  • Linux下如何查看进程准确启动时间

    ps:process status

    for pid in $(pgrep httpd); do echo -n "${pid} " ; ps -p ${pid} -o lstart | grep -v "START" ; done

    ps -eo pid,lstart,etime,cmd | grep nginx

    -e Display information about other users' processes, including those without controlling ter-
                 minals.
    -o Display information associated with the space or comma separated list of keywords speci-
                 fied.  Multiple keywords may also be given in the form of more than one -o option.  Key-
                 words may be appended with an equals (`=') sign and a string.  This causes the printed
                 header to use the specified string instead of the standard header.  If all keywords have
                 empty header texts, no header line is written.

           lstart      STARTED   time the command started.  See also bsdstart, start, start_time, and stime.
    
           etime       ELAPSED   elapsed time since the process was started, in the form [[DD-]hh:]mm:ss.
