How do I get the full width result for the *nix command "ps"?
I know we can specify something like --cols 1000 but is there anyway I can
the columns and just print out everything?
回答1:
Try ps -w -w aux. The -w option sets the output to wide, and doing it twice makes the width unlimited. The "aux" part makes it show more information, and is (afaik) pretty standard mode to use. This is of course platform-dependant, the above works with procps version 3.2.7 on Linux.
回答2:
Specify the w option twice, if you're using BSD-style ps. e.g., ps auwwx. A different set of options apply when using System V ps.

There are two different option syntaxes for ps; the standard POSIX one based on SysV, and the BSD one. GNU ps, as used on linux, supports both, which it can do because the POSIX options have dashes in front and the BSD ones don't, as well as some of it's own options in the normal GNU --long-option-name style.
Anyway, to get all processes in POSIX style is -e, in BSD it's ax (a includes other user's processes, x includes processes without a controlling terminal i.e. daemons).
There is no single option that will make it include all the columns. There are a huge number of possible columns. The POSIX options -f, -F and -L all cause it to show different sets of extra columns, as does the BSD option u (hence the "ps aux" mentioned in another answer is a very common command).
If you really want more columns than that you have to name explicitly which ones you want, using the -o (or o) option. See the man page for a list. There's about a hundred different names you can use, but some of them are duplicates, and others display the same info in different ways.
