Manual page and help for the uncompress.real Linux command. The uncompress.real command unpacks the specified files - previously compressed with the compress command, with the extension .Z and beginning with a special encoding. The compress and its counterpart uncompres.real commands use an adaptive Lempel-Ziv compression algorithm.
Note that the program normally installed as uncompress is installed as uncompress.real on Debian systems to avoid conflicts with the more commonly used uncompress program of the same name, which is otherwise part of the gzip package.
