/proc directory script

I'm looking for a ruby script that accesses the /proc directory and saves the process ID and command line (cmdline) information 开发者_如何学Goin a file.

you may want to call ps instead of going to /proc.

cmd=`ps -eo pid,cmd`
o = File.open("output","w")
o.write(cmd)
o.close

you can also run below one liner bash script and redirect its output anywhere, as well as choose required argument option for head command.

ls -alR /proc/$(ls /proc/ |grep -i '[0-9]'|sort -n|head ) > /proc_open_files
