I used to use Linode. The basic, cheapest one is now $5 USD a month:

But I'm sure there are even cheaper services out there, for sure.

Also, one of our...

Congrats on starting to learn JS and JSON APIs.

Does your code work?

Hi.

Here are the important parts of a script that seems to do what you wish (including a sample data file). It runs twice, once considering the underscore as a separator, then as a character:
#...

How about, given your grep accepts "regular expression extensions" like \b that are not necessarily available in all systems / versions:

grep -o "\b[sS][^ ]*" <<< "String Filter increment. The...

If you are trying to learn what can be done by grep ( because others would suggest use sed or awk...)
As I only have my mac laptop at the moment this is what I would do if were to use only grep:...

Dont use view... use cat instead...
but you could also:
grep "WARNING: " datasource.log

I am not sure but probably the various nested subshells are at fault. As Corona688 mentioned. I only saw your second version and did not realise in your first posting the "cd" was within the...

Your line:

logfile=`cd '/opt/product/apachetomcat/8080/8.5.5_8080/apache-tomcat-8.5.5/logs'` was nonsensical, as `` captures the output of a command and the cd command outputs nothing. So you...

Hi try:
logdir=/opt/product/apachetomcat/8080/8.5.5_8080/apache-tomcat-8.5.5/logs
cd "$logdir"

The following is the total amount of the top process plus its children plus its children-children plus...(all down the tree)
pstree -ac 9059 | wc -l

somewhat rough - for a given data sample - can probably be generalized:

pstree 9059 | awk -F'[-*]' '{print $3+$5}'

Does the apmccctrl.sh script start up the processes in the background? Can you share it (wrapped in CODE tags, of course)

Some indenting of your code would help the clarity of the process,...

We are subtracting field 7 ("available") from field 2 ("total"), as you do in your script above.
The OFMT is an awk variable defining the "format for printing numbers; initially = "%.6g"." (man...

In principle, yes. However, inside the ((...)) ("arithmetic expansion") you don't need the $ , see e.g. man bash.

But, you have picked the perfect line to illustrate what I was talking about:

Mabe the process name is too long for pgrep then use pgrep -f (run on the full args).

Hello simpsa27,

Your Welcome, happy to help, could you please go through following and let me know if this helps you.

awk --re-interval '/Primary-login/{ ...

Hello simpsa27,

Could you please try following and let me know if this helps you.

You could put any string there in place of login above, let me know if you...

Hello simpsa27,

Could you please try following and let me know if this helps you.

awk --re-interval '/Primary-login/{val=$9} END{match(val,/-[0-9]{10}/);print substr(val,RSTART+1,RLENGTH-1)}' ...

Basically the [...]construct matches any of the characters inside the square brackets. So if you wanted to match any time from 03:00 to 06:59 inclusive the following expression will match:...

There's your problem! No century. Try
$ sed -n '\^4/26/17 0[89]:[0-9][0-9]^p' IntroscopeEPA.log
instead!

Basically as you are using the slash for searching sed stops at the second slash. By prefixing the slashes in between with backslahes, they won't be interpreted by sed as the end of the search...

You have two main choices:-

Adding another line into your SQL, you could tryselect count(*), state from pg_stat_activity group by state;

Hi,

I've had to hard-code the variables in this example of course, but something like this should work.
