1995 Version of ANSI (Equivalent to Current ISO Version) of Standard

8.2.9 If

@ expratom V L ifargument


In its argumentless form, If is the inverse of Else. That is, if the value of $Test is 0, the remainder of the line to the right of the If is not executed. If the value of $Test is 1, execution continues normally at the next command.

If exactly one argument is present, the value of tvexpr is placed into $Test; then the function described above is performed.

If with n arguments is equivalent in execution to n If commands, each with one argument, with the respective arguments in the same order. This may be thought of as an implied and of the conditions expressed by the arguments.
