The original picture is in the local, the outward guide picture is particularly simple, as long as the execution of the CP script is good, but now the pictures are migrated to seven cattle, and then export the picture on the trouble in seven cattle have a qshell tool inside there is a qdownload
| Qdownload |
Synchronizing data from seven cow space to local, supporting files that only have certain prefixes synchronized, support incremental synchronization |
Qshell qdownload qdownload.conf is so used qdownload.conf for the configuration file inside there is such a configuration, the other configuration is not given. "prefix" : "", fill in the image prefix to my file is this, cp/root/export_files/1025168/ Dfeafa0a-6f96-4b32-88c1-dde103b3655a/1453366970085.jpg/root/export_files/8155-003f-3115.jpg altogether more than 2000 Zhang ...
