string comparison - Shell Programming and Scripting

fedora · #1 (**permalink**) 01-03-2007

The script will read a bunch of names, and test if it contains "John", but as below apparently ~ does not work, so what is the easiest way to perform string comparison in bash shell script? thanks

...
elif [ $name~"John"`"]
then
echo "get John"
....

Code:

if echo "dfdsdfsaf" | grep -q "sdf" ; then echo s; fi

if [ $var != ${var/john//} } 
then echo "John is inside :D "
else echo " no ( long ) john here " 
fi
