The single exception to this rule is the expansion of the special parameter '@' within double-quotes, as described in Section 2.5.2."
The last sentence is not correct. An argument that consists of an unquoted $@ or $* both initially generates one field per positional parameter. Each word is then subject to pathname expansion, field splitting and empty removal. The former two can be disabled (using `set -f` and `IFS=` respectively) but that does not cause $@ or $* to generate just one field. Proof: $ (set -f; IFS=; set one two '' three; printf '@%s\n' $@; printf '*%s\n' $*) @one @two @three *one *two *three Desired Action: Replace by: "It is only field splitting or pathname expansion that can create multiple fields from a single word. However, as a special exception to this rule, the expansion of the special parameter '@' within double-quotes, as well as the expansion of the unquoted special parameters '@' or '*', may generate multiple fields as described in Section 2.5.2." ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2022-08-03 19:18 McDutchie New Issue 2022-08-03 19:18 McDutchie Name => Martijn Dekker 2022-08-03 19:18 McDutchie Organization => https://github.com/ksh93/ksh 2022-08-03 19:18 McDutchie Section => XCU 2.6 2022-08-03 19:18 McDutchie Page Number => 2319 2022-08-03 19:18 McDutchie Line Number => 74745-74746 ======================================================================
