1. CLIENTS="monitor net-test net-db-test cache-test"
   
2. SERVICES="system mysql redis"
   
3. 
   
4. # create rsync dir
   
5. for dir in `cat /etc/rsyncd.conf | grep "^path =" | awk -F " " '{print $3}'`; do
   
6.     mkdir -p $dir
   
7.     if [ "${dir##*/}" = "log" ]; then
   
8.         for client in $CLIENTS; do
   
9.             for serv in $SERVICES; do
   
10.                 mkdir -p $dir/$client/$serv

1. [root@host-test backup]# cat /etc/rsyncd.conf | grep "^path =" | awk -F " " '{print $3}'
   
2. /backup/database
   
3. /backup/data
   
4. /backup/log

"${dir##*/}" = "log"这句是什么意思

seesea2517

1. [seesea@UC ~]$ for dir in /backup/database /backup/data /backup/log; do echo "$dir -> ${dir##*/}"; done;
   
2. /backup/database -> database
   
3. /backup/data -> data
   
4. /backup/log -> log

这样能看明白不？

详细可在论坛shell版搜索：变量替换。
