More verbosity without welcome message #4565
Description
When compressing from stdin, it would be nice with an option to see the progress without the WELCOME_MESSAGE.
Especially in scripts that invoke zstd many times.
Current behaviour:
ls -l |zstd -9 -v > ll.zst
*** Zstandard CLI (64-bit) v1.6.0, by Yann Collet ***
/*stdin*\ : 36.23% ( 1.17 KiB => 434 B, /*stdout*\)
Proposed:
ls -l |zstd -9 -v > ll.zst
/*stdin*\ : 36.23% ( 1.17 KiB => 434 B, /*stdout*\)
ls -l |zstd -9 > ll.zst
[shows nothing - both before and after change]
Proposed simple solution:
diff --git a/programs/zstdcli.c b/programs/zstdcli.c
index 01760ff8..86ea5a10 100644
--- a/programs/zstdcli.c
+++ b/programs/zstdcli.c
