4035 That means I'm running ps over 4000 times! It takes nearly a minute to run. . My first thought was trawling through /proc, looking at the exe link, but that requires root privs for root processes. .ps -p $(find /proc -path /proc/\*/exe -maxdepth 2 -printf "%p %l\n" 2> /dev/null | awk -F/ '($5$6 ~ "usrs*bin") { print $3; }' | paste -s -d,)
It looks in /proc for the 'exe' symlinks to the commands; it filters out the exe locations; it joins them up and gives them to 'ps -p' . *Very* ugly, but it does run instantly!
