SYNOPSIS
ps [−aA] [−defl] [−g grouplist] [−G grouplist]
[−n namelist] [−o format]... [−p proclist] [−t termlist]
[−u userlist] [−U userlist]
.ps參數：
−a Write information for all processes associated with termi‐ nals. Implementations may omit session leaders from this list. −A Write information for all processes. −d Write information for all processes, except session leaders. −e Write information for all processes. (Equivalent to −A.) −f Generate a full listing. (See the STDOUT section for the contents of a full listing.) −g grouplist Write information for processes whose session leaders are given in grouplist. The application shall ensure that the grouplist is a single argument in the form of a <blank> or <comma>-separated list. −G grouplist Write information for processes whose real group ID numbers are given in grouplist. The application shall ensure that the grouplist is a single argument in the form of a <blank> or <comma>-separated list. −l Generate a long listing. (See STDOUT for the contents of a long listing.) −n namelist Specify the name of an alternative system namelist file in place of the default. The name of the default file and the format of a namelist file are unspecified. −o format Write information according to the format specification given in format. This is fully described in the STDOUT section. Multiple −o options can be specified; the format specifica‐ tion shall be interpreted as the <space>-separated concate‐ nation of all the format option-arguments. −p proclist Write information for processes whose process ID numbers are given in proclist. The application shall ensure that the proclist is a single argument in the form of a <blank> or <comma>-separated list. −t termlist Write information for processes associated with terminals given in termlist. The application shall ensure that the termlist is a single argument in the form of a <blank> or <comma>-separated list. Terminal identifiers shall be given in an implementation-defined format. On XSI-conformant sys‐ tems, they shall be given in one of two forms: the device's filename (for example, tty04) or, if the device's filename starts with tty, just the identifier following the characters tty (for example, "04"). −u userlist Write information for processes whose user ID numbers or lo‐ gin names are given in userlist. The application shall en‐ sure that the userlist is a single argument in the form of a <blank> or <comma>-separated list. In the listing, the nu‐ merical user ID shall be written unless the −f option is used, in which case the login name shall be written. −U userlist Write information for processes whose real user ID numbers or login names are given in userlist. The application shall ensure that the userlist is a single argument in the form of a <blank> or <comma>-separated list. With the exception of −f, −l, −n namelist, and −o format, all of the options shown are used to select processes. If any are specified, the default list shall be ignored and ps shall select the processes repre‐ sented by the inclusive OR of all the selection-criteria options

參數-w顯示窗口和cygwin進程
.運行ps Nt:
nabaolong@DESKTOP-84KNVJ3 ~ $ ps Nt PID PPID PGID WINPID TTY UID STIME COMMAND 1514 1513 1514 3548 pty0 197609 10:51:46 /usr/bin/bash 1529 1514 1529 12268 pty0 197609 11:09:44 /usr/bin/ps 1513 1 1513 19000 ? 197609 10:51:45 /usr/bin/mintty
參數-N顯示所有的程序，除了執行ps指令終端機下的程序之外。
參數-t指定終端機編號，並列出屬於該終端機的程序的狀況。
.運行ps defl:
nabaolong@DESKTOP-84KNVJ3 ~ $ ps defl PID PPID PGID WINPID TTY UID STIME COMMAND 1514 1513 1514 3548 pty0 197609 10:51:46 /usr/bin/bash 1530 1514 1530 3924 pty0 197609 11:11:00 /usr/bin/ps 1513 1 1513 19000 ? 197609 10:51:45 /usr/bin/mintty
參數-d為所有流程編寫信息，會話負責人除外。
參數-l較詳細地顯示該PID的信息。
.解釋返回中的字段：
uid(user id)：用戶id；
pid(process id)：進程id;
ppid(parent process id)：父進程id；
c：cpu使用的資源百分比；
stime：系統啟動時間；
pgid(process group id)：進程組id號；
tty(teletype)：終端的次要裝置號碼；
time：使用的cpu時間；
cmd：所下達的指令。
4. 通過該實驗產生新的疑問及解答
1)安裝軟件時一開始網站打不開，就在一個app里下載了一個舊版本，但是安裝時就不行
解答：找到已經安裝好的同學要到了安裝包，順利的下載了軟件
2）用戶名更改時命令l和|未區分好耽誤了很多時間
解答：多次嘗試加外界求助完成了用戶名修改
