I don't think this is the problem, == and = both work in this case, the
if statement does not check the return value of the command (bash
function) CheckPolicy but the stdout
from the bash manpage:
string1 == string2
True if the strings are equal. = may be used in place of == for
strict POSIX compliance.
Demo script:
#!/bin/bash
function CheckPolicy() {
echo 0
}
CheckPolicy
if [ `CheckPolicy` = 0 ]; then echo null;else echo one; fi
if [ `CheckPolicy` == 0 ]; then echo null;else echo one; fi
function CheckPolicy() {
echo 1
}
CheckPolicy
if [ `CheckPolicy` = 0 ]; then echo null;else echo one; fi
if [ `CheckPolicy` == 0 ]; then echo null;else echo one; fi
======
When run this outputs the following:
0
null
null
1
one
one
