I have a code:

flag=true

if cmp -s item1 item2 ; then
   if test flag = true; then
      echo 'a'
   else 
      echo 'b'
   fi
fi

and for somereason only the else is triggered and I get 'b', why is that?

because "flag" is not equal to "true" – jhnc Mar 24 '19 at 23:23

You want $flag = true – Mike Wodarczyk Mar 24 '19 at 23:24

...or, rather, `test "$flag" = true`, with the quotes; otherwise you get a syntax error from `test` if `flag` is empty. – Charles Duffy Mar 24 '19 at 23:30

BTW, http://shellcheck.net/ would have told you that your `flag` variable was unused if you submitted it this code. – Charles Duffy Mar 24 '19 at 23:32
