Bug ID: 232201
Summary: sh(1): Using unset variables in here-doc with set -u
does not cause the script to exit
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
The output of sh(1) from the base and of dash from the ports (shells/dash) is
different.
Here's the script to reproduce this issue:
```
#! /bin/sh -
set -u
# Unset variable.
cat << EOF > /dev/null && echo ok || echo error
$unsetvar
EOF
```
Output of `sh test.sh`:
> testcase-2.sh: unsetvar: parameter not set
> ok
Output of `dash test.sh`:
> testcase-2.sh: 6: testcase-2.sh: unsetvar: parameter not set
> error
I'm running sh(1) from 12.0-ALPHA6 r338797 and dash 0.5.10.2 from ports.
