# This testcase demonstrates that backslashes are treated differently
|
||||
# in 1st and 2nd parts of ${var/search/repl}:
|
||||
# if quoted: "${var/search/repl}", and repl contains \a (a non-special char),
|
||||
# the backslash in repl stays; if unquoted, backslash: removed
|

# if quoted ("${var/search/repl}"), and repl contains \a (a non-special char),
|
||||
# the backslash in repl stays; if unquoted, backslash is removed.
|
||||
# But search part does not act like that: \a is always converted to just a,
|
||||
# even in quotes.
|
||||
#
|
||||
# bash4 (and probably bash3 too) result: "Quoted:" results are different -
|
||||
# they have extra backslash before z.

# bash4 (and probably bash3 too): "Quoted:" results are different from
