需要解析linux命令的输出

Question

我有linux命令下面的输出：

/auto/qalogs/branch_team_5.7/drt/hash_list/bk20170401/audit-gc.rb:11:{:component=>"Encryption", :params=>"-f /auto/qalogs/branch_team/drt/hash_list/enc_options_rkm_ekm.rb log_level=debug", :script=>"encryption/destroy.rb", :timeout=>10800, :skipcheckconnection=>1, :minlimitver=>"5.3.0.0"} 
/auto/qalogs/branch_team_5.7/drt/hash_list/bk20170401/encryption-audit-gc-part1.rb:11:#{:component=>"Encryption", :params=>"-f /auto/qalogs/branch_team/drt/hash_list/enc_options_rkm_ekm.rb log_level=debug", :script=>"encryption/destroy.rb", :timeout=>10800, :skipcheckconnection=>1, :minlimitver=>"5.3.0.0"} 
Binary file /auto/qalogs/branch_team_5.7/ert/hash_list/.encryption-audit-gc.rb.swp matches 
/auto/qalogs/branch_team_5.7/ert/hash_list/encryption-audit-gc.rb:11:{:component=>"Encryption", :params=>"-f /auto/qalogs/branch_team/drt/hash_list/enc_options_rkm_ekm.rb log_level=debug", :script=>"encryption/destroy.rb", :timeout=>7200, :skipcheckconnection=>1, :minlimitver=>"5.3.0.0"} 

我只需要过滤此散列文件：

{:component=>"Encryption", :params=>"-f /auto/qalogs/branch_team/drt/hash_list/enc_options_rkm_ekm.rb log_level=debug", :script=>"encryption/destroy.rb", :timeout=>7200, :skipcheckconnection=>1, :minlimitver=>"5.3.0.0"} 

，并写入到另一个文件。

我试过followng：

out=subprocess.getoutput('grep -rwn 
/auto/qalogs/branch_team_5.7/ert/hash_list/ -e '+alist[0]+'') 
print ("output of grep is", out) 
pattern=re.compile(r'(/auto/qalogs/branch_team_5.7/ert/hash_list/.*.rb:\d) 
(\:)(\{.*\})',out) 
print (pattern.groupobject(0)) 

我得到这个exception.How办呢？

Answer 1

这应该是一个简单的re问题。

import re 

command = 'grep -rwn /auto/qalogs/branch_team_5.7/ert/hash_list/ -e ' + alist[0] + '' 
filter = '/auto/qalogs/branch_team/drt/hash_list/enc_options_rkm_ekm.rb'  

log = subprocess.subprocess.getoutput(command) 

with open('output.txt', 'w+') as f: 
    for message in log: 
     if re.search(filter, message): 
      f.write(result) 

不幸的是，我没有更多的样本数据真正审查它！
