1: 查看log后20行的每行的前200字符
awk '{print substr($0, 0, 200)}' data.log | tail -20
2: awk 分割字符串
echo '1234qw212' | awk -F 'qw' '{print $1 "-" $2}'
1234-212
3: 按照文件每行長度排序
tset.txt
qwe
ewewew
qw
dedefefe
awk '{print $1 ":" length($1)}' test.txt | sort -n -t : -k 2 | awk -F ":" '{print $1}'

sudo service cron restart
ubuntu server設(shè)置時(shí)區(qū)和更新時(shí)間
記錄一下，以防忘記
