我使用varnishlog命令,並試圖篩選某些字段:如果我用另一個grep命令我得到空的結果使用兩個管道給空結果
sudo varnishlog -c | grep -E 'ReqURL|Varnish-Cache'
- ReqURL /sample/2
- RespHeader X-Varnish-Cache: HIT
- ReqURL /sample/2
- RespHeader X-Varnish-Cache: HIT
現在:
sudo varnishlog -c | grep -E 'ReqURL|Varnish-Cache' | grep 'HIT'
能否請您幫助我在這裏可能是什麼問題?該命令的
示例輸出:sudo varnishlog -c

嘗試將第一個grep模式包裝到括號中。像這樣:'(ReqURL | Varnish-Cache)'。也UNIX版本和varnishlog -c輸出的一部分將是非常有幫助 – sotona
你可以嘗試-u無緩衝輸出。像varnishlog -cu ... –
@sotona,我試過使用括號,但同樣的問題。我用命令的輸出樣本更新了我的帖子。 – user3181365
