To search and delete empty files in the current directory and subdirectories   find   -type f -empty -delete   -type f is necessary because also directories are marked to be of size zero     The dot    current directory  is the starting search directory  If you have GNU find  e g  not Mac OS   you can omit it in this case   find -type f -empty -delete   From GNU find documentation      If no files to search are specified  the current directory     is used

On Linux  the stat 1  command is useful when you don t need find 1         stat -c  s   filename         rm   filename    The stat command here allows us just to get the file size  that s the -c  s  see the man pages for other formats    I am running the stat program and capturing its output  that s the         This output is seen numerically  that s the outer          If zero is given for the size  that is FALSE  so the second part of the OR is executed   Non-zero  non-empty file  will be TRUE  so the rm will not be executed

You can use the command find to do this  We can match files with -type f  and match empty files using -size 0  Then we can delete the matches with -delete   find   -type f -size 0 -delete
