Just throw it on cat  which line-wraps automatically  ps aux   cat

Using the auxww flags  you will see the full path to output in both your terminal window and from shell scripts   darragh darraghserver    uname -a SunOS darraghserver 5 10 Generic 142901-13 i86pc i386 i86pc  darragh darraghserver    which ps  usr bin ps lt br gt   darragh darraghserver     usr ucb ps auxww   grep ps darragh 13680  0 0  0 0 3872 3152 pts 1    O 14 39 32  0 00  usr ucb ps -auxww darragh 13681  0 0  0 0 1420  852 pts 1    S 14 39 32  0 00 grep ps   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

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

It is likely that you re using a pager such as less or most since the output of ps aux is longer than a screenful  If so  the following options will cause  or force  long lines to wrap instead of being truncated   ps aux   less - S  ps aux   most -w   If you use either of the following commands  lines won t be wrapped but you can use your arrow keys or other movement keys to scroll left and right   ps aux   less -S      use arrow keys  or Esc-  and Esc-   or Alt-  and Alt-    ps aux   most         use arrow keys  or  lt  and  gt   Tab can also be used to scroll right    Lines are always wrapped for more and pg   When ps aux is used in a pipe  the w option is unnecessary since ps only uses screen width when output is to the terminal

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 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

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

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   usr lib postgresql 9 5 bin 29900 Thu May 11 10 41 59 2017 postgres  checkpointer proc 29902 Thu May 11 10 41 59 2017 postgres  writer process    29903 Thu May 11 10 41 59 2017 postgres  wal writer proces 29904 Thu May 11 10 41 59 2017 postgres  autovacuum launch 29905 Thu May 11 10 41 59 2017 postgres  stats collector p 29906 Thu May 11 10 41 59 2017  kworker 2 0                30188 Fri May 12 09 20 17 2017  usr lib upower upowerd     30651 Mon May  8 09 57 58 2017  usr sbin apache2 -k start  31288 Fri May 12 07 35 01 2017  usr sbin apache2 -k start  31289 Fri May 12 07 35 01 2017  sbin rpc statd --no-notify 31635 Mon May  8 09 49 12 2017  sbin rpcbind -f -w         31637 Mon May  8 09 49 12 2017  nfsiod                     31645 Mon May  8 09 49 12 2017  kworker 1 0                31801 Fri May 12 09 49 15 2017  kworker u16 0              32658 Fri May 12 11 00 51 2017   but ps -A -o pid lstart args gets you the full command line   29900 Thu May 11 10 41 59 2017  usr lib postgresql 9 5 bin postgres -D  tmp 4493-d849-dc76-9215 -p 38103 29902 Thu May 11 10 41 59 2017 postgres  checkpointer process    29903 Thu May 11 10 41 59 2017 postgres  writer process    29904 Thu May 11 10 41 59 2017 postgres  wal writer process    29905 Thu May 11 10 41 59 2017 postgres  autovacuum launcher process    29906 Thu May 11 10 41 59 2017 postgres  stats collector process    30188 Fri May 12 09 20 17 2017  kworker 2 0  30651 Mon May  8 09 57 58 2017  usr lib upower upowerd 31288 Fri May 12 07 35 01 2017  usr sbin apache2 -k start 31289 Fri May 12 07 35 01 2017  usr sbin apache2 -k start 31635 Mon May  8 09 49 12 2017  sbin rpc statd --no-notify 31637 Mon May  8 09 49 12 2017  sbin rpcbind -f -w 31645 Mon May  8 09 49 12 2017  nfsiod  31801 Fri May 12 09 49 15 2017  kworker 1 0  32658 Fri May 12 11 00 51 2017  kworker u16 0

Passing it a few ws will ignore the display width

User · Answer

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
