我正在寻找一个小的bash脚本,在启动时,查看任何新创建的文件的目录.如果出现新文件,我希望它的存在触发第二个脚本运行.
我看到这被用来触发压缩最近数字化的视频,并将其添加到摄取的镜头日志中.
目前我的代码如下所示：
#!/bin/sh
##VIDSTAT is a global variable coming from a parent script.
##proj is the ingestion directory coming from a parent script
proj=$1
dir="/home/$USER/data/movies/$proj"
dirlist=$(ls $dir)
while { $VIDSTAT -eq 1 }:
do
for mov in $dirlist
do
if [ "$(( $(date +"%s") - $(stat -c "%Y" $mov) ))" -lt "5" ]
then
~/bin/compressNlog.sh $mov
fi
done
done
有没有更容易/更清洁/更少内存密集的方式来做到这一点？
编辑我将改变每个捕获会话的摄取目录.我已相应调整了代码
解决方法
incron怎么样？它触发文件/目录更改命令.
sudo apt-get install incron
例：
<path> <mask> <command>
其中< path>可以是一个目录(意思是直接在该目录中的目录和/或文件(不是该目录的子目录中的文件！))或文件.
<掩模>可以是以下之一：
IN_ACCESS File was accessed (read) (*) IN_ATTRIB Metadata changed (permissions,timestamps,extended attributes,etc.) (*) IN_CLOSE_WRITE File opened for writing was closed (*) IN_CLOSE_NOWRITE File not opened for writing was closed (*) IN_CREATE File/directory created in watched directory (*) IN_DELETE File/directory deleted from watched directory (*) IN_DELETE_SELF Watched file/directory was itself deleted IN_MODIFY File was modified (*) IN_MOVE_SELF Watched file/directory was itself moved IN_MOVED_FROM File moved out of watched directory (*) IN_MOVED_TO File moved into watched directory (*) IN_OPEN File was opened (*)
<命令>是事件发生时应该运行的命令.可以在命令规范中使用以下通配符：
$$ dollar sign $@ watched filesystem path (see above) $# event-related file name $% event flags (textually) $& event flags (numerically)
如果你看一个目录,那么$@保存目录路径,$#保存触发事件的文件.如果您观看文件,则$@保存文件的完整路径,$#为空.
工作实例：
$sudo echo spatel > /etc/incron.allow $sudo echo root > /etc/incron.allow
启动守护程序：
$sudo /etc/init.d/incrond start
编辑incrontab文件
$incrontab -e /home/spatel IN_CLOSE_WRITE touch /tmp/incrontest-$#
测试一下
$touch /home/spatel/alpha
结果：
$ls -l /tmp/*alpha* -rw-r--r-- 1 spatel spatel 0 Feb 4 12:32 /tmp/incrontest-alpha
注意：在Ubuntu中,您需要在启动时激活inotify.请在Grub menu.lst文件中添加以下行：
kernel /boot/vmlinuz-2.6.26-1-686 root=/dev/sda1 ro inotify=yes
