Bash Version: 4.4
Patch Level: 0
Release Status: release
Description:
I have a script that execute `if [[ "$(<"/proc/$1/cmdline")" = tmux*
]];`.
All /proc/*/cmdline include null bytes, and as of Bash 4.4, this
results in
a warning being spewed on stderr which did not happen in Bash 4.3.
Repeat-By:
echo "$(<"/proc/$$/cmdline")"
Fix:
Is this even an intentional change? I looked at some of the other
internal_warning invocations, and they were commented out using "#if 0
...
#endif."
