# - Matches on source and compiled code
# - Searches in user home directories by default
# - Detects certain strings in files smaller 300 kbyte
# - Does not print anything if nothing was found
# - Appends the file's time stamp of the files in question > good indicator to spot false positives
# - Should work on most Linux systems with bash
