Determine what process is listening on a port on Solaris, without lsof

Can use lsof, but since it's not part of the base OS, it's not always available. Show Sample Output

for x in `ptree | awk '{print $1}'`; do pfiles $x | grep ${PORT} > /dev/null 2>&1; if [ x"$?" == "x0" ]; then ps -ef | grep $x | grep -v grep; fi; done 2> /dev/null

Join lines split with backslash at the end

recurisvely md5 all files in a tree

Found this little gem here: http://info.michael-simons.eu/2008/10/25/recursively-md5sum-all-files-in-a-directory-tree/

Search for a string inside all files in the current directory

options: -n line nbrs, -i ignore case, -s no "doesn't exist", -I ignore binary args: * for all files of current dir (not hidden), .[!.]* for all hidden files I don't include by default the -R (recursive) option, which is not always useful. You add it by hand when needed.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Do some learning...

no loop, only one call of grep, scrollable ("less is more", more or less...)

Empty a file
