NMT Utilities Command Line
NMT provides commands for modifying and summarizing data in the NMT configuration (.cnf) files.
Most NMT functionality can be executed in the command line interface (CLI). You can use this feature
to write scripts and batch commands.
Enter all commands on a UNIX command line in the working directory. Most commands use the
following form:
command cnffile [options]
where cnffile is the name of the NMT configuration file.
Several of the commands require additional input, such as names of output files. Before you use one of
these commands, enter
command -h at the UNIX prompt. This calls up help text.
Table 7-1 lists the NMT Command Line Commands.
