Input file format


Output file format

embossversion writes just the version number followed by a newline character to end the line.

The output is written to the screen by default, but can be written to a named file by using the '-outfile' option.

The version number is in three parts, separated by '.'s.
The first number is the major version number - this only changes when substantial changes have been made to the look-and-feel of EMBOSS.
The second number is the minor version number - this is incremented whenever a version is released.
The third number is usually '0' but if a minor bug fix has been released that does not warrant a minor version number, this will be incremented.

Data files



embossversion might be called by scripts in automated systems requiring versioning information, or in user-support as a convenient way to ascertain the version of an EMBOSS installation being used remotely.
