Hi

I think the question title says it all. I have tried ls -l -h  **/*.gz to just list the gz files in a directory but i get the error message 'cannot access **/*.gz no such file or directory

Thanks a lot

What directory are the files in?
Did you try  ls -l -h  *.gz

Are you looking in a specific subdirectory? If so, include the directory name, like this:
ls -l -h  sub_dir_name/*.gz

Open in new window

Or do you want to find all *.gz that are 1 subdirectory below the current directory? If so, you need to use find, and tell it to only look 1 level deep, like this:
find -maxdepth 2 -name "*.gz"

Open in new window

Note that you need to use 2 because the current directory is considered the first, and its subdirs are 2, etc.

if you want to list all files in a particular directory, try

ls -ltr *.gz

but that won't include gz files from subdirectories

To find recursively and list the size as well:
find . -name "*.gz" -ls

Open in new window

Hi
Thanks for the replies. I can see that as ever my question isn't worded as well as it could have been. I just want the file name and the size in human readable form (like MB or something). However in order to do this I seem to have to add the -l option which give me a load of other gunk. Or do i need to pipe it into cut to get teh columns I want. I dont use linux very mich. Sorry

Assuming there are no whitespaces in your file names the following will work.

find . -name "*.gz" -ls | awk '{size=$7; name=$11; suf=""; format="8d  ";
if (size>1024) { size /= 1024.0; suf="k"; format="10.1f" }
if (size>1024) { size /= 1024.0; suf="m" }
if (size>1024) { size /= 1024.0; suf="g" }
printf "%"format"%-2s %s\n", size, suf, name; 
}'

Open in new window

or utilising the "-h" flag of "ls" command (which won't align the numbers decimally):

 find . -name "*.gz" | xargs ls -lh | awk '{ printf "%10s %s\n", $5,$9}'

Open in new window
