1. copy/remove folders on a remote machine using SSH

   cp (-r) file1(folder1) file2(folder2)

   rm (-r) file(folder)

2.count the number of files in the current directory    

       this is one:  

       ls -l . | egrep -c '^-'

       Note:

       ls -1 | wc -l

       Which means:ls: list files in dir

       -1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

       | : pipe output onto...

       wc: "wordcount"

       -l: count lines.
