get string on command ps -edf | grep -i mongod

This will get it....

ps -edf | grep -i mongod | sed -e 's/  */ /g' | cut -d' ' -f 8 | cut -d'/' -f 5  | cut -d'-' -f 4,5

Select allOpen in new window

sed with reduce all multiple spaces to one space.
then cut (space) will get the program part,
then cut (/) will get the directory part and
then cut (-) get the last elements

That seems to work, noci

But what would be wrong with reducing your one-liner to this?:

ps -edf | grep mongod | cut -d/ -f5 | cut -d- -f4,5

Select allOpen in new window

ps -edf | sed -ne  's:.*mongodb-[ ^-][ ^-]*-\([ ^/-][ ^/-]*\).*:\1:p'

or the more efficient

pgrep mongodb ...

Hi skullnobrains,

I've just tried this solution of yours:
    ps -edf | sed -ne  's:.*mongodb-[ ^-][ ^-]*-\([ ^/-][ ^/-]*\).*:\1:p'
I get no output from it.  Check this out:

$ cat ps-edf.txt
mongod    2530     1  3 Jan23 ?        23:08:29 /var/lib/mongodb-mms-automation/mongodb-linux-x86_64-3.2.6-ent/bin/mongod -f /var/lib/mongodb/automation-mongod.conf
$ sed -ne 's:.*mongodb-[ ^-][ ^-]*-\([ ^/-][ ^/-]*\).*:\1:p' ps-edf.txt
$
Does it work for you?  If so, please demonstrate.

And please expand on what you mean by this:
    pgrep mongodb ...
particularly the "..." part, which is a bit (or even a byte) ambiguous.

The sed statement reduces possibly multuple space to one so it is  deterministic to split in columns correctly.
Then split  out the program name using the spaces
then split out the directory

So a more top/down splitting.    think about using a username with a - in it.

In this case it will work, until you change to a date formatting that includes a /... (that might also throw off spaces counting btw)...

Hi noci,

When you say:
   "In this case it will work..."
about the sed statement, did you try it?  is it working for you?  As you can see by my last post, it ain't working for me.

gladly

$ echo 'mongod    2530     1  3 Jan23 ?        23:08:29 /var/lib/mongodb-mms-automation/mongodb-linux-x86_64-3.2.6-ent/bin/mongod -f /var/lib/mongodb/automation-mongod.conf' > /tmp/edf
$ cat /tmp/edf | sed -ne 's:.*mongodb-[ ^-][ ^-]*-\([ ^/-][ ^/-]*\).*:\1:p'
$ cat /tmp/edf | sed -ne 's:.*mongodb-[^-][^-]*-\([^/-][^/-]*\).*:\1:p'
x86_64

my second attempt works because i removed the extra spaces which got somehow added before each "^" character

"pgrep mongodb" would be a replacement for "ps -edf" that only outputs the mongodb process.
you may need to adjust the command.
it does not make much of a difference but will be a little more efficient if you have lots of process running

ps -edf | grep -i mongod      == replaced with echo ........

$ echo 'mongod    2530     1  3 Jan23 ?        23:08:29 /var/lib/mongodb-mms-automation/mongodb-linux-x86_64-3.2.6-ent/bin/mongod -f /var/lib/mongodb/automation-mongod.conf'| sed -e 's/  */ /g' | cut -d' ' -f 8 | cut -d'/' -f 5  | cut -d'-' -f 4,5
3.2.6-ent
$ 

Select allOpen in new window

So it works... please check space count s/  */ /g     reads: es slash space space star slash space slash gee  
space space star   -     one space to anchor, and zero or more spaces to replace...,    ==> every string of 1 or more space is repalce by one space.
When typeing one space it will not work, also with three spaces it will not work.
A better approach would be space space + (  +)  where 2 or more spaces will be replaced with a single space, leaving all single spaces alone.
alas not all sed implementation allow for a + in the the Regular Expression.

