bzmore command in Linux (works a bit identical to bzless) is basically used as a filter allowing users to examine compressed or plain text files on full screen at a time. This command can work with both type of files, either the bzip2 compressed files or uncompressed ones. In case if a specified file is non-existing, the bzmore will look for other file with same name, also with a name having suffix .bz2.
While using bzmore, it pauses showing content once the screen is full, and shows –More– at the bottom allow users to switch to next screen to view more by pressing Space. In case if a carriage return is pressed, one more line is displayed.
Technically, the files associated with bzmore is located within /etc/termcap, which includes characteristics of the command, and is also used to determine the window size. Means, if a terminal is capable showing 24 lines, the default window size will be 22 lines.
