How to view a specific process in top
Are there any relatively strightforward options with top to track a specific process?
Ideally by identifying the process by a human readable value? e.g. chrome or java.
In other words, I want to view all the typical information top provides, but for the results to be filtered to the parameters provided i.e.. 'chrome' or 'java'
process top

top | grep chromeworked perfectly - thanks!

@Pandya - also, the process I was looking for only ran for a few seconds (node.js during an integration test) - which meant when I usedps -x | process_nameto get the PID, when I ran the process again the PID was different and therefore the original PID wouldn't identify it.

You can simply use grep:
NAME
grep, egrep, fgrep, rgrep - print lines matching a pattern
SYNOPSIS
grep [OPTIONS] PATTERN [FILE...]
grep [OPTIONS] [-e PATTERN | -f FILE] [FILE...]
DESCRIPTION
grep searches the named input FILEs (or standard input if no files are named, or if a single
hyphen-minus (-) is given as file name) for lines containing a match to the given PATTERN. By
default, grep prints the matching lines.
Run following command to get output which you want (ex-chrome):
top | grep chrome
Here we are using grep with pipelines | so top & grep run parallel ; top output given to grep (as input) and grep chrome filters matching lines chrome until top stopped.

top -p `pgrep "java"`gives me the following error in a bash shelltop: -p requires argument. top -ppgrep -d ',' "apache2"did work for me, but I didn't really understand what the command was doing - is it way of feeding in multiple arguments to top?

@loretoparisi that may be because the selector you are using matches multiple processes. See this answer for a command that works with one or more matching processes.

top -p `pgrep -d "," java`
Explanation:
top -p pid1,pid2: show multiple process information, the pid should be separated by,
pgrep -d "," java: print the pids of all java program, the pids are separated by a newline by default. use the-d ","to separate it by,as required by the top.
If you see error like top: -p argument missing, it means no java program is running, i.e. the pgrep has no output.

Prevent the error by checkingpgrep's exit code :pids="$(pgrep -d, java)" && top -p "$pids"

In OpenBSD top, just press g and enter the command name you'd like to filter on.
In top on e.g. Ubuntu, press o and enter e.g. COMMAND=chrome to only show entries from the COMMAND column that are equal to chrome.
On Linuxes that uses the same top implementation as Ubuntu, read the FILTERING in a Window section in the top manual.

Other good answers have been provided, but I made a script some time ago, which I named ptop, that serves me well:
#!/bin/sh
top -p $(pidof "$@" |sed s# #,#g) 2>/dev/null
if [ $? -ne 0 ]; then
echo No processes with the specified name(s) were found
fi
This supports multiple process names to be specified (like ptop bash chrome) and provides a nicer error message in case there is/are no processes with any of the specified names running.

If you want to stay in top and keep all other processes in view for context, you can press L to search for your process:
Locate string chrome
This will highlight any process with chrome in the name, and bring it into view. Use & to go to the next match.
You can press c to switch between showing the process name and the full command.

top -p `pgrep "java"`gives me the following error in a bash shelltop: -p requires argument. top -ppgrep -d ',' "apache2"did work for me, but I didn't really understand what the command was doing - is it way of feeding in multiple arguments to top?

@Ramesh you need to give thepidlist comma separated to work.

+1 This is the correct answer. "top | grep Chrome" is rather barbaric, because it greps-away ALL OF THE OUTPUT from top not matching "Chrome," losing stuff like the header and column labels. Using a subshell with the output from pgrep is a correct application of the unix philosophy.

@loretoparisi that may be because the selector you are using matches multiple processes. See this answer for a command that works with one or more matching processes.

top -p `pgrep -d "," java`
Explanation:
top -p pid1,pid2: show multiple process information, the pid should be separated by,
pgrep -d "," java: print the pids of all java program, the pids are separated by a newline by default. use the-d ","to separate it by,as required by the top.
If you see error like top: -p argument missing, it means no java program is running, i.e. the pgrep has no output.

In OpenBSD top, just press g and enter the command name you'd like to filter on.
In top on e.g. Ubuntu, press o and enter e.g. COMMAND=chrome to only show entries from the COMMAND column that are equal to chrome.
On Linuxes that uses the same top implementation as Ubuntu, read the FILTERING in a Window section in the top manual.

Other good answers have been provided, but I made a script some time ago, which I named ptop, that serves me well:
#!/bin/sh
top -p $(pidof "$@" |sed s# #,#g) 2>/dev/null
if [ $? -ne 0 ]; then
echo No processes with the specified name(s) were found
fi
This supports multiple process names to be specified (like ptop bash chrome) and provides a nicer error message in case there is/are no processes with any of the specified names running.

If you want to stay in top and keep all other processes in view for context, you can press L to search for your process:
Locate string chrome
This will highlight any process with chrome in the name, and bring it into view. Use & to go to the next match.
You can press c to switch between showing the process name and the full command.

top | grep chrome?– Pandya

you can also use
ps -x | chrometo get pid (let pid shown2034) and thentop | grep 2034– Pandya
Oct 31 '14 at 11:02
top | grep chromeworked perfectly - thanks!– Michael Coleman
Oct 31 '14 at 11:05
@Pandya - also, the process I was looking for only ran for a few seconds (node.js during an integration test) - which meant when I used
ps -x | process_nameto get the PID, when I ran the process again the PID was different and therefore the original PID wouldn't identify it.– Michael Coleman
