Yes exactly, I did a simple "ls -d" without any dir-name which resulted in a neocortex getting caught in a endless loop producing errors.... > > Then, when wanting ls only to plot the names > > of the subdirectories in the current directory, > > I key "ls -F|grep" or "ls -p|grep". > > Is this the only way, Have I written this? - again one of my bad habits to skip/mangle my own thoughts. What I had used was "ls -F|grep /" or "ls -p|grep /" but found it rather silly because quite complicated for a simple wish. > You probably want something like: > ls -l | grep '^d' This is what perl users usually recommend :^) ? > > and why do the -p and -F options do not seem to differ in any way? > > They differ slightly. -F appends a * to executable files, while -p > doesn't. Again my "mangle" problem. Reading this I remembered the paragraph in the info. Too much coffee on that day... Thanks to Bob for the very helpful url too - puh what a awfull lot to read....
