| Summary | 0001596: Not one, but three expansions may create multiple fields from a single word | |||||||||||
| Description |
Quoting lines 74743-74746: "It is only field splitting or pathname expansion that can create multiple fields from a single word. 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." | |||||||||||
