If you are looking for things today it won't be as easy as ps helpfully, Not, doesn't add the Month and Date to the output for processes started today .

If for earleir than today than ps -ef |...

That's a tad difficult if there are more than five fields.

Not sure what your awk command is but awk '{OFS=","};{print $0 (or print $1,$3,$5 etc)}' myfile > myfile.csv will output the result...

God I wish I'd read this three days ago :)

Ta very useful.

That wasn't quite the answer but got me thinking thanks :)

for some reason , not sure why, the backticks in the variable creation were interfering with the sed. Removing the backticks and suddenly...

I'm creating a lot of test data for some performance testing coming up. The vendor product I used to create the file had a slight bug in it and got some times wrong so I decided to use sed to fix it....

I'm not entirely sure I understand the question but one way, fairly clunky but hey that's me all over :)

If the input is all single column without separators;
start=grep -ni '^test' | awk...

I use a combination of top , ptree and sar to look at CPU hogs.

Top provides the pids of CPU intensive processes which works well with ptree to work out what they are doing.

Sar, google for...

I'm sure a google for regexp and egrep would answer the question

But given Unix manuals tend to assume you know the answer already :-P

This works as sed does line by line so by chaining the commands it acts on each line in order....

If I understand your question correctly Echo is processing one line at a time so you are sorting one line then outputting it to a file which really has no effect with the sort.

Create the file...

I'm not quite sure what you're trying to do but your while loop is in the wrong place.

Code:
keepLooping=1
while (( keepLooping == 1 ))
do
ssh user@domain
echo a
if [ ?? ] ; then

Ah my bad I wasn't clear enough :)

with the -f limiting it to file names I get with the find , find $dir -type f -exec du -k {} \; 2>>/dev/null | sort -rn | head -${hd}

I'm not sure if I should start a new thread so if I'm posting inappropriately apologies.

Is there a way to get du -k * | sort -rn | head -11, which I prefer for some reason to the find above to...
