Статус выхода (Exit)
If the -S option is used, @TPUT@ checks for errors from each
line, and if any errors are found, will set the exit code to 4
plus the number of lines with errors. If no errors are found,
the exit code is 0. No indication of which line failed can be
given so exit code 1 will never appear. Exit codes 2, 3, and 4
retain their usual interpretation. If the -S option is not used,
the exit code depends on the type of capname:
boolean
a value of 0 is set for TRUE and 1 for FALSE.
string a value of 0 is set if the capname is defined for this
terminal type (the value of capname is returned on
standard output); a value of 1 is set if capname is not
defined for this terminal type (nothing is written to
standard output).
integer
a value of 0 is always set, whether or not capname is
defined for this terminal type. To determine if
capname is defined for this terminal type, the user
must test the value written to standard output. A
value of -1 means that capname is not defined for this
terminal type.
other reset or init may fail to find their respective files.
In that case, the exit code is set to 4 + errno.
Any other exit code indicates an error; see the DIAGNOSTICS
section.
