Version checking
Hi everyone,

I have binary file that call “app”, this file must be bind with “config file” to run.

problem is I have 10 different version of “app”, in different path with different “config file”!

This command show version of “app”:
Code:
root ~: /home/user1/app -version
2.7

The only way that i can get path of executable file and related config file is to run below command:

Code:
root ~: ps aux | grep app
/home/user1/app    bind          /home/user1/config1
/usr/app                   bind         /home/user5/config2
/tool/app                  bind         /opt/config3

...

Now I want to get list of version of each “app” that bind with config files, something like this:

1. config1 2.7
2. config2 4.9
3. config3 1.2

Any idea?

Maybe you can use symbolic links to help you solve this problem?

/home/user1/app    bind          /home/user1/config1
/usr/app                   bind         /home/user5/config2
/tool/app                  bind         /opt/config3

...
First off: what a mess! My suggestion is to standardise these app versions first: create a directory for every version and put respective version plus its config file there. Something like this:

Code:
/opt/myapp/
            .../version1/
            .../version1/app
            .../version1/config
            .../version2/
            .../version2/app
            .../version2/config

To have a path like /tool is already questionable but to put an application there and its config into /opt is a sure-fire recipe for disaster. It may be a lot of work but you should clean that up as soon as possible.

If you have one config for several versions create one (maybe somewhere else) and use symbolic links like Neo suggested to represent them at the respective directory. Something like:

Code:
/opt/myapp/
            .../configs/
            .../configs/version1-3
            .../configs/version4-6
            .../version1/
            .../version1/app
            .../version1/config -> /opt/myapp/configs/version1-3
            .../version2/
            .../version2/app
            .../version2/config -> /opt/myapp/configs/version1-3
...
            .../version4/
            .../version4/app
            .../version4/config -> /opt/myapp/configs/version4-6

The application would still address these as file "config" in the same directory as the application.

I hope this helps.

I need result export in text file not rename directory.

------ Post updated at 06:56 AM ------

I can't change location of files because they are running and I can't kill them.
I want to export result in text file , and don't want to create symbolic link or rename directory.

The following post-processes the ps output
Code:
#!/bin/sh
cnt=0
ps -eo args |
while read prog args
do
  case $prog in
  (*app);;
  (*)
    continue;;
  esac
  ver=$("$prog" -version </dev/null)
  echo "$((cnt+=1)) $prog $ver $args"
done
