How do I get the find command to print out the file size with the file name?

Question

find . -name '*.ear' -exec ls -lh {} \;

just the h extra from jer.drab.org's reply. saves time converting to MB mentally ;)

You need to use -exec or -printf. Printf works like this:

find . -name *.ear -printf "%p %k KB\n"

-exec is more powerful and lets you execute arbitrary commands - so you could use a version of 'ls' or 'wc' to print out the filename along with other information. 'man find' will show you the available arguments to printf, which can do a lot more than just filesize.

[edit] -printf is not in the official POSIX standard, so check if it is supported on your version. However, most modern systems will use GNU find or a similarly extended version, so there is a good chance it will be implemented.

a simple solution is to use the -ls option in find:

find . -name \*.ear -ls

That gives you each entry in the normal "ls -l" format. Or, to get the specific output you seem to be looking for, this:

find . -name \*.ear -printf "%p\t%k KB\n"

Which will give you the filename followed by the size in KB.

Using gnu find, I think this is what you want. It finds all real files and not directories (-type f), and for each one prints the filename (%p), a tab (\t), the size in kilobytes (%k), the suffix " KB", and then a newline (\n).

find . -type f -printf '%p\t%k KB\n'

If the printf command doesn't format things the way you want, you can use exec, followed by the command you want to execute on each file. Use {} for the filename, and terminate the command with a semicolon (;). On most shells, all three of those characters should be escaped with a backslash.

Here's a simple solution that finds and prints them out using "ls -lh", which will show you the size in human-readable form (k for kilobytes, M for megabytes):

find . -type f -exec ls -lh \{\} \;

As yet another alternative, "wc -c" will print the number of characters (bytes) in the file:

find . -type f -exec wc -c \{\} \;
