echo $basedir

cat /backup/3306/cycle_file
BASE_ID=base-2018-06-11-1203
INCREMENTAL_STEP=20534973839
LAST_LSN=2
获取到等号后面的位置：
grep INCREMENTAL_STEP /backup/3306/cycle_file | cut -d= -f2 20534973839 grep BASE_ID /backup/3306/cycle_file| cut -d= -f2 base-2018-06-11-1203 grep LAST_LSN /backup/3306/cycle_file | cut -d= -f2 2

获取INNODB的Last checkpoint at:
mysql -e 'show engine innodb status\G'|grep 'Last checkpoint at'|awk '{print $NF}'; 20544229853 [root@baige_mysql_bj_sjs_10_71_183_144 mysql_xtrabackup]# mysql -e 'show engine innodb status\G' Log sequence number 20547216141 Log flushed up to   20547215666 Pages flushed up to 20544229853 Last checkpoint at  20544229853

参数之f3,砍断后第三节，如下：

$git branch -a|grep -v "*" | grep -v ">"
  master
  remotes/origin/dev
  remotes/origin/master


Cut上来：

$git branch -a|grep -v "*" | grep -v ">"|cut -d "/" -f3
  master
dev
master



sed 去空格和Tab：

git branch -a|grep -v "*" | grep -v ">"|cut -d "/" -f3|sed "s/^[ \t]*//g"



去掉重复行：

$git branch -a|grep -v "*" | grep -v ">"|cut -d "/" -f3|sed "s/^[ \t]*//g"
master
dev
master



按正顺序sort:(反着排序 -r)

$git branch -a|grep -v "*" | grep -v ">"|cut -d "/" -f3|sed "s/^[ \t]*//g"|sort
dev
master
master



uniq上来去重：

git branch -a|grep -v "*" | grep -v ">"|cut -d "/" -f3|sed "s/^[ \t]*//g"|sort|uniq



防止太多，限制10条，head -10上来：

git branch -a|grep -v "*" | grep -v ">"|cut -d "/" -f3|sed "s/^[ \t]*//g"|sort|uniq|head -10




当然，还有更简单的，不用git branch -a:
主要是了解命令：

$git branch |sed "s# ##g"|sed "s#*##"
dev
master
