Counting files in a Folder at the Linux Command Line

This command combines ls (directory list) with wc (word count) command to count the number of files in a directory.  I just used it to count over 100k files in a directory and it ran pretty fast, under a second.

Output + time

time ls -1 | wc -l

real	0m0.662s
user	0m0.616s
sys	0m0.039s
