cat /proc/10993/root/run_command
/usr/sbin/libvirtd --listen(nova-libvirt)

모든 PID run_command를 얻고 싶습니다.

하지만 읽기에는 너무 혼란스럽습니다. 각 기록(각 파일의 내용)을 어떻게 별도의 줄에 넣을 수 있나요?

run_comand_content1
run_comand_content2
run_comand_content3

또는

run_comand_content1

run_comand_content2

run_comand_content3

답변1

루프에 넣을 수 있습니다.

/proc/[0-9]*의 경우
하다
    printf "${i}\t"
    cat${i}/root/run_command
    "\n" 인쇄
완벽한

답변2

당신은 그것을 사용할 수 있습니다 awk:

awk 'FNR==1{printf ""}1' */root/run_command

또는 ---줄바꿈으로 구분합니다.

awk 'FNR==1{print "---"}1' */root/run_command
awk 'FNR==1{printf "\n"}1' */root/run_command

여기를 보아라다음을 사용하는 것과 같은 추가 답변 sed:

sed -e '$s/$/\n/' -s */root/run_command
