Very Computer

This is the problem:
when I execute the command
ps -efx | grep mycommand
I would like the result of the command column was complete.
Instead the result is all the command but the last char.
For example if I execute
tail -f myfile_1234_6789
the result of
ps -efx | grep tail | grep -v grep
for the command column is
tail -f mifile_1234_678

I don't know!
Somebody can help me.
I need to read all the command line I executed.

Bye
Luca

You need the -w switch, I think

Or, for really long commands, -ww.

This is likely very dependent on you opsystem plus the code in ps.
Some versions of ps look at a proctable structure that holds only
a maximum of 30 or 60 characters of the actual command line. The
command line may be thousands to megs of characters (hint: echo *
in a massive directory) and it would be impractical to keep the
entire line in a kernel proctable structure.

Some versions of ps don't have -x as an option at all (all versions
of HP-UX except the latest 11.11) and other versions do not have -w
as an option.
