 Q: I would like to know if there are any program utilities like top that I can use to

extract each process uptime?

I can t find any info about the /proc/ directory that I can parse to extract the info. I

would be greatly appreciated if any of you can help. Thanks...

Answer: Well you seem to have answered the question yourself: you can use  ps  or

 top  command to get the information, but parsing their output can be tedious.

There *is* a man page "proc".

On Linux the files contain text so you can simply read /proc/pid/stat (or

/proc/self/stat) like any ordinary file and read the process times directly. The fields

are described on the man page.

On Linux and other Unix platforms you can use JNI to call getrusage() to get the

process times. This is probably the most portable way to do it.
