我想从ls -1hl
命令中提取信息。
我必须在不同的远程服务器上运行此命令,并从每个远程服务器上获得不同类型的输出,因为其中一些是solaris,其中一些是GNU linux
这里是ls -1hl
命令的片段,我想格式化: -
ssh user@server 'ls -1hl /path/to/directory'
ls_command: -
-rw-r----- 1 root groupA 0 2014-08-04 10:42 a.log
-rw------- 1 root groupA 48132720 Aug 1 23:45 core
-rwxr-xr-x 1 root groupA 208 Mar 13 17:18 restart.sh
lrwxrwxrwx 1 root groupA 49 2014-06-06 09:32 MerSem -> ../combined_ABC/scripts
drwxrwxrwx 3 root groupA 1.0K Apr 22 16:12 logs
我想从上面的代码段中提取以下信息: -
第一行
permission = -rw-r-----
links = 1
owner = rooot
group = groupA
size = 0
date = 2014-08-04 10:42
File/Directory Name = a.log
我的代码: -
Final_list = []
result = ls_command.split('\n')
for line in result:
coldata = []
a = re.search(r"^(.+?)\s{1,3}.*$",line)
b = re.search(r"^.+?\s{1,3}(\d{1,5}).*$",line)
c = re.search(r"^.+?\s{1,3}\d{1,5}(.+?)\s{1,3}.*$",line)
d = re.search(r"^.+?\s{1,3}\d{1,5}.+?\s(.+?)\s{1,3}.*$",line)
e = re.search(r"^.+?\s{1,3}\d{1,5}.+?\s.+?\s{1,3}([0-9.A-Za-z]+?)\s{1,3}.*$",line)
f = re.search(r"^.+?\s{1,3}\d{1,5}.+?\s.+?\s{1,3}[0-9.A-Za-z]+?\s{1,3}(.+?)\s{1,3}.*$",line)
g = re.search(r"^.*\s{1,3}(.+)$",line)
if a:
permissions = a.group(1)
if b:
links = b.group(1)
if c:
owner = c.group(1)
if d:
group = d.group(1)
if e:
size = e.group(1)
if f:
date = f.group(1)
if g:
filename = g.group(1)
if a and b and c and d and e and f and g:
coldata.append(permissions)
coldata.append(links)
coldata.append(owner)
coldata.append(group)
coldata.append(size)
coldata.append(date)
coldata.append(filename)
Final_list.append(coldata)
但是这段代码不适用于我得到的那种日期。
Print Final_list
