/etc/exclude.rootvg中附件中的两种表示有什么区别

 -e
            Excludes files listed in the /etc/exclude.rootvg file from being backed up.
             The rules for exclusion follow the pattern matching rules of the grep command.

            If you want to exclude certain files from the backup, create the /etc/exclude.rootvg file, with an ASCII editor, and enter the patterns of file names that you do not want
            included in your system backup image. The patterns in this file are input to the pattern matching conventions of the grep command to determine which files will be excluded from
            the backup. If you want to exclude files listed in the /etc/exclude.rootvg file, select the Exclude Files field and press the Tab key once to change the default value to yes.

            For example:
              1    To exclude all the contents of the directory called scratch, edit the exclude file to read as follows:

                        /scratch/
              2    To exclude the contents of the directory called /tmp, and avoid excluding any other directories that have /tmp in the path name, edit the exclude file to read as follows:

                        ^./tmp/
            All files are backed up relative to . (current working directory). To exclude any file or directory for which it is important to have the search match the string at the
            beginning of the line, use the ^ (caret character) as the first character in the search string, followed by . (dot character), followed by the filename or directory to be
            excluded.

我的理解是加“^.”的话是只排除/directory/单个目录下的文件 但不包含目录
不加"^."的话是排除所有路径包含/directory/的文件和目录收起

./tmp是表示你在敲smit mksysb目录时的目录下有个tmp目录过虑掉，
/tmp就3楼兄弟CJ_ane所说的一样了。收起

mksysb是以实际的/作为当前工作目录.的，所以所有要备份的文件和目录都是以./为开头，^./tmp就是实际的/tmp，而^/tmp永远不会被匹配。但/tmp可以被匹配，比如/app/tmp收起

我问的是这个./tmp 和/tmp有什么区别（在/etc/exclude.rootvg中）收起

回复 5# wlcg99999
这个我就不知道了..收起

^在正则表达式中表示行首，所以能理解了吧收起

不能沉，顶起~收起

非常感谢CJ_ane，但是我给的目录前面有点，例如./tmp 和/tmp有什么区别（在/etc/exclude.rootvg中）收起

回复 3# CJ_ane

重新看了一遍，之前的理解有点问题，应该是这样的

/directory/ 是排除所有包含"direcotry"的目录,以及目录下的文件,举个例子:
1./direcotry/xxxx/xxx/xx 会被排除
2./xxxx/xxxx/directory/xx 会被排除

^./directory 是排除"/direcotry/"目录下的所有文件(use the ^ (caret character) as the first character in the search string)
1./direcotry/xxx/xxx/xxx 会被排除
2./xxx/direcotry/xxx/xxx 不会被排除收起

用第一个就对了。固体为啥。忘记了。:lol收起
