问题
To count the number of files in a directory, I typically use
ls directory | wc -l
But is there another command that doesn't use wc ?
回答1:
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.
