{print "Found foobar after July!";exit}' file

if no July or no foobar after July, the command prints nothing. of course you could make an if-else, to let it print "not found" or something.
