Operating Systems HP-UX Getting the lines that contains a '/' N times(N given at runtime) Post 302840765 by bibou25 on Tuesday 6th of August 2013 12:06:15 PM

Getting the lines that contains a '/' N times(N given at runtime)

Hi all,

The task I have sounds easy enough but my solution seems too much complicated and I would like some ideas/feedback on how to achieve the same goal with a more elegant solution on HP-UX B.11.23 (a grep with a regexp would be nice, I did not manage to do a working one :/ )

Here is my problem, I have a list of dirname as input and I need to return only the ones that have the depth required (given at runtime)

How I have achieved this so far, please note that the "find . -type d" is just to give you a working example, input will be a flat file and nb_wanted will be set at runtime (here it is set to 2, +1 for the carriage return character):

Code:
find . -type d   | awk   -v nb_wanted=3 '{ whole_line=$0; cmd="echo \""$0"\" | sed \"s/[^\/]//g\" | wc -c " ; cmd|getline; nb_returned=$0; close(cmd); if (nb_returned==nb_wanted) print whole_line ; }'

This solution is pretty slow too :/ Any pointer to a more effective solution would be appreciated.

Matt
