cu
Description
Note: The cu utility is fully supported for compatibility with older UNIX systems.
However, because it is no longer supported by POSIX.2 IEEE standard
1003.2-1992, this utility should be avoided for applications intended to be
portable to other UNIX- branded systems.
cu connects to remote systems specified in the UUCP configuration file. You can
use it for simple terminal connections, or to do simple file transfer with no error
checking.
cu is recognized, but its functions are disabled. Traditionally, it is used for simple
terminal connections to remote systems specified in the UUCP configuration file. cu
requires a direct connection (such as with a modem) to the remote system, but this
is not supported by z/OS.
cut — Cut out selected fields from each line of a file
Format
Description
Options
cut –b list [–n] [file...]
cut –c list [file...]
cut –f list [–d char] [–s] [file...]
cut reads input from files, each specified with the file argument, and selectively
copies sections of the input lines to the standard output (stdout). If you do not
specify any file, or if you specify a file named –, cut reads from standard input
(stdin).
–b list Invokes byte position mode. After this comes a list of the byte positions you
want to display. This list may contain multiple byte positions, separated by
commas (,) or blanks or ranges of positions separated by dashes (–). Since
the list must be a single argument, shell quoting is necessary if you use
blanks. You can combine these to allow selection of any byte positions of
the input.
Attention: When using the –b option with doublebyte characters, you
should also specify the –n option to ensure that entire characters are
displayed. If you do not specify the –n option, cut simply assumes that the
low byte of a range is the first byte of a character and that the high byte of
a range is the last byte of a doublebyte character, possibility resulting in the
misinterpretation of the characters represented by those byte positions.
–c list Invokes character-position mode. After this comes a list of character
positions to retain in the output. This list can contain many character
positions, separated by commas (,) or blanks or ranges of positions
separated by a dash (–). Since the list must be a single argument, shell
quoting is necessary if you use blanks. You can combine these to allow
selection of any character positions of the input.
–d char
Specifies char as the character that separates fields in the input data; by
default, this is the horizontal tab.
–f list Invokes field delimiter mode. After this comes a list of the fields you want to
