2.6.11 file.file_exists

判断指定文件是否存在

[root@master ~]# salt '*' cmd.run 'ls -l /root/'
192.168.69.202:
    total 12
    -rw-r--r--. 1 root root   22 Feb 23 16:51 a
    drwxr-xr-x. 4 root root  165 Feb 19 09:20 abc

[root@master ~]# salt '*' file.file_exists /root/a
192.168.69.202:
    True
[root@master ~]# salt '*' file.file_exists /root/abc
192.168.69.202:
    False   //返回False是因为abc是目录而非文件

2.6.12 file.find

类似 find 命令并返回符合指定条件的路径列表

The options include match criteria:

name    = path-glob                 # case sensitive
iname   = path-glob                 # case insensitive
regex   = path-regex                # case sensitive
iregex  = path-regex                # case insensitive
type    = file-types                # match any listed type
user    = users                     # match any listed user
group   = groups                    # match any listed group
size    = [+-]number[size-unit]     # default unit = byte
mtime   = interval                  # modified since date
grep    = regex                     # search file contents

and/or actions:

delete [= file-types]               # default type = 'f'
exec    = command [arg ...]         # where {} is replaced by pathname
print  [= print-opts]
and/or depth criteria:

maxdepth = maximum depth to transverse in path
mindepth = minimum depth to transverse before checking files or directories

The default action is print=path

path-glob:

*                = match zero or more chars
?                = match any char
[abc]            = match a, b, or c
[!abc] or [^abc] = match anything except a, b, and c
[x-y]            = match chars x through y
[!x-y] or [^x-y] = match anything except chars x through y
{a,b,c}          = match a or b or c
