need to read lines in file and compare value in if not working
Hello,
I have this file that sometime contains 0 lines and sometimes 1 or more.
It's supposed to then put the result (could be 0 or 1 or 2 or more) into a variable.
Then it's supposed to echo using an if else statement depending on the value of the variable.
The problem is that the tempfile contains 2 rows and it always echoes that
"the file does no have rows."
I've tried $flagvar != "0", I'm wondering if the condition should be a string since the result is printed from awk. (if the "0" is correct).. it I just used the value 0 without the quotes this would just be like $flagvar!=true which is not equal to true.
