Description Cai Xianchao 2008-02-29 08:26:02 UTC 
Description of problem:

Version-Release number of selected component (if applicable):
Manpage says that "a‘\’ can be used to quote the delimiter inside l and r." But,
'\' can not be used to quote the delimiter '(', ')', '|' and '>'.

How reproducible:


Steps to Reproduce:
1.[test@RHEL5 ~]$ set test=(ab cd)
2.[test@RHEL5 ~]$ echo $test:s(\(a(A(
Too many ('s.
3.[test@RHEL5 ~]$ echo $test:s)\)a)A)
Too many )'s.
4.[test@RHEL5 ~]$ echo $test:s|\|a|A|
Invalid null command.
5.[test@RHEL5 ~]$ echo $test:s>\>a>A>
Missing name for redirect.
  
Actual results:
The substitution fails and error messages are outputed.

Expected results:
'a' is replaced by 'A'.

I've reopened the bug.

1.[test@RHEL5 ~]$ set test=(ab cd)
Fine. But note:
[vcrhonek@norcus ~]$ echo $test
ab cd
Braces are not part of variable, they are used because variable contains white
space.
set  var = (str1 str2 str3) define shell variable with value consisting of
multiple strings.

2.[test@RHEL5 ~]$ echo $test:s(\(a(A(
Wrong. There's no "(a" to be replaced with "A".
[vcrhonek@norcus ~]$ echo $test:s(a(A(
Ab cd

3.[test@RHEL5 ~]$ echo $test:s)\)a)A)
Wrong. There's no ")a" to be replaced with "A".
[vcrhonek@norcus ~]$ echo $test:s)a)A)
Ab cd

4.[test@RHEL5 ~]$ echo $test:s|\|a|A|
Wrong. There's no "|a" to be replaced with "A".
[vcrhonek@norcus ~]$ echo $test:s|a|A|
Ab cd

5.[test@RHEL5 ~]$ echo $test:s>\>a>A>
Missing name for redirect.
Wrong. There's no ">a" to be replaced with "A".
[vcrhonek@norcus ~]$ echo $test:s>a>A>
Ab cd

Note this:
[vcrhonek@norcus ~]$ set test = ( ab\> cd )
[vcrhonek@norcus ~]$ !:s(\((X(:p
set test = X ab\> cd )

[vcrhonek@norcus ~]$ set test = ( ab > cd )
[vcrhonek@norcus ~]$ !:s>\>>X>:p
set test = ( ab X cd )

So everything works correctly, changing resolution to NOTABUG and man page will
be fixed back in Fedora.
