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
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 -N5. 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
