I am trying to execute command
ps-ef | grep java
The output of this command is getting curtailed and I am not able to understand which process is it actually. So is there any way I can get the complete output and not the curtailed output?
For example output I receive when I execute the above command:
root 14018 13922 0 Nov 23 ? 381:00 java -D[Standalone] -server -XX:+UseCompressedOops -d64 -Xms4096m -Xmx4096m -XX
Now from the above output I am unable to know which process is this.
ps -eo pid,user,comm | grep java

Mac OS X Unix 101 Byte-Sized Projects, curtail limits the size of a program's output and preserves the last X KB of output with the following command: run_program | curtail -s 1G Most Unix system commands take input from your terminal and send the resulting output back to your terminal. A command normally reads its input from the standard input, which happens to be your terminal by default. Similarly, a command normally writes its output to standard output, which is again your terminal by default. Output Redirection

Easy way to limit file size (stdout) on a shell script level?, The correct data output would validate the computer code. The program would run on a Windows platform and emulate a series of UNIX commands. During this period, I dramatically curtailed the orders processed at my business since it Here < command > is the Unix command that’s producing the output you would like to page through. As an example, suppose you have a directory listing that is too long to fit on one screen. You would enter the following command to pause after each page:
From Hi-Tech to Lo-Tech: A Woodworker's Journey, U.S. Army Mobility Equipment Research & Development Command graphics programs and acquisition of additional graphics output devices, acquisition of an access, installation of an UNIX based PLEXUS system with color video projector for which the operations of the Center would be impaired, curtailed, or halted. Redirecting command output as well as commands I have a Bourne Shell script that is normally run as a background job and redirects it's output to a file internally (using exec >>); I use "set -x" to capture each command which provides me with a nice shell execution log if it all goes to pieces.

Historical Review, This quick tutorial explains how to assign the output of a bash shell command to a variable under a Linux, macOS, *BSD, or Unix like operating If you put a command inside $(…) (dollar-parenthesis), its output is substituted into the command line. The output of the command is split into separate words at each whitespace block, and each word is treated as a wildcard pattern; unless you want this to happen, put double quotes around the command substitution: "$(…)" .
- You know the PID and PPID, so is it the trouble that there are too many not-very-interesting options to Java and that's preventing you from seeing the important options that really identify what it's doing? You can poke around the manual for
psto see if there's a way to get the full command line, but you may be out of luck there, too. You may have to poke around
/proc/14018to find out what the full command line is. At least, that would be the last resort on Linux. I'm not sure if the Solaris
/procfile system is as informative.
