a file (-f file) or stdin (-f -). That way you could do:
find /path -ctime -1 | clamscan -i -f -
or:
find /path -ctime -1 /tmp/toscan
clamscan -i -f /tmp/toscan
and put it in a nightly cron job. What do you think?
You can use the CVS version - clamscan supports multiple file arguments
from command line, and build a script that executes clamscan on a bunch
of files. You can fall into a problem with special characters and
spaces, though.
Just a thought - perhaps you could modify the tob (Tape Orientated
Backup) scripts to do this. Tob supports full, incremental and
differential file listings.

Tips related to filenames with spaces, quotes etc.:
find /path -ctime -1 -print0 | xargs -0r command
man find:
-print0
True; print the full file name on the standard out
put, followed by a null character. This allows
file names that contain newlines to be correctly
interpreted by programs that process the find out
put.
man xargs:
--null, -0
Input filenames are terminated by a null character
instead of by whitespace, and the quotes and back
slash are not special (every character is taken
literally). Disables the end of file string, which
is treated like any other argument. Useful when
arguments might contain white space, quote marks,
or backslashes. The GNU find -print0 option pro
duces input suitable for this mode.
--no-run-if-empty, -r
If the standard input does not contain any non
blanks, do not run the command. Normally, the com
mand is run once even if there is no input.

[Clamav-users] Suggestion: Read list of files to scan from file/stdin
Hello,
I was looking for a way to set up a cron job to, once per day, scan only
files that have changed in the last day. find works pretty well for that,
but the question is how to get the data to clamscan. My first thought was
xargs, but xargs isn't the most consistent when dealing with spaces/quotes
in filenames, and plus you have a limit on the total size of args passed
to a program. The current best working solution would be to do this:
find /path -ctime -1 -exec clamscan \{\} \;
but that invokes clamscan for EVERY matching file found. Instead, I would
like to request that a new flag, say -f, be added to clamscan/clamdscan
that takes a list of files, one file per line, from a file (-f file) or
stdin (-f -). That way you could do:
find /path -ctime -1 | clamscan -i -f -
or:
find /path -ctime -1 /tmp/toscan
clamscan -i -f /tmp/toscan
and put it in a nightly cron job. What do you think?
