Subject: tests: avoid SIGPIPE
X-Git-Tag: v4.6~15
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f9a84ef39fdbfe9636837c99beff52d62a7b8127;p=strace

tests: avoid SIGPIPE

* tests/ptrace_setoptions: Replace "grep -q" with "grep > /dev/null".
The former may result to strace being killed by SIGPIPE, which in
certain configuratons may lead to generation of a core file.
Suggested by Mike Frysinger.
