ksh print [ -Rnprsu [n]] [arg...] DESCRIPTION
ksh The shell output mechanism. With no flags or with flag - or -, the arguments are printed on standard output as described by echo(1). OPTIONS
The following options are supported: -n suppresses new-line from being added to the output. -R -r (raw mode) ignore the escape conventions of echo. The -R option will print all subsequent arguments and options other than -n. -p causes the arguments to be written onto the pipe of the process spawned with |& instead of standard output. -s causes the arguments to be written onto the history file instead of standard output. -u [ n ] flag can be used to specify a one digit file descriptor unit number n on which the output will be placed. The default is 1. EXIT STATUS
The following exit values are returned: 0 Successful operation. >0 Output file is not open for writing. ATTRIBUTES
