10: sseett [-cceeiikknnssttuuvvxx [_n_a_m_e ...] ] (Bourne shell)
11: sseett [[+-]aaeeffhhkkmmnnuuvvxx] [[+-]oo _n_a_m_e] (Korn shell)
12:
13: sseett changes the options of the current shell and optionally sets
14: the values of positional parameters. This command is used
15: implemented by both the Bourne and Korn shells; however, its
16: syntax and options vary from one shell to the other.
17:
18: ***** Bourne Shell *****
19:
20: The shell variable `$-' contains the currently set shell flags.
21: If the optional _n_a_m_e list is given, sseett assigns the positional
22: parameters $11, $22 ... to the given shell variables.
23:
24: sseett recognizes the following options:
25:
26: -cc _s_t_r_i_n_g
27: Read shell commands from _s_t_r_i_n_g.
28:
29: -ee Exit on any error (command not found or command returning
30: nonzero status) if the shell is not interactive.
31:
32: -ii The shell is interactive, even if the terminal is not
33: attached to it; print prompt strings. For a shell reading a
34: script, ignore signals SSIIGGTTEERRMM and SSIIGGIINNTT.
35:
36: -kk Place all keyword arguments into the environment. Normally,
37: the shell places only assignments to variables preceding the
38: command into the environment.
39:
40: -nn Read commands but do not execute them.
41:
42: -ss Read commands from the standard input and write shell output
43: to the standard error.
44:
45: -tt Read and execute one command rather than the entire file.
46:
47: -uu If the actual value of a shell variable is blank, report an
48: error rather than substituting the null string.
49:
50: -vv Print each line as it is read.
51:
52: -xx Print each command and its arguments as it is executed.
53:
54: - Cancel the -xx -vv options.
55:
56: The shell executes sseett directly.
57:
58: ***** Korn Shell *****
59:
60: sseett recognizes the following options. Preceding an option with
61: `-' turns on the option; preceding it with `+' turns it off.
