当我在我的linux服务器上运行ps -aux命令时,我使用putty连接到它,很少有进程太长而不能适应我当前的窗口宽度。还有别的选择吗?

很抱歉我降级了,我觉得别人也不会觉得这个答案有用,所以我降级了。
这是你要的资料。

很可能您正在使用一个寻呼机,如less或most,因为ps aux的输出比满屏的要长。如果是这样,以下选项将导致(或强制)长行换行,而不是被截断。
ps aux | less -+S
ps aux | most -w
如果使用下列命令之一,将不会换行,但可以使用方向键或其他移动键向左或向右滚动。
ps aux | less -S # use arrow keys, or Esc-( and Esc-), or Alt-( and Alt-)
ps aux | most # use arrow keys, or < and > (Tab can also be used to scroll right)
对于more和pg,行总是被换行。
当ps aux在管道中使用时,w选项是不必要的,因为ps只在输出到终端时使用屏幕宽度。
使用auxww标志,您将在终端窗口和shell脚本中看到输出的完整路径。
darragh@darraghserver ~ $uname -a
SunOS darraghserver 5.10 Generic_142901-13 i86pc i386 i86pc
darragh@darraghserver ~ $which ps

darragh@darraghserver ~ $/usr/ucb/ps auxww | grep ps

darragh 13681 0.0 0.0 1420 852 pts/1 S 14:39:32 0:00 grep ps
Ps aux列出所有用户执行的所有进程。详情见man ps。ww标志设置无限宽度。
-w Wide output. Use this option twice for unlimited width.
w Wide output. Use this option twice for unlimited width.
我在下面的博客上找到了答案:

如果手动指定输出格式,还需要确保args选项位于输出字段列表的最后,否则它将被截断。
ps -A -o参数,pid,lstart给出

其他人提到的截断证据(个人例子)
foo=$(ps -p 689 -o command); echo "$foo"
COMMAND
/opt/conda/bin/python -m ipykernel_launcher -f /root/.local/share/jupyter/runtime/kernel-5732db1a-d484-4a58-9d67-de6ef5ac721b.json
^^在变量中捕获长输出
而不是
ps -p 689 -o command
COMMAND
/opt/conda/bin/python -m ipykernel_launcher -f /root/.local/share/jupyter/runtim
因为我试图从一个Docker jupyter笔记本,我需要运行这个当然爆炸..
!foo=$(ps -p 689 -o command); echo "$foo"
令人惊讶的是,jupyter笔记本甚至可以让你执行!但是很高兴能帮你找到那本占用了我所有内存的笔记本
