Protokolle dynamisch anzeigen
tail -f catalina.out
Öffnen Sie die Protokolldatei von Anfang an
cat catalina.out
Sie können >nanjiangtest.t verwenden xt zur Ausgabe Ein neues Protokoll zum Anzeigen von
[root@yesky logs]# cat -n catalina.out |grep 717892466 >nanjiangtest.txt
[root@yesky logs]# tail -n number catalina.out 查询日志尾部最后number行的日志[root@yesky logs]# tail -n +number catalina.out 查询number行之后的所有日志[root@yesky logs]# head -n number catalina.out 查询日志文件中的前number行日志[root@yesky logs]# head -n -number catalina.out 查询日志文件除了最后number行的其他所有日志
Verwenden Sie grep, um sehr wenige Protokolle zu erhalten. Wir müssen in der Nähe nachsehen Protokolle. Folgendes habe ich zuerst getan: cat -n test.log |. grep „keyword“, um die Zeilennummer des Schlüsselprotokolls zu erhalten
