shell按时间段进行日志筛选

筛选15:05--15:10期间的日志

•  使用sed 

sed -n '/Apr 22 15:05/,/Apr 22 15:10/p' syslog > test

• 使用grep，与sed提取的行数有差异，待查验。

grep -E '^Apr 22 15:05|^Apr 22 15:06|^Apr 22 15:07|^Apr 22 15:08|^Apr 22 15:09|^Apr 22 15:10'

• 使用awk，跟grep提取行数一致，不过会因为分隔符原因，时间戳格式被修改，需要额外辨别，待完善。

awk -F'[:]' '$1 = 15 && $2 >=5 && $2 <= 10 {print $0}' syslog 

日志格式：
