echo "option [-E|-e] enables full extended regexp support" >&2

echo "without [-E|-e] plain strings are looked for" >&2

return 1

\ps -eo 'user,pid,pcpu,command' w | head -n1

local ARG=''

if (( ${EXTENDED_REGEXP} == 0 ))

then

while (( ${#} > 0 ))

ARG="${1}"

shift 1

local LENGTH=$(expr length ${STRING})

local FIRSCHAR=$(echo $(expr substr ${STRING} 1 1))

local REST=$(echo $(expr substr ${STRING} 2 ${LENGTH}))

\ps -eo 'user,pid,pcpu,command' w | grep "[${FIRSCHAR}]${REST}"

Search for a process by name

Function that searchs for process by its name:

* Shows the Header for reference

* Hides the process 'grep' from the list

* Case sensitive

The typical problem with using "ps | grep" is that the grep process shows up the in the output.

The usual solution is to search for "[p]attern" instead of "pattern".

This function turns the parameter into just such a [p]attern.

${1:0:1} is the first character of $1

${1:1} is characters 2-end of $1

Monitor system load and print out top offending processes

This checks the system load every second and if it's over a certain threshold (.8 in this example), it spits out the date, system loads and top 4 processes sorted by CPU.

Additionally, the \a in the first echo creates an audible bell.

If you want to see your top ten cpu using processes from the browser (e.g. you don't want to ssh into your server all the time for checking system load) you can run this command and browse to the machines ip on port 8888. For example 192.168.0.100:8888

Find longest running non-root processes on a machine

If you have ever been trying to look for a list of processes based on their elapsed time you don't need to look any further.

This command lets you find the list of processes ordered in a reversed order (oldest at the top) that have been running for over an hour on your system. Any system processes are filtered out, leaving only user initiated ones in. I find it extremely useful for debugging and performance analysis.

Display CPU usage in percentage

Using the output of 'ps' to determine CPU usage is misleading, as the CPU column in 'ps' shows CPU usage per process over the entire lifetime of the process. In order to get *current* CPU usage (without scraping a top screen) you need to pull some numbers from /proc/stat. Here, we take two readings, once second apart, determine how much IDLE time was spent across all CPUs, divide by the number of CPUs, and then subtract from 100 to get non-idle time.

pgrep foo

sed puts "-p " in front and we pass a list to top:

top -p 11427 -p 12576 -p 12577

Like the original version except it does not include the parent apache process or the grep process and adds "sudo" so it can be run by user.

Hide the name of a process listed in the `ps` output

exec -a $NAME $COMMAND $ARGS

`your_cmd -erase_all_files` is the real process, but harmless-looking getty appears in the process table.

Never actually had a need to do this, but interesting nonetheless... Tested in bash, dash.

-a $NAME

"pass NAME as the zeroth argument to COMMAND", i.e. customise the name of the process (as commonly seen with `ps`)

Show WebSphere AppServer uid|pid|cell|node|jvms

Tested in bash on AIX & Linux, used for WAS versions 6.0 & up. Sorts by node name.

Useful when you have vertically-stacked instances of WAS/Portal. Cuts out all the classpath/optional parameter clutter that makes a simple "ps -ef | grep java" so difficult to sort through.
