Grep from a file variable
I am wanting to test the output from a script. If the out put = Object does not exist. I need to delete the output file.
I am using , filecontents=`grep -i Object does not exist. $1.txt`
then I test the variable with,
if [ ${filecontents} = "Object does not exist." ]; then
delete file
But I get an error, grep: can't open leave_crew_allow_v.txt. Where leave_crew_allow_v.txt is the actual name assigned to the variable.

All I want to do is find out if the string 'NO' is in a file by checking for a return code of 0 if there is a match. The grep works fine on the command line directly naming the file but I am obviously not using the correct syntax within the shell script as I consistently get the error message

DESCRIPTION
In situations where you have deep trees of classes, there is a common situation in which you test a module 4 or 5 subclasses down, which
should follow the correct behaviour of not just the subclass, but of all the parent classes.
This should be done to ensure that the implementation of a subclass has not somehow "broken" the object's behaviour in a more general
sense.
"Test::Object" is a testing package designed to allow you to easily test what you believe is a valid object against the expected behaviour
of all of the classes in its inheritance tree in one single call.
To do this, you "register" tests (in the form of CODE or function references) with "Test::Object", with each test associated with a
particular class.
When you call "object_ok" in your test script, "Test::Object" will check the object against all registered tests. For each class that your
object responds to "$object->isa($class)" for, the appropriate testing function will be called.
Doing it this way allows adapter objects and other things that respond to "isa" differently that the default to still be tested against the
classes that it is advertising itself as correctly.
This also means that more than one test might be "counted" for each call to "object_ok". You should account for this correctly in your
expected test count.
