shell脚本之生成任务列表

拓扑，配置，事务，任务都生成好了，需要一个下载文件来描述。

针对每一个任务，有两项足以描述:

第一：要下载的配置信息，其实也就是一个任务的事务中的配置列表，当然是有序的，以及每一个配置节点的信息。

第二：要下载给的对象，给谁下载，也就是主机-群组列表

 

配置用polist来描述

设备用device来描述

 

每个任务的目录下有两个文件，就足以表征这任务了。

比如:

tree data/download/1*
data/download/18
|-- device
`-- polist
data/download/19
|-- device
`-- polist

这样描述了ID为18和19的两个任务的所有信息。

其中，配置信息为:

 

cat data/download/18/polist
[general]
name=app1
group=3
time=1_2011-07-04_00_00
transid=46

[idex_0]
polid=75
index=1
depend=1

还有主机列表为:

 

cat data/download/18/device
[dev_0]
group=3
devname=214vm
devid=1
devip=3591643146

[dev_1]
group=3
devname=vmlinux14
devid=4
devip=241573898

每个任务目录下的文件格式都是一样的。

拥有这两个文件，就能完成每个任务的发送工作。

下面是生成脚本:

ge_app.sh

 

mkdir -pv "data/download" > /dev/null 2>&1
tmpfile="data/`echo $$`.txt"
unlink "$tmpfile" > /dev/null 2>&1
touch "$tmpfile"

# the code below is used to export all application list
# the result is saved in "data/download/XXX" XX is the id of each application
#
ls data/application | while read appid

    unlink "$tfile" > /dev/null 2>&1
    touch "$tfile" > /dev/null 2>&1
    #check file "group"
    if ! [ -f "$tdir/group" ]
    then
        echo "can not find file 'group' in directory '$tdir'"
        continue;
    fi
    group=`cat "$tdir/group"`

    #save group list to get device list

    if ! [ -f "$tdir/time" ]

        continue;
    fi

    then

        continue;
    fi
    transid=`cat "$tdir/transid"`

        echo ""     >> "$tfile"
