Full Discussion: How do I check if find had no output

Please put code in code tags.
Code:
#!/bin/bash

if [ $# -ne 1  ]; then
  echo "usage: clean-createTopTen-output-dir ~/outputdir"
  echo "removes CreateTopTen-outputted files from ~/outputdir"
  exit
fi

cleandir=$1

# for now, just delete every file that is not a gif
# but leave dir structure intact
find $cleandir -type f ! -name *gif | xargs -t rm

Change rm to rm -f and that error message will disappear.
Code:
$ rm
rm: too few arguments
Try `rm --help' for more information.

$ rm -f
$

Alternatively, you could do it in xargs.
Code:
$ xargs ls < /dev/null
( current directory contents)

$ xargs --no-run-if-empty ls < /dev/null
$
