1、前言
Pstree- List processes as a tree，當我們打 ps 會列出執行序 (Processes) 因此 pstree 我們可以顧明思義的了解其功能為將 ps 列成樹狀 (tree)，可看到 PID、user、COMMAND 以便讓我們更了解執行序的樹狀結構，以補充 ps 資訊的不足。文章目錄

221 Goodbye.步驟2.安裝 pstree 套件
執行如下指令以安裝 pstree 套件。# cd /export/home/weithenn/software //切換到套件下載路徑
# gzip -d pstree-2.27-sol10-x86-local.gz //解壓縮 pstree 套件
# pkgadd -d pstree-2.27-sol10-x86-local //安裝 pstree 套件
The following packages are available:
1 SMCpstree pstree
(x86) 2.27
Select package(s) you wish to process (or 'all' to process all packages). (default: all) ?,??,q: //預設 all 全裝
Processing package instance <SMCpstree> from </export/home/weithenn/software/pstree-2.27-sol10-x86-local>

安裝完畢後，便可以操作 pstree。# pstree

剛才去找了一下 sunfreeware 也有 Taiwan Anonymous FTP Mirror Sites 這樣就不用每次抓套件就出國比賽了。進入後路徑都在 freeware/i386/10 下。1.列出安裝套件的概要資訊
