"find /full/path/to/directory -type f -exec rm {} \;" will delete
all files found below /full/path/to/directory without deleting pipes,
directories, etc.
"find /full/path/to/directory -exec rm {} \;" will blow out everything.
If you don't use an environment variable for the path you run no
risks. Admittedly you can get in trouble with find /$FullPath because
some logic error introduced by a maintenance programmer in the future
could cause $FullPath to resolve to the empty string... you might use
one of these tricks:
#1 - bodge up a sandbox
#!/bin/bash
mkdir /tmp/safedir 2>/dev/null
if cd /tmp/safedir
then
find $FullPath -exec rm {} \;
else
echo ERROR: Unable to clear $FullPath
fi
#2 - sanity check
#!/bin/bash
if [ -n "$FullPath"]
then
find $FullPath -exec rm {} \;
else
echo FATAL ERROR
echo Moronic programming SNAFU
echo variable FullPath is empty!
fi
As a general rule, never script file glob wildcards into bash (because
a big directory will make bash's globbing overrun the shell command
line length limitation of your OS) and always put appropriate sanity
checks into path composition code to detect unset variables.
Hope that helped!
