Find files greater than 100MB and store a list of their names in a file


Hi guys,

I am trying to figure out how to do the following:

Use the appropriate command to locate all files on your server that have a size greater than 100MB and store a list of their names in the file /root/bigfile.

To do this I executed the following command

find -type f -size +100M >> /root/bigfile

but it gives me not only the name of the files but the full path


[root@localhost ~]# cat bigfile
./proc/kcore
./usr/lib/locale/locale-archive
./proc/kcore
./usr/lib/locale/locale-archive

is there a way to copy only the name of the files?

Many thanks!

Have a look at the -printf option

Check the man page for find, the -printf option. The format I think you are looking for would be -printf "%f\n".

Something like this comes to my mind:
Code:
find . -type f -size +5M -exec basename {} \;
but the printf solution is probably better (?).

Another option to get the basename is parameter expansion (probably doesn't make sense in this case, just saying it is an option in general):

kcore
find: /proc/17083/task/17083/fdinfo/6: No such file or directory

Hint: look at -xdev option in: man find (or web-search: find xdev proc)
Also, study shell redirection of stderr to 'the bit bucket': 2>/dev/null

Best wishes on your Linux journey! Remember to 'search first' Here's book info...

You know you should never attempt to manipulate this file, correct?

The option -prune is harder to figure out but you should look at it, too. It's useful in telling find to skip directories, such as /proc
