FFV is a software that verifies and generates checksum files to ensure data integrity. It enables users to confirm the validity of files against reference checksums, improving data security and reducing the risk of errors.

VBinDiff is a software tool that allows users to view files in ASCII and hexadecimal (or EBCDIC) formats. It enables efficient binary file comparisons and provides visual representations of differences between two files.

md5gz, a Bash script, is a utility to calculate the MD5 checksum of compressed files. It runs files through zcat before hashing to provide the checksum of the uncompressed data rather than that of the compressed version, just like the md5sum command.

mktime is a tool that allows users to convert between UNIX timestamps and dates that are readable by humans.

Perlver is a software tool for printing the version of a Perl module. The tool scans and returns the version number of the specified Perl module.

Eack is a utility that runs ack within Emacs, providing enhanced search and analysis capabilities in a small package.
