Here is one approach:
Code:
# Calculate previous hour time-stamp using PERL
TS=$( perl -e '@d=localtime time()-3600; printf "%4d%02d%02d%02d%02d", $d[5]+1900,$d[4]+1,$d[3],$d[2],$d[1]' )

# Touch a temporary file with the calculated time-stamp
touch -t "$TS" tmp_file

# Find files which are older than but not newer than touched file
find . -name "*.log" ! -newer tmp_file -exec ls -l {} \;

Note: Replace ls -l {} \; with rm -f {} \; if results look good.

I hope this helps.

As long as you don't run it between midnight and 1am, you can also do this in ksh without needing to call perl and find (unless you also want to search subdirectories for log files to be removed):
Code:
#!/bin/ksh
set -- $(date "+%m%d %H %M")
touch -t $1$(($2 - 1))$3 timestamp.$$
for i in *.log
do      if [ "$i" -ot timestamp.$$  ]
        then    echo rm "$i"
        fi
done
rm timestamp.$$

Try it and if it looks like it does what you want, remove the echo before the rm "$i".
