1. 按时间先后，列出最后的十个目录
ls /mnt/daily/Concord/main -sort -t | awk /_[0-9]+-[0-9]/'{print $NF}' | tail -10 /mnt/daily/LotusLive目录内容如下： SC10.0_Docs :dir SC10.0_DocsProxy :dir SC20.0_Docs :dir SC20.0_DocsProxy :dir SC30.0_Docs :dir SC30.0_DocsProxy :dir SC30.16_Docs :dir SC30.16_Viewer :dir tsm_backup :file run 如下命令后：find /mnt/daily/LotusLive -mindepth 1 -maxdepth 1 -type d | sort | awk -F '[/]' '{print $5}' | awk -F '[_]' '/SC[234]/{print $1}' | uniq显示： SC20.0 SC30.0 SC30.16
2. 递归删除空目录
# $1必须是绝对路径 crurl=$1 func_hdir(){ echo $crurl cd $crurl for aitem in `ls -l | grep "^d" | awk '{print $9}'`; do crurl=$crurl/$aitem func_hdir $aitem done dirc=`ls $crurl` if [ "$dirc" = "" ] then echo $crurl rm -rf $crurl fi crurl=${crurl%/*} } func_hdir
3. sed删除特定的行 sed -e '/^[ ]*$/d' osgi_file > target_file //删除空行 sed -d '/concord/d' osgi_file>target_file//包涵concord的行 4. 输出最新的N个目录， find /mnt/daily/Concord/main -mindepth 1 -maxdepth 1 -type d -printf "%T@%Tx %p" | sort -n -r | head -N 5. 输出最近5天创建的目录 find /mnt/daily/Concord/main -mindepth1 -maxdepth 1 -type d -mtime -5 -mtime 最大数是8，超过8就是输出全部 6. sort by 特定列 如当前工作中的应用，以MSG_NODE_%d排序，可用如下命令 find . -type f -name envconfs.conf | grep -v "chatroom"| grep "appnodemessagepool"| sort -t '.' -k4 find . -type f -name envconfs.conf|grep "appnodemessagepool"|sort -t '/' -k2 ./com.rcloud.appnodemessagepool.MSG_NODE_3/conf/envconfs.conf ./com.rcloud.appnodemessagepool.MSG_NODE_4/conf/envconfs.conf ./com.rcloud.appnodemessagepool.MSG_NODE_5/conf/envconfs.conf
