i got a question about bash and awk, so, i'm going to filter the processes list from ps aux then i did filtering by grep, then i filter it again using awk to display only the pid and the path of the process, then save it to the corresponding ${pid} and ${path} field. the question is, when i done filtering the results using awk, i'm going to save those results on ${pid} for pid numbers and ${path} for process's path, but i got no idea at all on doing that thing. if anyone here have a solution it would be very appreciated.
我有一个关于bash和awk的问题，所以，我要从ps aux过滤进程列表然后我用grep过滤，然后我再次使用awk过滤它来显示pid和进程的路径，然后将其保存到相应的$ {pid}和$ {path}字段。问题是，当我使用awk过滤结果时，我将把这些结果保存在$ {pid}的pid数字和$ {path}的进程路径上，但我完全不知道做那件事。如果有人在这里有一个解决方案，将非常感激。
Thanks
谢谢
EDIT: here is the code
编辑：这是代码
ps aux | grep 'firefox' | awk '{print $2 " " $11}'
then i don't know what to do to save the $2 content to ${pid} and $11 to ${path} and save those fields to the txt file again...
然后我不知道如何将$ 2内容保存到$ {pid}和$ 11到$ {path}并将这些字段再次保存到txt文件中...

If all else fail remember that you have the disk that you can use. Pipe the result to a file and then process the file using awk or cut two times to assign the fields to the corresponding variables.
如果所有其他方法都失败，请记住您拥有可以使用的磁盘。将结果传递给文件，然后使用awk处理文件或剪切两次以将字段分配给相应的变量。
For example:
例如：
$result > tmp
pid=`cat tmp | cut -f 1`
path=`cat tmp | cut -f 2`
rm tmp
#2
1
This should do it:
这应该这样做：
read pid path <<< $(ps aux | grep 'firefox' | awk '{print $2 " " $11}')
#3
0
use set :
使用集：
out=$(ps aux | grep 'nginx' | awk '{print $2 " " $11}' )
set $out
pid=$1
path=$2
echo $pid
echo $path
#4
0
awk_output=($(ps aux | awk '/firefox/{print $2, $11}'))
pid="${awk_output[0]}"
path="${awk_output[1]}"
If your paths can contain spaces you'll need a different solution involving setting IFS.
如果您的路径可以包含空格，则需要一个涉及设置IFS的不同解决方案。
