Subject: [PATCH] journalctl: quit on I/O error
|
||
|
|
|
||
|
|
This makes journalctl quit on ferror() conditions on stdout. It fixes an
|
||
|
|
annoying bug if you pipe its output through 'less' and press 'q'. Without
|
||
|
|
this fix journalctl will continue reading all journal data until EOF which
|
||
|
|
can take quite some time. For instance on my machine:
|
||
|
|
|
||
|
|
david-nb ~ # time journalctl | wc -l
|
||
|
|
327240
|
||
|
|
|
||
|
|
real 1m13.039s
|
||
|
|
user 1m0.217s
|
||
|
|
sys 0m10.467s
|
||
|
|
|
||
|
|
However, expected behavior is journalctl to quit when its pager closed the
|
||
|
|
output pipe.
