Also the simple ls command defaultly sort the ouput by name even when skipping aliases \ls
To avoid this you can use a special option -f (may depends on your plateform) this will force ls to display all found entries WITHOUT ordering them ... which can be ... MUCH FASTER in some case.
That is why when used with wc -l , and especially for direcory containing numerous entries, the ls command should be used with such "nosort" option

I am trying to write a script that will look for a file in a directory, then remove it. I need it to loop until it has removed a certain number of files. Is it better to do a repeat or to list each file in a pattern? Files will be numbered like RAF.01.*, RAF.02.*, etc. Thanks, James (6 Replies)
