hi,
do I need to add echo lines on this answer?

Write a bash script that takes the name of a directory as an argument and searches the file hierarchy rooted at that directory for zero length files. Write the names of all zero length files to standard output. If there is no option on the command line, have the script delete the file after displaying its name. An -i option on the command line indicates that the script should ask the user for confirmation before deleting the file.

$ cat zerdel

if [ $1 == -i ]

then

find $2 -empty -print -exec rm -i {} \;

else

find $1 -empty -ok rm -i {} \;

fi

hi there,
mate, you open 10 threads asking homework questions..

ps. reported..

From what I can tell no echos are needed, find should write out the filenames., but you should have answered the question yourself when testing your script. Your $1 and $2 scheme may work, but when parsing command line options in shells 'getopts' is the perferred way. Search this site or google, there are lots of examples.
