Linux命令找出正在运行的进程的“计数”？

Question

There are 3 processes. I have to find the "count" of running process in current directory.

# named ../sample

And:

[root@sp3 sample]# ps -eaf|grep perl
root     14104     1 58 08:39 ?        03:31:34 perl example1.pl
root     17441     1 41 09:09 ?        02:17:24 perl example2.pl
root     24543     1  0 Jul05 ?        00:00:00 perl sample.pl
[root@sp3 sample]#

The result I have to return is 3.

I have currently in sample directory and I have to count the number of process in same directory

Please post any solution.

Answer 1

Try

LOCAL_PWD = pwd
ps -auxeaf| grep $LOCAL_PWD| wc -l

wc -l counts lines

Regarding how to show full path of processes please take a look at here

Answer 2

This really isn't the right place for this (there's a linux part of stackexchange). But you can use wc to count lines in any output, so pipe your command to it like this: ps -eaf | grep perl | wc -l ps -eaf | grep perl | wc -l ps -eaf | grep perl | wc -l . By the way I'd also recommend making the grep command not match itself by doing grep [p]erl (putting []'s around any one character will still match only 'perl', but the grep command no longer has 'perl' in it).

In case it's of use to you I've put together a script like I mentioned in the comment below.

total=0
for file in $(find -executable -type f) ; do
    echo "Checking $file:"
    count=$(ps -ef | awk '{print $8}' | grep "^.*/*${file##*/}$" | wc -l)
    echo "$count processes found."
    total=$(($total + $count))
done
echo $total

Simple: ps -eaf | grep perl | grep -v grep | wc -l

Answer 4

I know the topic is old, but there is no solution for this Problem.

Solution 1

ps ax |egrep "^/your/path/to/Script" |wc -l

• ps ax = Processlist

• egrep = gets all processes from the list that start with the specified path. You need to start your Perl scripts with Path/Script.pl and not like./script. ^ = Multiline - You can also use normal grep "/your/path/to/script"

• wc -l = Count all results

• Output = 3

Solution 2

Name you scripts with a specific identifier and grep for it like:

script_example_ ident .pl

ps ax |grep "ident" |wc -l

Answer 5

If by running you mean "queued for execution":

ps ax -o stat,args |grep '^R'|wc -l
