More convenient thah having to recall what letter is about showing/listing/dumping the configuration, i.e. no arguments means -l/--list: # perf config llvm.dump-obj=true trace.default_events=/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o trace.show_zeros=yes trace.show_duration=no # perf config -l llvm.dump-obj=true trace.default_events=/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o trace.show_zeros=yes trace.show_duration=no # perf config -h Usage: perf config [<file-option>] [options] [section.name[=value] ...] -l, --list show current config variables --system use system config file --user use user config file # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Taeung Song <treeze.taeung@gmail.com> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-z2n63avz6tliqb5gmu4l1dti@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
