when I run ps -aux command on my linux server, to which I connected using putty, few processes are too long to fit in my current window width. Is there an alternative?

I am sorry for downgrading,I thought others won't find the answer useful too, so I downgraded.
Here is the info you asked for.

Just throw it on cat, which line-wraps automatically
ps aux | cat
If you grep the command that you are looking for with a pipe from ps aux, it will wrap the text automatically. I used a lot of the other answers on here, but sometimes if you are looking for something specific, it is nice to just use grep and you know that it will wrap lines.
For instance ps aux | grep ffmpeg .
Passing it a few ws will ignore the display width.
Using the auxww flags, you will see the full path to output in both your terminal window and from shell scripts.

ps aux lists all processes executed by all users. See man ps for details. The ww flag sets unlimited width.
-w Wide output. Use this option twice for unlimited width.
w Wide output. Use this option twice for unlimited width.
I found the answer on the following blog:
http://www.snowfrog.net/2010/06/10/solaris-ps-output-truncated-at-80-columns/
Sorry to be late to the party but just found this solution to the problem.
The lines are truncated because ps insists on using the value of $COLUMNS, even if the output is not the screen at that moment. Which is a bug, IMHO. But easy to work around, just make ps think you have a superwide screen, i.e. set COLUMNS high for the duration of the ps command. An example:
$ ps -edalf # truncates lines to screen width
$ COLUMNS=1000 ps -edalf # wraps lines regardless of screen width
I hope this is still useful to someone. All the other ideas seemed much too complicated :)
If you are specifying the output format manually you also need to make sure the args option is last in the list of output fields, otherwise it will be truncated.
ps -A -o args,pid,lstart gives

Evidence for truncation mentioned by others, (a personal example)
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
That ^^ captures that long output in a variable As opposed to
ps -p 689 -o command
COMMAND
/opt/conda/bin/python -m ipykernel_launcher -f /root/.local/share/jupyter/runtim
Since I was trying this from a Docker jupyter notebook, I needed to run this with the bang of course ..
!foo=$(ps -p 689 -o command); echo "$foo"
Surprisingly jupyter notebooks let you execute even that! But glad to help find the offending notebook taking up all my memory =D
you can set output format,eg to see only the command and the process id.
ps -eo pid,args
see the man page of ps for more output format. alternatively, you can use the -w or --width n options.
If all else fails, here's another workaround, (just to see your long cmds)
awk '{ split(FILENAME,f,"/") ; printf "%s: %s\n", f[3],$0 }' /proc/[0-9]*/cmdline
I found this answer which is what nailed it for me as none of the above answers worked
https://unix.stackexchange.com/questions/91561/ps-full-command-is-too-long
Basically, the kernel is limiting my cmd line.
If none of the solutions above work, the output of ps isn't your problem. Maybe you need to set putty to wrap long lines?
Otherwise, we need more information.
simple and perfect:
ps -efww
won't truncate line
