Title:
Unbound variables can't be checked with -z anymore
Status in bash package in Ubuntu:
Incomplete
Bug description:
I'm using Ubuntu 14.04 dev with bash 4.3-4ubuntu1 and if bash is
started with the -u parameter any check of unbound variables will
raise an unbound exception. Here is a testcase:
#!/bin/bash -u
if [ -z $SOME_UNINITIALIZED_VARIABLE ]
then
echo Variable uninitialized
fi
Executing this script will result in this output: "./test.sh: line 3:
SOME_UNINITIALIZED_VARIABLE: unbound variable"
