SYNOPSIS
ps [−aA] [−defl] [−g grouplist] [−G grouplist]
[−n namelist] [−o format]... [−p proclist] [−t termlist]
[−u userlist] [−U userlist]
.ps参数：
−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

4. 通过该实验产生新的疑问及解答
1)安装软件时一开始网站打不开，就在一个app里下载了一个旧版本，但是安装时就不行
解答：找到已经安装好的同学要到了安装包，顺利的下载了软件
2）用户名更改时命令l和|未区分好耽误了很多时间
解答：多次尝试加外界求助完成了用户名修改
