chkrootkit (Check Rootkit) is a Unix-based program intended to help system administrators check their system for local signs of known rootkits. It is a shell script using common UNIX/Linux tools like the strings and grep commands to search core system programs for signatures and for comparing a traversal of the /proc filesystem with the output of the ps (process status) command to look for discrepancies.