Hi skullnobrains,
$ cat /tmp/edf | sed -ne 's:.*mongodb-[^-][^-]*-\([^/-][^/-]*\).*:\1:p'
x86_64
my second attempt works because i removed the extra spaces which got somehow added before each "^" character
I don't think your second attempt works, because bibi92 asked for "3.2.6-ent", not "x86_64".
Looking forward to your 3rd attempt.  8)

Hi noci,
I'm still waiting for your answer to my question "what would be wrong with reducing your one-liner to this?:"

ps -edf | grep '^mongod ' | cut -d/ -f5 | cut -d- -f4,5

Select allOpen in new window

(Note: I've now added '^' above to ensure the match is at the start of the line only, (and presumably speed up the matching process minutely), and quotes with a space after to prevent matches with (admittedly unlikely) usernames like 'mongod2'.)

@tel2

lol, here is the third

$ cat /tmp/edf | sed -ne 's:.*mongodb-[^-][^-]*-[^-][^-]*-\([^/-][^/-]*\).*:\1:p'
3.2.6

Select allOpen in new window

anyway, that's just for the sake of oversimplifying. i marked @noci's initial answer as the solution

As much as I hate to sound like a broken record, skullnobrains...
I don't think your third attempt works, because bibi92 asked for "3.2.6-ent", not "3.2.6".  But you're getting closer.
Looking forward to your 4th attempt.  8)

lol, no, i see no point in the game. i merely wanted to demonstrate it is feasible with a single sed. i did my last attempt around 4AM... and i'm prtty sure the author does no really care and every single other contributor in this thread can do the exercise easily... s:.*mongodb-[^-][^-]*-[^-][^-]*-\([^/][^/]*\).*:\1:p

Well done, skullnobrains.
It seems you do your best work when you see no point in it.   8)

hopefully, my job is often pointless (　^ω^）

Hello,

Exactly, sorry for the delay, I search to get 3.2.6-ent.

Thank you

Best regards

Hello

ps -edf | grep '^mongod ' | cut -d/ -f5 | cut -d- -f4,5
agent -f
3.2.6-ent
agent-6.1.2.402

I need to get only 3.2.6-ent

Thank you

Best regards

Hi bibi92,

Please provide the output of "ps -edf" which returns those results from the command you ran.  Then we can find out what's going wrong and try to fix it.

Hello

ps -edf | grep '^mongod ' | cut -d/ -f5 | cut -d- -f4,5 returns :

 agent -f
 3.2.6-ent
 agent-6.1.2.402

 I need to get only 3.2.6-ent

 Thank you

 Best regards

Hi bibi92,

You already showed us what
    ps -edf | grep '^mongod ' | cut -d/ -f5 | cut -d- -f4,5
returns, but I did not ask for that.  I want the output from this:
    ps -edf
Then we can find out what's going wrong and try to fix it.

Hello,

Hi bibi92,

Your original post gave us this data to extract "3.2.6-ent" from:

mongod    2530     1  3 Jan23 ?        23:08:29 /var/lib/mongodb-mms-automation/mongodb-linux-x86_64-3.2.6-ent/bin/mongod -f /var/lib/mongodb/automation-mongod.conf

The only lines starting with "mongod" in your last post are these:

mongod    7481     1  0 Mar16 ?        01:20:53 /opt/mongodb-mms-automation/bin/
mongod    7651     1  2 Mar16 ?        03:15:06 /var/lib/mongodb-mms-automation/
mongod    7725     1  0 Mar16 ?        00:14:18 /var/lib/mongodb-mms-automation/

How are we supposed to find "3.2.6-ent" in those?

Seems a non wrapped window cutting off the beyond the right edge..., so that info is lost...
Now why doesn't this work:

ps -edf | grep -i mongod | sed -e 's/  */ /g' | cut -d' ' -f 8 | cut -d'/' -f 5  | cut -d'-' -f 4,5

Select allOpen in new window

Hello,

$ ps -edf | grep -i mongod | sed -e 's/  */ /g' |  cut -d' ' -f 8 | cut -d'/' -f 5  | cut -d'-' -f 4,5
agent
3.2.6-ent
agent-6.1.2.402
grep

Only 3.2.6-ent must be returned.

Thank you

Best regards

I'm still waiting for your answer to the question at the bottom of my last post, bibi92.
Please provide data which contains the stuff you're wanting us to extract for you.
