리눅스 ps-ef.... UID중복

글쓴이: please63 / 작성시간: 토, 2019/05/11 - 2:26오전

1.리눅스 vim에서 출력후에 빈줄도 출력하고싶은데 방법이 있을까요? 10줄이 있으면 root,hostname이 UID라면 나머지 8줄은 \n으로 출력하고 싶습니다.

2.리눅스 ps -ef중복아닌 것을 하다보니 UID 와 같이 목록?이 출력이 됩니다. 이것을 빼는 방법이 있나요?

awk를 이용해서 뽑아내고있는데 맞는방법일까요

Traceback (most recent call

글쓴이: 황병희 / 작성시간: 일, 2019/05/12 - 10:33오후

Traceback (most recent call last):
  File "./33.py", line 8, in <module>
    p = subprocess.Popen(["ps", "-ef"], stdout=subprocess.PIPE, text=True)
TypeError: __init__() got an unexpected keyword argument 'text'

파이썬 3.6.7 환경에서 위와 같은 에러가 나서..
"text=True" 를 "universal_newlines=True" 으로 코드 수정해서 실행시키니 성공했습니다.
기록을 위하야 댓글 남깁니다.

Changed in version 3.7: Added the text parameter, as a more understandable alias of universal_newlines. Added the capture_output parameter.

CMD 열이 사실 대게 긴줄도 있습니다.
그래서 코드를 좀 더 보완했씁니다.

 
...snip...
 
v7 = []
for x in lines:
    v7.append(x.split()[7:]) # [7] 에서 [7:] 로 변경합니다.
CMD = v7
 
for x,y,z in zip(UID,PID,CMD):
    print(f'{x:10} {y:7} {" ".join(z)[:43]}') # z 항목을 43자까지만 출력시키도록...
 
...snip...

# 변경된 코드 테스트 결과입니다. 
# 우분투 18.04, 파이썬 3.6.7
