like in my A directory it has 1 file, in B - 2 and in C - 3 . Then how can i print total num of files in this directories?

@chris:

that will just count the directories. not the files in directories.

Do you want to include the directories themselves (A, B, C), or just the files? Do these directories contain subdirectories with more files? If so, how deep do you want to go? Do you want the number of files itemized by directory, or just one number for all files in all directories?

Doing an "ls" on a directory will print all of the files contained within the directory, unless you pass the "-d" flag to ls.

just the files in that directories. total num of files in those directories. and those directories don't have subdirectories. just files. the example that i gave you. in that example ans should be 6.

Code:

ls {A,B,C}/* | wc -l

or

Code:

find {A,B,C} -type f | wc -l

If A, B, and C were just example directories, and you simply want to search the contents of all directories in the PWD:

Code:

ls */* | wc -l

Code:

find . -type f | wc -l

Yeah thanks. That was easy. Thanks a lot.

What if i want to print the directory and how many files does that directory contain...

suicidaleggroll · 10-12-2012, 10:02 AM

That's when the first few examples would come into play

Code:

for dir in *; do
   echo $dir: $(ls "$dir" | wc -l)
done

This could be combined on one line if you don't want to write a script for it

Code:

for dir in *; do echo $dir: $(ls "$dir" | wc -l); done

Suppose you want to count all files within a directory /home/smith/, then do as:
% vi count.sh
And enter following lines:

#!/bin/sh

DIR=/home/smith/
CMD=`ls -la $DIR | wc -l`
echo "Files count is: $CMD"

Then save and exit the file. Make it executable i.e. invoke command % chmod +x count.sh
and then run the script as:
./count.sh
