我正在尝试使用python子进程运行此bash命令
find /Users/johndoe/sandbox -iname "*.py" | awk -F'/' '{ print $NF}'
输出:-
helld.xl.py
parse_maillog.py
replace_pattern.py
split_text_match.py
ssh_bad_login.py
这是我在python2.7中所做的事情,但是它给出了awk命令过滤器不起作用的输出
>>> p1=subprocess.Popen(["find","/Users/johndoe/sandbox","-iname","*.py"],stdout=subprocess.PIPE)
>>> p2=subprocess.Popen(['awk','-F"/"','" {print $NF} "'],stdin=p1.stdout,stdout=subprocess.PIPE)
>>>p2.communicate()
('/Users/johndoe/sandbox/argparse.py\n/Users/johndoe/sandbox/custom_logic_substitute.py\n/Users/johndoe/sandbox/finditer_html_parse.py\n/Users/johndoe/sandbox/finditer_simple.py\n/Users/johndoe/sandbox/group_regex.py\n/Users/johndoe/sandbox/helo.py\n/Users/johndoe/sandbox/newdir/helld.xl.py\n/Users/johndoe/sandbox/parse_maillog.py\n/Users/johndoe/sandbox/replace_pattern.py\n/Users/johndoe/sandbox/split_text_match.py\n/Users/johndoe/sandbox/ssh_bad_login.py\n', None)
我也可以通过单独使用p1来获得输出,如下所示,但是我无法在这里使用awk
list1=[]
result=p1.communicate()[0].split("\n")
for item in res:
a=item.rstrip('/').split('/')
list1.append(a[-1])
print list1
最佳答案
如果您没有使用shell = True进行任何保留,那么这应该是非常简单的解决方案
from subprocess import Popen
import subprocess
command='''
find /Users/johndoe/sandbox -iname "*.py" | awk -F'/' '{ print $NF}'
'''
process=Popen(command,shell=True,stdout=subprocess.PIPE)
result=process.communicate()
print result
