Recompress all files in current directory from gzip to bzip2

This solution is similar to [1] except that it does not have any dependency on GNU Parallel. Also, it tries to minimize the impact on the running system (using ionice and nice).

find potentially malicious PHP commands used in backdoors and aliked scripts

I have found that base64 encoded webshells and the like contain lots of data but hardly any newlines due to the formatting of their payloads. Checking the "width" will not catch everything, but then again, this is a fuzzy problem that relies on broad generalizations and heuristics that are never going to be perfect.

What I have done is set an arbitrary threshold (200 for example) and compare the values that are produced by this script, only displaying those above the threshold. One webshell I tested this on scored 5000+ so I know it works for at least one piece of malware.

Order all files oldest to newest then get the last one touched

On the Mac, the 'ls' function can sort based on month/day/time, but seems to lack ability to filter on the Year field (#9 among the long listed fields). The sorted list continuously increases the 'START' year for the most recently accessed set of files. The final month printed will be the highest month that appeared in that START year. The command does its magic on the current directory, and suitably discards all entries that are themselves directories. If you expect files dating prior to 2002, change the START year accordingly.

easily strace all your apache processes

This version also attaches to new processes forked by the parent apache process. That way you can trace all current and *future* apache processes.
