Linux ps (英文全拼:process status)命令用于显示当前进程的状态
通过ps --help a
查询ps的参数:
[root@localhost ~]# ps --help a
Usage:
ps [options]
Basic options:
-A, -e all processes
-a all with tty, except session leaders
a all with tty, including other users
-d all except session leaders
-N, --deselect negate selection
r only running processes
T all processes on this terminal
x processes without controlling ttys
Selection by list:
-C <command> command name
-G, --Group <GID> real group id or name
-g, --group <group> session or effective group name
-p, p, --pid <PID> process id
--ppid <PID> parent process id
-q, q, --quick-pid <PID>
process id (quick mode)
-s, --sid <session> session id
-t, t, --tty <tty> terminal
-u, U, --user <UID> effective user id or name
-U, --User <UID> real user id or name
The selection options take as their argument either:
a comma-separated list e.g. '-u root,nobody' or
a blank-separated list e.g. '-p 123 4567'
Output formats:
-F extra full
-f full-format, including command lines
f, --forest ascii art process tree
-H show process hierarchy
-j jobs format
j BSD job control format
-l long format
l BSD long format
-M, Z add security data (for SELinux)
-O <format> preloaded with default columns
O <format> as -O, with BSD personality
-o, o, --format <format>
user-defined format
s signal format
u user-oriented format
v virtual memory format
X register format
-y do not show flags, show rss vs. addr (used with -l)
--context display security context (for SELinux)
--headers repeat header lines, one per page
--no-headers do not print header at all
--cols, --columns, --width <num>
set screen width
--rows, --lines <num>
set screen height
Show threads:
H as if they were processes
-L possibly with LWP and NLWP columns
-m, m after processes
-T possibly with SPID column
Miscellaneous options:
-c show scheduling class with -l option
c show true command name
e show the environment after command
k, --sort specify sort order as: [+|-]key[,[+|-]key[,...]]
L show format specifiers
n display numeric uid and wchan
S, --cumulative include some dead child process data
-y do not show flags, show rss (only with -l)
-V, V, --version display version information and exit
-w, w unlimited output width
--help <simple|list|output|threads|misc|all>
display help and exit

使用ps axhw -o cmd
只输出Linux ps查询结果的CMD列,比如获取Jenkins容器进程中的CMD:
[root@localhost ~]# ps -ef | grep -v grep | grep jenkins.war
jenkins 2616 2520 1 4月24 ? 00:12:24 java -Duser.home=/var/jenkins_home -Djenkins.model.Jenkins.slaveAgentPort=50000 -jar /usr/share/jenkins/jenkins.war
[root@localhost ~]#
[root@localhost ~]# ps axhw -o cmd | grep -v grep | grep jenkins.war
java -Duser.home=/var/jenkins_home -Djenkins.model.Jenkins.slaveAgentPort=50000 -jar /usr/share/jenkins/jenkins.war
