Tools Unable to grep the process
I have user1 run a script called logginexpert.sh while has this line of code

Code:
sleep 888

I then login to another putty session with another user2 and try to grep for the logginexpert.sh process using

Code:
ps -ef | grep ex

Code:
SunOS mymac 5.11 11.2 sun4u sparc SUNW,SPARC-Enterprise

But, i dont get any results when i was expecting it to show the process logginexpert.sh that was started by user1.



Can you please help me fix this problem ?

Does it show up in the long list, when not grepping?

Not sure what long list is but i grep for the entire script name and it still does not showup in the results.

Code:
ps -ef | grep logginexpert.sh
No results Found.

I also tried

Code:
 ps -ef >/tmp/tmp.tmp
grep ex /tmp/tmp.tmp
No results Found.

Can you even SEE the process using ps -ef

Do not use more or grep. Why? If the path to the file is part of the ps display for
Code:
 logginexpert.sh

then it may include the entire path - which can exceed what ps will show - too many characters.

PS: on Solaris pgrep may be your better choice for this kind of thing.

location of logginexpert.sh is /tmp/logginexpert.sh

Code:
 ps -ef | pgrep /tmp/testbkpme.sh
No results Found.
ps -ef | pgrep bk
No results Found.

ps -ef also does not show /tmp/logginexpert.sh but I'm able to grep the process by the pid but not with the script name.

Putty Session 1:
Code:
/tmp/logginexpert.sh &
[1]     4627

Putty Session 2:
Code:
You have new mail in /var/mail/user2
ps -ef | grep 4627
    user1 4627 10477   0 13:54:09 pts/11      0:00 sleep 888
ps -ef | grep ex
    user2 5650 15730   0 13:54:27 pts/16      No results Found.

So definitely the process is running.

---------- Post updated at 03:12 PM ---------- Previous update was at 02:36 PM ----------

Also ps -ef does not show the name of the script but i see this sleep 888 in the results.

Can you please help sort this out ? i want to grep by name of the script not by its contents.

Display the processes of user1
Code:
ps -fu user1

If "sleep" is spawned by the script then look for its parent process (given in column 3).
Maybe your grep is forged?
Code:
/bin/ps -fu user1 | /bin/grep ex

grep can match its own argument in the ps list. pgrep avoids that.
Code:
pgrep -u user1 ex

Bug
The issue is not to do with different users or different putty session. Becoz i Cannot find i.e grep for the logginexpert.sh script with the same user in the same putty session.

Also,

Code:
  /bin/ps -fu | /bin/grep ex
  /bin/ps: option requires an argument – u
  
  pgrep -u user1  ex
  No results Found.

/bin/ps fu  | /bin/grep ex
/bin/ps: illegal option -- f

/bin/ps u   | /bin/grep bk
Result not Found.

Let me know what are we missing ?
